Notation and Conventions

The key words “MUST”, “MUST NOT”, “REQUIRED”, “SHALL”, “SHALL NOT”, “SHOULD”, “SHOULD NOT”, “RECOMMENDED”, “MAY”, and “OPTIONAL” in this document are to be interpreted as described in RFC2119. Domain name examples use RFC2606.

Introduction

(this section is informative)

This specification builds on the OSLC Core Specification to define the resources and operations supported by an Open Services for Lifecycle Collaboration (OSLC) Automation provider.

Automation resources define automation plans, automation requests and automation results of the software development, test, deployment, and operations lifecycle. They represent individual resources as well as their relationships to other automation resources and to other linked resources outside of the automation domain. The intent of this specification is to define the set of HTTP-based RESTful interfaces in terms of HTTP methods: GET, POST, PUT and DELETE, HTTP response codes, MIME type handling and resource formats. The capabilities of the interface definitions are driven by key integration scenarios and therefore don’t represent a complete setup of operations on resources or resource types. The resource formats and operations may not match exactly the native models supported by automation service providers but are intended to be compatible with them.

Automation, as referenced in this specification, refers to the use of IT systems such as servers, workstations and smart hand-held devices to improve efficiency and reduce the need for manual human interactions in the software development, test, deployment, and operations lifecycle. See the Automation Scenarios page for examples from the build, test and deployment disciplines.

Terminology

Service Provider - an implementation of the OSLC Automation specification as a server. OSLC Automation clients consume these services

Automation Resource - A resource managed by the Automation service provider. The types of resources defined by this specification are Automation Plan, Automation Request and Automation Result.

Automation Plan - Defines the unit of automation which is available for execution.

Automation Request - Defines the submission of the information required to execute an Automation Plan and indicates the desired execution state.

Automation Result - Defines intermediate and final execution status of an Automation Request, along with contributions to the result.

Automation Parameter Definition - Defines an individual input parameter of an Automation Plan. Parameter Definitions provide an indication of the type of the parameter and range of allowed values.

Automation Parameter Instance - Defines an individual input or output parameter instance for an Automation Request or Result.

Base Requirements

Compliance

This specification is based on OSLC Core Specification. OSLC Automation consumers and service providers MUST be compliant with both the core specification and this Automation specification, and SHOULD follow all the guidelines and recommendations in both these specifications.

The following table summarizes the requirements from OSLC Core Specification as well as some (but not all) additional requirements specific to Automation. See the full content of the Automation specification for all requirements. Note that this specification further restricts some of the requirements for OSLC Core Specification as noted in the Origin column of the compliance table. See further sections in this specification or the OSLC Core Specification to get further details on each of these requirements.

Any consumer or service provider behaviors are allowed unless explicitly prohibited by this or dependent specifications; conditional permissive requirements, especially those qualified with “MAY”, are implicitly covered by the preceding clause. While technically redundant in light of that broad permission, OSLC specifications do still make explicit MAY-qualified statements in cases where the editors believe doing so is likely to add clarity.

Specification Versioning

See OSLC Core Specification Versioning section.

Namespaces

In addition to the namespace URIs and namespace prefixes defined in the OSLC Core specification, OSLC Automation defines the namespace URI of http://open-services.net/ns/auto# with a namespace prefix of oslc_auto. This namespace URI and prefix are used to designate the resources defined in this specification and their properties.

Resource Formats

In addition to the requirements for OSLC Defined Resource Representations, this section outlines further refinements and restrictions.

See HTTP Method support table for further clarification on support for HTTP methods and media types for each OSLC Automation resource.

For HTTP GET requests on all OSLC Automation and OSLC Core defined resource types,

  • Automation Providers MUST provide RDF/XML representations. The RDF/XML representation SHOULD follow the guidelines outlined in the OSLC Core Representations Guidance for RDF/XML.
  • Automation Providers MAY provide XML and JSON representations. If provided, the XML and JSON representations SHOULD follow the guidelines outlined in the OSLC Core Representations Guidance.
  • Automation Consumers requesting RDF/XML SHOULD be prepared for any valid RDF/XML document. Automation Consumers requesting XML SHOULD be prepared for representations that follow the guidelines outlined in the OSLC Core Representations Guidance.
  • Automation Providers SHOULD support an [X]HTML representation and a user interface (UI) preview as defined by UI Preview Guidance

For HTTP PUT/POST request formats for Automation resources,

  • Automation Providers MUST accept RDF/XML representations and MAY accept XML representations. Automation Providers accepting RDF/XML SHOULD be prepared for any valid RDF/XML document. If XML is accepted, Automation Providers SHOULD be prepared for representations that follow the guidelines outlined in the OSLC Core Representations Guidance.
  • Automation Providers MAY accept XML and JSON representations. Automation Providers accepting XML or JSON SHOULD be prepared for representations that follow the guidelines outlined in the OSLC Core Representations Guidance.

For HTTP GET response formats for Query requests,

Automation Providers MUST provide RDF/XML and MAY provide JSON, XML, and Atom Syndication Format XML.

When Automation Consumers request:

  • application/rdf+xml Automation Providers MUST respond with RDF/XML representation without restrictions.
  • application/xml Automation Providers SHOULD respond with OSLC-defined abbreviated XML representation as defined in the OSLC Core Representations Guidance
  • application/atom+xml Automation Providers SHOULD respond with Atom Syndication Format XML representation as defined in the OSLC Core Representations Guidance
  • If supported, the Atom Syndication Format XML representation SHOULD use RDF/XML representation without restrictions for the atom:content entries representing the resource representations.

Authentication

See OSLC Core Authentication section. OSLC Automation puts no additional constraints on authentication.

Error Responses

See OSLC Core Error Responses section. OSLC Automation puts no additional constraints on error responses.

Pagination

OSLC Automation service providers SHOULD support pagination of query results and MAY support pagination of a single resource’s properties as defined by the OSLC Core Specification.

Labels for Relationships

Automation relationships to other resources are represented as properties whose values are the URI of the object or target resource. When an Automation relationship property is to be presented in a user interface, it may be helpful to provide an informative and useful textual label for that relationship instance. (This in addition to the relationship property URI and the object resource URI, which are also candidates for presentation to a user.) To this end, OSLC providers MAY support a dcterms:title link property in Automation resource representations, using the anchor approach outlined in the OSLC Core Links Guidance.

RDF/XML and XML example using reified statement:

<rdf:RDF 
     xmlns:dcterms="http://purl.org/dc/terms/" 
     xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"

Automation Resource Definitions

The Automation resource properties are not limited to the ones defined in this specification; service providers may provide additional properties. It is recommended that any additional properties exist in their own unique namespace and not use the namespaces defined in this specification.

A list of properties is defined for each type of resource. Most of these properties are identified in OSLC Core Appendix A: Common Properties. Any exceptions are noted. Relationship properties refer to other resources. These resources may be in any OSLC domain (including Automation).

The diagram below shows the relationships between Automation Resources.

Diagram of OSLC Automation relationships

For all resource types defined in this specification, all required properties (those defined with an occurrence of exactly-one or one-or-many) MUST exist for each resource and must be provided when requested. All other properties are optional, and might not exist on some or any resources; those that do not exist will not be present in the returned representation even if requested, while those that do exist MUST be provided if requested. Providers MAY define additional provider-specific properties; providers SHOULD use their own namespaces for such properties, or use standard Dublin Core or RDF namespaces and properties where appropriate.

If no specific set of properties is requested, all properties are returned - both those defined in this specification as well as any provider-specific ones. See Selective Property Values in OSLC Core Specification.

Consumers of OSLC Automation services should note that some resources may have a very large number of related resources, and that some resources may be very large and/or expensive to compute. For this reason, consumers are strongly encouraged to use the oslc.properties parameter to limit the properties returned from a request to the subset required. See Selective Property Values in OSLC Core Specification.

Automation consumers creating Automation Requests MUST use the oslc:occurs attribute of the parameterDefinition, if present, to determine if a given parameter is required when creating the Automation Request. If the oslc:occurs attribute indicates the parameter is required (exactly-one or one-or-more), the service provider must guarantee the named parameter will be present in the Automation Result either as an oslc_auto:inputParmeter when unmodified during execution, or as an oslc_auto:outputParameter when modified during execution.

Automation Service Provider Capabilities

Asynchronous and Synchronous Automation Execution

An OSLC Automation service provider is generally assumed to implement automation requests asynchronously. In this model, a client creates an automation request and then later queries a collection of automation results for the particular result(s) related to its request. For generality, it is also assumed that results may be contributed asynchronously by a set of distributed processes, where each contributor adds its contribution(s) to the result via HTTP PUT. When a provider creates an automation request, it can also include an automation result, which might or might not yet be finished at the point in time when the provider responds to the create request. Providers can persist automation results for as long as they deem reasonable. Consumers are assumed to poll for updates to automation results until they have finished. Once a request has finished, the provider may remove it at any time. An automation result is “finished” when it has an oslc_auto:state predicate with an object of oslc_auto:complete or oslc_auto:canceled or an oslc_auto:verdict property with a value other than oslc_auto:incomplete.

Automation Provider Sub-Domains

An instance of an OSLC Automation service provider might provide services for one or more particular automation sub-domains (e.g. test or build automation). Automation service providers MAY declare sub-domain information in the Service Provider document by specifying a sub-domain value in the oslc:usage attribute on the oslc:Service resource in the Service Provider document. Valid sub-domain values are:

  • http://open-services.net/ns/auto#Build: Indicates that the related service provider or services provide build automation capabilities - the process of converting source code artifacts into software artifacts such as executables, libraries and documentation.
  • http://open-services.net/ns/auto#Test: Indicates that the related service provider or services provide test automation capabilities - the process of executing tests on a system under test and comparing the results of the tests to pass/fail conditions.
  • http://open-services.net/ns/auto#Deploy: Indicates that the related service provider or services provide deployment capabilities - the process of executing processes and procedures to ready systems and software for use.

An automation service provider which is a general-purpose automation provider, or a provider not wanting to provide a sub-domain should provide an oslc:usage value of http://open-services.net/ns/auto. If no oslc:usage attribute indicating a sub-domain is present, the default is assumed to be http://open-services.net/ns/auto.

Sub-domain Example

Example of a service provider document fragment with a 2 Services which are identified as related to the Test and Deploy sub-domains:

<oslc:serviceProvider>
     <oslc:ServiceProvider>
          <oslc:service>
               <oslc:Service>
                    <oslc:usage rdf:resource="http://open-services.net/ns/auto#Test">
                    <oslc:queryCapability>
                        ...
                    </oslc:queryCapability>
                    <oslc:creatonFactory>
                        ...
                    </oslc:creationFactory>
                        ...
               </oslc:Service>
          </oslc:service>
          <oslc:service>
               <oslc:Service>
                    <oslc:usage rdf:resource="http://open-services.net/ns/auto#Deploy">
                    ...
               </oslc:Service>
          </oslc:service>
     </oslc:ServiceProvider>
</oslc:serviceProvider>

Resource Shapes

OSLC Automation service providers MAY support Resource Shapes as defined in OSLC Core Specification Appendix A

Service Provider Resource

OSLC Automation service providers MUST provide a Service Provider Resource that can be retrieved at a implementation dependent URI.

OSLC Automation service providers MAY provide a Service Provider Catalog Resource that can be retrieved at a implementation dependent URI.

It is RECOMMENDED that OSLC Automation service providers provide a oslc:serviceProvider property for their defined resources that will be the URI to a Service Provider Resource.

Creation Factories

If an OSLC Automation service provider supports the creation of resources, there MUST be at least one Creation Factories entry in the Services definition.

See HTTP Method support table for further clarification on support for HTTP methods and media types for each OSLC Automation resource.

Query Capabilities

OSLC Automation service providers SHOULD have at least one Query Capabilities entry in the its Services definition that allows a client to query !AutomationResults.

Note: OSLC Automation does not require providers to keep resources accessible forever. Clients should not expect automation results to be available for any particular length of time once the request has finished (has a state of completed or canceled). Some providers might respond to an AutomationRequest creation request with an AutomationRequest that is also an AutomationResult, and might make the result inaccessible immediately thereafter.

Note: If an OSLC Automation provider does expose a Query Capability that applies to AutomationResults, and if its AutomationRequest creation responses are not also AutomationResults, then its Query Capability is the only Automation-defined way for clients to find the corresponding AutomationResults.

The Query Capability MUST support these OSLC query parameters and MAY support others:

  • oslc:where
  • oslc:select

If shape information is NOT present with the Query Capability, service providers SHOULD use the default properties defined in OSLC Core RDF/XML Examples to contain the result.

Selective Property Values

OSLC Automation providers SHOULD support the oslc.properties syntax for selective property value retrieval when a resource is accessible via its resource URI.

Delegated UIs

OSLC Automation service providers support the selection and creation of Automation resources as defined by Delegated UIs in OSLC Core.

The service providers supports requirements for delegated UIs is as follows:

Automation Resource Selection Creation
AutomationPlan SHOULD MAY
AutomationRequest MAY SHOULD
AutomationResult SHOULD MAY

This is new for 2.1: START

Resource Template Creation Dialog

Resource Template Creation Dialog is a creation dialog delegated UI that is creating an automation request without initiating the execution of the automation plan.

To enable Resource Template Creation, an OSLC Service MUST provide a creation dialog with rdf:type “http://open-services.net/ns/auto#TemplateDialog”. (Note: this may be multi-typed with rdf:type oslc:Dialog.)

Regardless of how the response from the UI Provider is conveyed to the UI Consumer, the response SHOULD be formatted as defined by oslc:results

The AutomationRequest returned as resource in the olsc:results is subject to some limitations that do not apply to the other AutomationRequests resources:

  1. The resource MAY be temporary and the consumer SHOULD get it within a limited period of time (at least 15 minutes)
  2. TThe resource MAY not be persisted and therefore MAY not be able to be queried. Consumers that want to be interoperable SHOULD presume that the resource is not persisted and cannot be queried.

Service providers MAY support prefilling on resource template creation dialog.

Executing the template Automation Request

TODO - that standard operation is to treat the template as text (or bytes). If the consumer changes anything they have to know what they are doing. - Umberto

When a template Automation Request is created, is is not queued for execution. It is the responsibility of the consumer to decide when it is ready to be executed. The standard way to queue an Automation Request template for execution is to submit it to a Creation Factory. However the provider may provide other ways, in addition to or in place of the Creation Factory, that the consumer must use when it is ready to have the Automation Request executed.

The provider describes how to queue a template Automation Request for execution using one or more oslc:binding properties. The target of this property MAY be any “interaction pattern” as defined by the OSLC Core Actions 2.0 Specification, but if the dialog is discoverable from a Service in a Service Provider Catalog, then the provider MUST provide at least one oslc:binding property whose target is the Creation Factory interaction pattern.

If multiple oslc:binding properties are present, they MUST be alternatives to each other.

When a consumer is ready for an Automation Request template to be queued for execution, it uses one of the oslc:binding properties on the dialog to create a concrete (i.e. non-template) Automation Request on the provider. It does this by following the instructions of the “interaction pattern” of that binding, as defined by the OSLC Core Actions 2.0 Specification, or the interaction patterns defined by this specification, or patterns defined by other specifications.

Note: There are two major contexts in which Template Creation Dialogs may be discovered. The first is in OSLC Service Provider Catalogs. Consumers that are only looking for dialogs in this context need only implement the Creation Factory interaction pattern. The second context is OSLC Core Actions. Consumers that are looking for dialogs in this context should choose a specification profile from the Actions specification, and implement the interaction patterns described in that profile.

A consumer chooses which oslc:binding value to use based on which implementation patterns it understands. If there are no oslc:binding values whose interaction patterns are understood by the consumer then the Automation Request template cannot be used by this consumer and the consumer SHOULD indicate this to the user instead of allowing them to use the dialog.

This is new for 2.1: END

State and Verdict properties

OSLC Automation service providers can identify the state and verdict using references to property values in the OSLC Automation vocabulary or to property values that are not in the Automation vocabulary (i.e. in the service provider’s own vocabulary). It is expected that the state and verdict values will be URI references to property values, but inline resources defining the state and verdict property values are also valid. Automation service providers MUST use at least one verdict (Automation Results) and state (Automation Requests and Results) defined in the OSLC automation vocabulary in addition to any states or verdicts not in the Automation vocabulary.

The additional property values for oslc_auto:state are:

  • http://open-services.net/ns/auto#new - used to indicate an automation request or result has just been created in the service provider and has not yet been acted upon.
  • http://open-services.net/ns/auto#queued - primarily used to indicate an automation request or result is queued for additional actions by the service provider
  • http://open-services.net/ns/auto#inProgress - used to indicate an automation request or result is active in the service provider.
  • http://open-services.net/ns/auto#canceling - used to indicate the service provider is in the process of canceling an automation request or result.
  • http://open-services.net/ns/auto#canceled - used to indicate that an automation request or result has been canceled.
  • http://open-services.net/ns/auto#complete - used to indicate that an automation request or result is complete.

The additional property values for oslc_auto:verdict are:

  • http://open-services.net/ns/auto#unavailable - used to indicate an automation result is in a state where a final verdict such as oslc_auto:passed or oslc_auto:failed is not yet available. Usually used when the result is in a state other than oslc_auto:complete.
  • http://open-services.net/ns/auto#passed - used to indicate an automation result represents a successful execution.
  • http://open-services.net/ns/auto#warning - used to indicate an automation result represents an execution which encountered conditions which prevented successful execution but did not result in a failed execution.
  • http://open-services.net/ns/auto#failed - used to indicate an automation result represents a failed execution.
  • http://open-services.net/ns/auto#error - used to indicate an automation result has completed but did not run successfully due to some error. This could be a timeout, automation coding error, network problem or other error which prevented the automation from running successfully to a passed, warning or failed verdict as described above.

OSLC Actions and Automation

This specification defines an extension of the OSLC Actions 2.0 specification. That specification provides “a means of advertising actions (or operations) that can be performed on (or in the context of) a specific resource”. This relates to Automation in two ways: firstly, Automation Requests can be used as an “interaction patten” by which actions can be executed, and secondly, Actions can provide a way to aid management and the lifecycle of automation.

The Actions specification reuses this specification to define an Automation Request interaction pattern, which can be used to execute actions. It also provides a “specification profile” against which implementations can be implemented, which providers interoperability based on providers and consumers both using that interaction pattern. This specification extends the Actions specification by defining the following two interaction patterns which are useful in the management of automation.

Discovering actions and choosing bindings

Discovering executable actions and choosing bindings

For information on how to discover actions on resources and how to choose which binding to use for execution, see the OSLC Actions 2.0 specification.

Discovering actions that will be executable after an Automation Request completes

One of the uses of actions is to advertise what can be performed as a result of an Automation Request completing. For example, tearing down a deployed system or promoting or deleting a build. If the Automation Request resulted in a new resource being created (e.g. a resource representing the deployed system, or a resource representing the build) then it is expected that that resource would be linked to as an oslc_auto:contribution on the Automation Result, and any action in the context of that new resource would be linked to as an oslc:action on that resource. However, consumers may not know which contributions to check for action, so any actions that would make sense to follow up the execution of an Automation Request - whether immediately or at a later time - SHOULD be advertised on the Automation Result in addition to (or instead of) on a contribution.

Future actions

It is sometimes useful to know what actions will be available before the Automation Request is completed (for example, for scheduling automated processes that will execute in their entirety without user intervention).

To enable this, providers MAY include “future actions” on an Automation Plan using the oslc_auto:futureAction predicate. These SHOULD point to resources of type oslc:Action which describe an action that may be executed after an execution of this Automation Plan has completed. As such, these oslc:Action resources SHOULD NOT contain any bindings that can be executed immediately. (Note: This means that bindings using the “template dialog interaction pattern” may be present, but this specification does not define how to use them. In such a binding it would not make sense to specify a “template dialog execution binding”, as only the configuration stage is possible at this time, not the execution stage.)

These future action resources describe what kind of actions are available on the result, so consumers can present these to users in preparation for when the execution has completed, and so the oslc:Action resources SHOULD include all the properties needed to render a display of the action. These oslc:Action resources SHOULD NOT be anonymous nodes, so they can be linked to by the executable actions on the results.

The execution of these future actions requires an executable action on an Automation Result. When an Automation Plan containing future actions is executed, any of those actions that are applicable to the generated result SHOULD have equivalent executable action, linked to using the oslc:action predicate, from the Automation Result. Each of these actions should use the oslc_auto:executes predicate to link to the future action on the Plan that it relates to. This allows consumers to map a user selection of future actions on the plan to executable actions on the result. Each future action SHOULD have at most one executable action linking to it from each result. (Note: If the future action on the plan specified a binding using the template dialog interaction pattern, then the bindings on any executable action on the Result that link to that future action may be intended as template dialog execution bindings for that template dialog (see below), but this specification does not specify that).

See the [Temporary deployment scenarios] for a worked example of future actions.

Deciding how to use Actions and Automation together

This section is non-normative.

When implementing a provider of Automation Plans, you can decide whether to expose those plans through Actions or not. This section addresses that decision.

There are two main issues that come into play: discovery and execution. In the Automation 2.0 specification, which predated the OSLC Actions specification, Automation Plans were discovered through query capabilities or selection dialogs on a service provider. This was the only way to discover them. Actions provide an additional option for discovery, in the context of any given resource. That is, is a given Automation Plan “acts on” another resource, it makes sense for that resource to point to that Automation Plan, including information on what executing that plan will achieve. (Plans discovered via Actions can still be made discoverable through the normal means as well, for consumers who don’t want to browse other resources, but instead just want to directly list or select an Automation Plan).

Automation Plans have a well-defined means of requesting execution. Automation Plans are one option for how providers can allow their actions to be executed. However, unlike plain Automation Plans discovered from a query capability or selection dialog, actions allow providers to specify other means of execution in addition to or instead of Automation Plans (while still supporting predictable iteroperability through being implemented against “implementation profiles”). See the information on “interaction patterns” and “implementation profiles” in the OSLC Actions 2.0 specification for more information.

Discovery Execution
Automation Plans only Query capabilities/Selection dialogs Creation of Automation Request
Actions On other resources (which will be the context of the execution) Creation of Automation Request
(Actions’ Automation Plans can also be made available through query capabilities or selection dialogs as with other plans) (Actions can also provide other non-Automation Plan bindings that the consumer can choose as an alternative)

OSLC Actions Extensions

Teardown action type

This specification defines the RDF class oslc_auto:TeardownAction, as an rdfs:subClassOf oslc:Action, with the meaning that any action of this type MUST have the semantics of tearing down some deployed resource. It is likely that such a deployed resource was deployed using an OSLC Automation deployment plan, but this MAY not be the case. That is, it is defined as the opposite of the semantics of a standard Automation Plan or Request in the oslc_auto:Deploy subdomain (but the actual opposing Plan or Request MAY not exist).

Automation Request interaction pattern

This interaction pattern is defined by the OSLC Actions 2.0 specification (for reuse by other domain specifications).

Creation Factory interaction pattern

This section defines OSLC Core’s Creation Factories as an Actions 2.0 interaction pattern.

Pattern recognition rule

For any action binding that uses this interaction pattern:

  • at least one rdf:type property MUST have the value oslc:CreationFactory.

A binding is deemed to use this pattern if it meets these restrictions.

Additional provider constraints

The binding MUST adhere to the requirements on Creation Factories as defined by the OSLC Core 2.0 specification.

Execution

To execute an action using this interaction pattern, a consumer MUST follow the instructions for Creating an OSLC Defined Resource in the OSLC Core 2.0 specification.

This interaction pattern does not define how the consumer “forms an representation of that resource including the desired and required property values”. (Note: the Template Dialog interaction pattern defines one such way, when this interaction pattern is used in that context). If a consumer does not know how to construct or locate such a representation, then it MUST NOT execute a binding using this interaction pattern.

Template Dialog interaction pattern

This section defines the Resource Template Creation Dialog, as defined in this specification, as an Actions 2.0 interaction pattern.

This interaction pattern consists of the consumer displaying a delegated UI dialog to a user for them to configure the action, for the consumer to execute at “a later time (or times)”.

The dialog recognized by a binding using this pattern is displayed to the user to configure the action. The dialog generates some resource (which may be long- or short-lived) which represents this configuration in some way. This configuration step is taken with the user present. At the time when execution is required, when the user may or may not be present, the consumer uses the resource returned by the dialog to execute the action as defined by the template dialog’s execution bindings.

Pattern recognition rule

For any action binding that uses this interaction pattern:

  • at least one rdf:type property MUST have the value oslc_auto:TemplateDialog.

A binding is deemed to use this pattern if it meets these restrictions.

Additional provider constraints

In addition, Action bindings using this interaction pattern:

  • MUST adhere to the requirements on Resource Template Creation Dialog as defined by this specification.
  • MUST use oslc:binding properties on the action binding itself to recognize one or more execution bindings, which will be used at the later time to execute the action. These are the bindings that are used to execute at a later time the action that was configured by this dialog. They are referred to elsewhere as “template dialog execution bindings”, that is, the bindings that can be used to execute the result of a template dialog. (If an execution binding uses more than one interaction pattern then any of those patterns MAY be ones that are not to be used for these template dialog execution bindings, on the condition that at least one of them is allowed for template dialog execution bindings.)

Execution

This is a two-stage interaction pattern, which can be used to execute the action at a later time, for example when the user is no longer present, or after additional steps such as approval have taken place. In this interaction pattern, the consumer is in charge of when the action is executed. (If the provider needs to be in charge, the standard “delegated UI dialog for immediate execution” interaction pattern can be used, with the exception that the provider doesn’t execute the action immediately.)

To execute an action binding using this interaction pattern, a consumer MUST follow the requirements in the OSLC Core Delegated UI specification to display the dialog, but where oslc_auto:TemplateDialog is used in place of oslc:Dialog.

The dialog MUST either return a URI (in the same manner as a Resource Template Creation Dialog does) or an error code. If the dialog returns a URI, then the consumer SHOULD perform an HTTP GET request on that URI immediately and store the result of that request to be used at the later time to execute the action.

If and when the consumer comes to execute the action at the later time, then the consumer MUST follow the instructions of the interaction pattern of one of the execution bindings linked to from this dialog (see Additional provider constraints above), but with the changes as described under the execution bindings section below. If any of the execution bindings use more than one interaction pattern and any of these interaction patterns are not allowed for template dialog execution bindings, then the consumer MUST NOT use that interaction pattern – but they MAY use that binding with another interaction pattern that it supports where that other interaction pattern supports use for template dialog execution bindings.

Template dialog execution bindings

Template dialog execution bindings MAY use the following interaction patterns for the “later time” execution of this interaction pattern, by following the associated instruction:

Template dialog execution bindings MUST NOT use solely the following interaction patterns, and consumers MUST NOT use these interaction patterns on template dialog execution bindings:

Other specifications that define new interaction patterns MAY state whether or not those interaction patterns may be used by template dialog execution bindings, and if they are allowed then how to use the template to execute them.

Automation Specification Guidance

This section is informative.

Canceling the execution of an automation

The Automation Request and Automation Result resources have an oslc_auto:desiredState attribute. A consumer can indicate a desire to cancel the execution of an automation by doing a PUT to the artifact with this attribute set to a value of http://open-services.net/ns/auto#canceled. If the service provider supports cancelation of automation executions, the receipt of a PUT with this attribute set should trigger the necessary provider processing. If the cancelation is successful, the service provider should set the appropriate artifact oslc_auto:state to http://open-services.net/ns/auto#canceled.

  • When only an Automation Request is active (Automation Result not created yet), the consumer should request cancelation by setting oslc_auto:desiredState on the Automation Request.
  • When Automation Requests and Automation Results are active (in an oslc_auto:state other than oslc_auto:canceled or oslc_auto:complete), the consumer should request cancelation by setting oslc_auto:desiredState on the Automation Request.
  • When only an Automation Result is active (Automation Request completed, canceled or no longer exists), the consumer should request cancelation by setting oslc_auto:desiredState on the Automation Result.
  • Consumers are responsible for checking the status code of the response to the request for cancelation and for checking the oslc_auto:state of the resource.

Responses to Cancelation Requests

If a service provider does not support cancelation of an automation, or if an error occurs preventing successful cancelation, the service provider should respond to the PUT request with an HTTP status code 500 and an OSLC Error Resource detailing the cause for the failed cancelation.

State consistency

The Automation Request and Automation Result resources have an oslc_auto:state attribute. Automation service providers should, where possible, enforce state consistency for related Automation Requests and Results. In general, this means an Automation Result in a final state (completed, canceled) should not have a related Automation Request in a non-final state. Other contradictions such as completed Automation Result with a new Automation Request should also be avoided. Suggested consistent (C) and inconsistent (I) states are:

Automation Result
AutoRequest new queued inProgress canceling canceled complete
new C I I I I I
queued C C I I I I
inProgress C C C I I I
canceling C C C C C C
canceled I I I C C I
complete C C C C C C

Parameters Added During Execution

When Automation Requests are created for an Automation Plan, the creator of the request supplies oslc_auto:inputParameter attributes based on the oslc_auto:parameterDefinition attributes found in the Automation Plan instance. There are scenarios where a provider may add additional parameters during the course of execution and a consumer of Automation Results might wish to discover what these added parameters will be. One method of discovery is for the consumer to simply examine the oslc_auto:outputParameter attributes of the Automation Result. This may not be sufficient for consumers who have a need to know the added parameters prior to executing the Automation Plan.

Service providers can advertise which parameters will be added during the course of execution using the oslc:readOnly attribute of the oslc:Property resource which is the basis for the oslc_auto:parameterDefinition in the Automation Plan. By setting oslc:readOnly to true, the provider indicates that this parameter is not available for the consumer to set, but will or may be added to the Automation Result’s oslc_auto:outputParameters. Whether it is guaranteed to be added to the Result is based on the value of oslc:occurs for the specific parameterDefinition.

Example 1: An Automation Plan parameterDefinition fragment showing a parameter guaranteed to be added during execution

<oslc_auto:parameterDefinition>
    <oslc:name>DeployedIPAddress</oslc:name>
    <oslc:readOnly>true</oslc:readOnly>
    <oslc:occurs>http://open-services.net/ns/core#Exactly-one</oslc:occurs>
