---+ OSLC Relationships <blockquote style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 40px; border-width: initial; border-color: initial; border-style: none; padding: 0px"> INCOMPETE AND UNDER discussion </blockquote> At OSLC the notion of relationship is central. Spec. to allow providers to surface relationship information in a RESTful manner. Using OSLC Shape Resources to describe * Relationship: name, description of a relation * Relationship: service providers which are known to support that relationship. * Links: In OSLC today, two resources stand in a certain relation to one another but the existence of this relation is modelled by two OSLC Properties - a link in the forward direction and a link in the other direction. A -> B and B -> A. The link in the other direction has been called the "inverse", "reverse", "complement", "dual", "back" and so on. Here we call it the _inverse link_. * OSLC Leads are aware this is an architectural weakness * ---++ OSLC Relationships Resource An OSLC Resource which enumerates the OSLC Relationships that are configured for the service provider. * *Name*: Relationships * *Type URI*: http://open-services.net/xmlns/oslc#Relationships * *Description*: Defines a set of relationships that a OSLC service provider exposes. * Properties: * See table immediately below * Other OSLC Properties *MAY* be specified by OSLC Services %TABLE{columnwidths="0,180,100,0,0,0"}% | *OSLC Link Properties* | *Type* | *Occurs* | *Extended Property?* | *Description* | | _OSLC Relationships Resource_ ||||| | oslc:relationships | Resource of type oslc:Relationship | zero-or-more | no | Link to oslc:Relationship | These properties are intended to be part of an OSLC Service resource to identify the relationships that exist between service providers. ---++ OSLC Relationship Resource Describes a relationship that exists to other OSLC service providers, and the OSLC Properties which are used to indicate the presence of such a relationship. * *Name*: Relationship * *Type URI*: <span style="color: blue; text-decoration: underline">http://open-services.net/xmlns/oslc#Relationship</span> * *Description*: Defines a single relationship that a OSLC service provider exposes. * Properties: * See table immediately below * Other OSLC Properties *MAY* be specified by OSLC Services %TABLE{columnwidths="0,180,100,0,0,0"}% | *Prefixed Name* | *Data type* | *Occurs* | *Extended Property?* | *Title* | *Description* | | _OSLC Common Properties HERE_ |||||| | _OSLC Relationship Resource_ |||||| | dc:title | XMLLiteral | at-most-one | No | Title | Title of the relationship; this SHOULD include only content that is valid inside an XHTML <span> element. | | dc:description | XMLLiteral | at-most-one | No | Description | Description of the relationship; this SHOULD include only content that is valid and suitable inside an XHTML <div> element. | | oslc:link | Resource of type oslc:Property | exactly-one | No | Link | The OSLC Property that describes the link. | | oslc:inverse | Resource of type oslc:Property | exactly-one | No | Inverse | The OSLC Property that describes the inverse link. | Bringing the oslc:link an oslc:inverse together in a Relationship resource identifies the oslc:Properties as defining the relation - is this strong enough? Should the description of a relationship include a description of the expected/supported OSLC Domains at either end? For example, oslc:domain and oslc:range? I don't like this idea because it leads to a brittleness in the linking, but we might want to discuss. Some RmRelationshipExamples. %COMMENT%
