---+!! OSLC Core Specification:<br />RDF/XML Representation Examples

By: The [[OslcCore][OSLC Core Workgroup]]

%TOC{depth="4"}%

---++ Overview

In this section we introduce a fictional service with two resource types and then provide examples of representations of those resources, a Resource Shape, a Query Resource Shape, a Service Provider and query results in RDF/XML format. These example representations follow the [[OSLCCoreSpecAppendixRepresentations][OSLC Core Specification: Appendix B]] which uses a subset of RDF/XML. Note that clients should be prepared to any form of RDF/XML not just the one shown in these examples.

Also, note that we also provide [[OSLCCoreSpecJSONExamples][JSON Examples]] and [[OSLCCoreSpecTurtleExamples][Turtle Examples]] that match the examples in this appendix.

---++ Example Resources: fictional OSLC Blog Service

For the sole purpose of providing representation examples, we will define a fictional OSLC Blog Service with two resources: Blog Comment and Blog Entry. Each resource has a small set of required properties and each Comment is associated with an Entry. We will use these definitions in the RDF/XML examples in this appendix and in the JSON, Atom XML and Turtle examples that follow.

For example, we will define the blog entry and blog comment resources as follows:

   * *Name*: =Entry=
   * *URI*: =http://open-services.net/ns/bogus/blogs#Entry=
   * *Properties*: 
      * =dcterms:title= (XML Literal, exactly-one) title of Podcast
      * =dcterms:modified= (!DateTime, exactly-one) - date/time that comment was created
      * =dcterms:creator= (Local In-Line Resource of type =foaf:Person=, exactly-one) - name of comment author
      * =dcterms:content= (XML Literal, exactly-one) - content of the comment

   * *Name*: =Comment=
   * *URI*: =http://open-services.net/ns/bogus/blogs#Comment=
   * *Properties*: 
      * =dcterms:modified= (!DateTime, exactly-one) - date/time that comment was created
      * =dcterms:creator= (Resource, In-Line, range =foaf:Person=, exactly-one) - name of comment author
      * =dcterms:content= (XML Literal, exactly-one) - content of the comment
      * =blog:entry= (Resource, exactly-one of type =blog:Entry=) - link to the Blog Entry

Next, the RDF/XML examples for the key resources in our fictional OSLC Blog Service.

---+++ Specifying the shape of a query result

Assuming that the OSLC Core Query Syntax is being used, the query expression itself can determine the shape of the query result. Still there are reasons to provide more information to consumers so that they can understand what fields can be queried and understand the format of the data that is returned. There are several approaches that an OSLC specification can take. Here are three possibilities that we will explore further:

   1 *Specify no resource or property types*. Specify the fields that are available for query in the text of the specification, so that people know how to write query expressions, and return the default as property-values about resources using =rdf:Description= and =rdfs:member=. The drawback to this approach is that an automated query build will not be able to discover how to create a query expression.
   1 *Specify a resource type but no property type*. In the Service resource in the definition of the Query Capability, add an =oslc:resourceType= property-value to specify the resource type to be used for the query result. This will enable people and query builders, to a limited extent, to discover the properties that can be queried. You can then return the query results using the defined resource type and =rdfs:member= to hold each query result.
   1 *Specify both via Query Resource Shape*. In the Service resource in the definition of the Query Capability, add an =oslc:resourceShape= property-value to specify a complete Resource Shape that defines the shape of the query. The shape should specify both a resource type to be used for the results, and a member property to be used to represent individual query results. This will enable people and query builders to discover query-able fields and the shape specifies the form that will be returned.

---++++ Specify no resource or property types

This is option #1 above. Instead of specifying a full Resource Shape, we do not specify result types and simply return property-values about the query result URIs in a standard RDF/XML form. Because there is no resource-type, we can use an RDF-standard =rdf:Description= to contain the query results and we can use RDFS standard =rdfs:member= for each result.
