Architecture Management - Link Type Format

1.0 SPECIFICATION DRAFT

Introduction

A link type represents type of link that is or can be used when defining links from AM resources. The type has an ID (expressed as a URI), whose universally accepted semantics may be defined elsewhere. This resource represents the definition as it is used by this service provider. It is meant to make it easy for clients to get a list of known or registered link types with human readable definitions that can be used in client user interfaces.

Namespaces

XML namespace abbreviations used in this specification:

• rdf - RDF XML namespace - http://www.w3.org/1999/02/22-rdf-syntax-ns#
• dcterms - The Dublin Core Metadata Terms namespace - http://purl.org/dc/terms/
• foaf - Friend of a Friend namespace - http://xmlns.com/foaf/0.1/

Representation

The media type used for this RDF/XML representation SHOULD be application/rdf+xml.

The resource MUST be an XML document with the root element <rdf:RDF>.

The resource MUST include at least one <rdf:Description> and the rdf:about attribute MUST specify the absolute URI of the link type.

The following properties are defined as XML child elements for link type resources:

Examples

Example 1. All optional elements included, FOAF identities

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

  <rdf:Description rdf:about="http://example.com/linktype/depends">

    <dcterms:title>Depends</dcterms:title>

    <dcterms:description>
       The source end of this link depends on the target end.
    </dcterms:description> 

    <dcterms:created rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">
       2009-10-20T19:49:47-04:00
    </dcterms:created>

    <dcterms:creator rdf:resource="https://example.com/users/dan">
       <foaf:Person>
          <foaf:name>Dan Designer</foaf:name>
          <foaf:mbox rdf:resource="mailto:dan@example.com" />
          <foaf:img rdf:resource="https://example.com/users/photo/dan" />
       </foaf:Person>
    </dcterms:creator>

    <dcterms:modified rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">
       2009-11-03T08:53:00-04:00
    </dcterms:modified>

    <dcterms:contributor rdf:resource="https://example.com/users/ana">
       <foaf:Person>
         <foaf:name>Ana Analyst</foaf:name>
         <foaf:mbox rdf:resource="mailto:ana@example.com" />
         <foaf:img rdf:resource="https://example.com/users/photo/ana" />
       </foaf:Person>
    </dcterms:contributor>

  </rdf:Description>

</rdf:RDF> 

Example 2. Only Required Return Elements

In this example the link type is externally defined (leveraging the Dublin Core term license), and specified in the rdf:about attribute.

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

  <rdf:Description rdf:about="http://purl.org/dc/terms/license">
    <dcterms:title>Distribution License</dcterms:title>
  </rdf:Description>

</rdf:RDF> 

Example 3. All simple user identities

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

  <rdf:Description rdf:about="http://example.com/linktype/depends">

   <dcterms:title>Depends</dcterms:title>
   <dcterms:description>
      The source end of this link depends on the target end.
   </dcterms:description>

   <dcterms:created rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">
      2009-10-20T19:49:47-04:00
   </dcterms:created>
   <dcterms:creator>Dan Developer</dcterms:create>

</rdf:RDF>
