This vocabulary defines terms used to describe RDF services so that they can be discovered. A RDF service is characterised by the vocabularies, classes, properties, and concepts it can handle.
The description is built as a set of properties of the connection point resource (a node which URI is the URL of the service). Services can publish their SDDs as sets of 'keywords', so they can be discovered via keyword-based lookups. In absense of RDF-aware search engines, regular search engines can be used (see RDFGoo and RDF Facets for details).
The URI for this vocabulary is
http://purl.org/vocab/riro/ddl#
When used in XML documents the suggested prefix is ddl
Each class or property in the vocabulary has a URI constructed by appending a term name to the vocabulary URI. For example:
http://purl.org/vocab/riro/ddl#handlesNamespaceUri The term name for a property always starts with an lowercase character. Where the term name is comprised of multiple concatenated words, the leading character of the second and each subsequent word will be an uppercase character. For example:
handlesNamespaceUri handlesInstancesOfThis vocabulary defines no classes and 4 properties .
| Term Name | Type | Definition |
|---|---|---|
| handlesNamespaceUri | property | The URI of the namespace understood by the service. |
| handlesInstancesOf | property | A Class of resources understood by the service. |
| handlesProperty | property | A property (relation) understood by the service. |
| handlesConceptsIn | property | A SKOS concept scheme understood by the service. |
Definition: [The value of this property is] The URI of the namespace understood by the service.
The URI should include trailing # or /. The format is the same as used in N3 @prefix, RDF/XML xmlns declarations, and vann:preferredNamespaceUri annotations.
| URI: | http://purl.org/vocab/riro/ddl#handlesNamespaceUri |
|---|---|
| Label: | handles namespace URI |
| Domain | rdfs:Resource |
| Range | xsd:string |
Definition: [The value of this property is] A Class of resources understood by the service.
A resource belonging to this class (having it as its rdf:type) may serve as a potential input to the service.
| URI: | http://purl.org/vocab/riro/ddl#handlesInstancesOf |
|---|---|
| Label: | handles instances of |
| Domain | rdfs:Resource |
| Range | rdfs:Class |
Definition: [The value of this property is] A property (relation) understood by the service.
An RDF statement expressed via this property may serve as a potential input to the service.
| URI: | http://purl.org/vocab/riro/ddl#handlesProperty |
|---|---|
| Label: | handles property |
| Domain | rdfs:Resource |
| Range | rdf:Property |
Definition: [The value of this property is] A SKOS concept scheme understood by the service.
A concept in this scheme may serve as a potential input to the service.
| URI: | http://purl.org/vocab/riro/ddl#handlesConceptsIn |
|---|---|
| Label: | handles concepts in |
| Domain | rdfs:Resource |
| Range | skos:ConceptScheme |
