6. Conformance
Conformance to this standard is discussed in 6.1 through 6.5.
In this standard, “shall” is to be interpreted as a requirement; “shall not” is to be interpreted as a prohibition.
6.1 Conforming aggregation instances
A conforming aggregation instance shall be an instance of an aggregation format that has been modeled or described in terms of the core ontology (via a mapping or otherwise) following the intentions of the core ontology as expressed in Clause 7, Clause 8, and Clause 9 of this standard.
6.2 Conforming bindings
Conforming bindings of the core ontology:
Shall conform to the requirements of Clause 7, Clause 8, and Clause 9 of this standard.
— If the binding technology language supports Uniform Resource Identifiers (URIs), then it shall use the same URIs as those in the Terse RDF Triple Language (Turtle) representation referenced in Annex H of this standard.
If the binding technology language supports URIs and the binding contains extensions to the core ontology (sec 6.4), then identifiers for the extensions shall be defined in another namespace.
6.3 Conforming mappings
Conforming mappings for new aggregation formats may be defined. A conforming mapping shall be an ontology of an aggregation format expressed in terms of the core ontology defined in Clause 7, Clause 8, and Clause 9 of this standard. Conformance requirements for mappings include the following:
When a concept is already expressed as a class or property in the core ontology, the mapping shall use the identifiers for that class or property as defined in the core ontology.
— When a concept is not already expressed as a class or property in the core ontology, the mapping may extend the core ontology by adding a new class or property and by defining a new identifier. The new identifier shall not be used to identify a concept that already exists in the core ontology.
6.4 Conforming extensions of the core ontology
When a concept relating to interpreting externalized representations of digital aggregations is not already expressed as a class or property in the core ontology, a mapping may extend the core ontology. The core ontology may be extended by adding a new class or property and by defining a new identifier in a new ontology. The new identifier shall not be used to identify a concept that already exists in the core ontology. Bindings for conforming extensions shall conform to the requirements in 6.2.
NOTE—Concepts relating to interpreting externalized representations of digital aggregations should be defined as conforming extensions to the core ontology. Other concepts may be represented by other vocabularies or ontologics and combined with the core ontology using standard Semantic Web practices.
6.5 Conforming transforming implementations
A conforming transforming implementation shall implement a transformation from an aggregation format to the core ontology and its identifiers or from the core ontology and its identifiers to an aggregation format by using a model following the intention of the core ontology as defined in classes in Clause 7, Clause 8, and Clause 9 of this standard.AS 1484.13.1 pdf download.
