|Charter:||The objectives of the Architecture Forum are to discuss and develop a model, strategy and roadmap for the practical deployment of Dublin Core metadata using mainstream Web technologies (XML/RDF/XHTML).|
This activity is working on updates to the DCMI Abstract Model (DCAM). The DCAM specifies an abstract syntax for "description sets" (metadata records). Finalized as a DCMI Recommendation in March 2005, the DCMI Abstract Model (DC-AM) expressed the style of metadata that had emerged in the Dublin Core community over the previous decade as formal constructs aligned to the W3C Resource Description Framework (for example, by giving a formal definition to the DC-specific notion of a "vocabulary encoding scheme" and providing for the use of parallel labels in multiple languages). The Abstract Model was designed to bridge the modern paradigm of the unbounded, linked data graph and the more familiar paradigm of the validatable metadata record, providing a foundation for the development of application-independent syntax specifications and constraint languages.
This activity is working on a mapping between schema.org and Dublin Core properties. The Schema.org initiative aims at providing terms that webmasters can embed in Web pages to improve search results. For simplicity of adoption, the initiative is defining all of its terms in its own namespace. Where Schema.org terms overlap with DCMI metadata terms, this Task Group will define and publish formal mappings. The Task Group will work with the maintainers of Schema.RDFS.org—"a complementary effort by people from the Linked Data community to support Schema.org deployment and usage with a special focus on Linked Data"—which has already published a placeholder for future mappings to Dublin Core. The Task Group will identify use cases for the mappings and define a process and workflow to create, publish, and maintain the mappings.
