New DCMI Documnets

Two new documents from the Dublin Core Metadata Imitative. The first involves concepts that relate to RDA. (Although why we are still working on the intellectual foundation when it it nearly ready....) The second provides a model for interoperability on the Semantic Web. The DCMI folks are looking for comments on both.
Guidelines for Dublin Core Application Profiles describes the key components of an application profile and walks the reader through the process of designing a profile. Addressed primarily to a non-technical audience, the guidelines also provide a technical appendix about modeling the metadata interoperably for use in linked data environments. This draft will be revised in response to feedback from readers.

Interoperability Levels for Dublin Core Metadata, published today as a DCMI Working Draft, discusses the modeling choices involved in designing metadata applications for different types of interoperability. At Level 1, applications use data components with shared natural-language definitions. At Level 2, data is based on the formal-semantic model of the W3C Resource Description Framework. At Level 3, data is structured as Description Sets (i.e., as records). At Level 4, data content is subject to a shared set of constraints (as described in a Description Set Profile). Conformance tests and examples are provided for each level. The Working Draft represents work in progress for which the authors seek feedback.
