DCMI is a signatory member of Data Standards United, a collaborative of data standards development organizations that seeks to foster collaboration and alignment standards to support the global education and workforce digital ecosystem.

Shapes

Thu, 24 Jan 2019 00:00:00 +0000

Following a landmark workshop on RDF validation in 2013, two languages have emerged for describing the "shape" of graph structures for the purpose of validating RDF data. The Shape Expressions Language (ShEx) and Shapes Constraint Language (SHACL) provide languages for expressing constraints against which graphs of RDF triples can be compared. These languages support the expression of a Dublin Core™ application profile in a manner that can directly be used for validating metadata based on the profile.

Concept Scheme

Thu, 24 Jan 2019 00:00:00 +0000

Concept Scheme is basically a synonym for Ontology, though concept schemes are most commonly associated with Simple Knowledge Organization System (SKOS), a data model for knowledge organization systems that was designed for maximum semantic simplicity.

Vocabulary

Wed, 23 Jan 2019 00:00:00 +0000

In Semantic Web usage, Vocabulary is a near-synonym for Ontology though "trend is to use the word ontology for more complex, and possibly quite formal collection of terms, whereas vocabulary is used when such strict formalism is not necessarily used or only in a very loose sense." Whatever else they might be called, DCMI Metadata Terms, the AGROVOC concept scheme, and the Bibliographic Ontology (BIBO) are also vocabularies.

Competency Index

Wed, 23 Jan 2019 00:00:00 +0000

A Competency Index is a set of topically arranged assertions of the knowledge, skills, and habits of mind required for professional practice in a given area of practice. DCMI's Linked Data Competency Index, for example, provides an overview, or map, of the Linked Data field both for independent learners who want to learn Linked Data methods and technology, and for professors or trainers who want to design and teach courses on the subject.

W3C

Mon, 07 Jan 2019 00:00:00 +0000

DCMI has been engaged with W3C since the mid 1990s, and "Dublin Core™ metadata" was featured as a usage example in the Resource Description Framework (RDF) Model and Syntax Specification of 1999. DCMI is currently an institutional member of W3C and is thus represented on the W3C Advisory Committee.

Open World Design

Mon, 30 Apr 2018 00:00:00 +0000

Open World Design accepts that information exists in a global context that is evolving in unpredictable ways and avoids assuming that interoperability with future, possibly unanticipated sources can be more than partial. Open World Design stands in contrast to the Closed World Design of traditional IT environments, in which data is carefully controlled, with document formats and database schemas optimized for specific applications. Loosely specified vocabularies such as Dublin Core, when used with generic underlying models such as RDF, provide a good technological basis for Open World Design.

Learning Resources

Mon, 30 Apr 2018 00:00:00 +0000

DCMI supports teachers and learners of modern metadata technologies and practices. An updated Metadata Basics page highlights current trends in descriptive metadata in the style of Dublin Core, which aims at interoperability through using globally shared vocabularies, constrained in application-specific profiles, based on principles of Linked Data. Interested learners can also explore a glossary, a Linked Data Competency Index that enumerates relevant skills to be learned, a guide for users of DCMI metadata terms, occasional webinars, postings on a new DCMI blog, and tutorials at DCMI annual conferences.

In addition to this actively maintained glossary, interested users may wish to consult legacy glossaries from the early years of Dublin Core:
