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 page, a Linked Data Competency Index that enumerates relevant skills to be learned, a guide for users of DCMI metadata terms, occasional webinars and tutorials at DCMI annual conferences.
