Dublin Core

"The Dublin Core™ Metadata Initiative (DCMI) supports innovation in metadata design and best practices. DCMI is supported by its members and is a project of ASIS&T. For more than twenty years, the DCMI community has developed and curated Dublin Core Specifications. More recently, DCMI has become recognised as a trusted steward of metadata vocabularies, concept schemes and other metadata artefacts, and has taken responsibility for other community-created specifications" (Dublin Core 2021)
