Thank you all! :-)
ISO 15836-2 has been published on the basis of DCMI Metadata Terms
DCMI is pleased to announce the publication by the International Standards Organization [ISO announcement] of ISO 15836-2, "Information and documentation — The Dublin Core metadata element set — Part 2: DCMI Properties and classes" [ISO 15836-2]]. In parallel, a revised "DCMI Metadata Terms" [*] document has been published on the DCMI website.
The original "Dublin Core Metadata Element Set" of fifteen elements, originally designed in the late 1990s to support the generic interoperability of resource descriptions across languages and disciplines, was first published as an ISO standard in 2003 and remains available today in a recently updated version as ISO 15836 Part 1 [*LINK].
ISO 15836-2 extends the original set of fifteen "core" properties with forty properties and twenty classes usable to improve the precision and expressiveness of descriptions based on Dublin Core. ISO 15836 Part 2 also specifies the URIs (Uniform Resource Identifiers) by which its terms are referenced in Linked Open Data.
In preparing ISO 15836-2, the DCMI Usage Board has enriched the metadata terms with best practice usage examples and clarifications in response to comments and requests from the ISO committee "TC 46/SC 4/WG 16 Dublin Core" and from the P members of TC 46/SC 4. The formal range constraints for some of the properties have been relaxed in response to lessons learned from many years of implementation practice. The new ISO 15836-2 standard is truly the result of a productive collaboration between DCMI and the international standards community.
