DCMI Liaisons and Relations

The Dublin Core Metadata Initiative (DCMI) has relationships with the following standards organizations and initiatives:


ISO (International Organization for Standardization) & NISO (North American Information Standardization Organization)

ISO: TC 46/SC 4: ISO 15836
NISO: Z39.85

  1. The "Dublin Core Metadata Element Set" as NISO and ISO standards
  2. The ratification and recognition of the original, fifteen-element Dublin Core as an international standard began with its publication in 2001 by the US National Standards Institute and the National Information Standards Organization as the American standard ANSI/NISO Z39.85-2001, "The Dublin Core Metadata Element Set". This paved the way for the publication by the International Organization for Standardization, two years later, of ISO Standard 15836-2003. In 2007, a routine five-year review of Z39.85 led to the publication of the slightly revised and still-valid ANSI/NISO standard Z39.85-2007, in turn paving the way for the revised ISO standard 15836:2009.

    The year 2012 marks the fifth anniversary of Z39.85-2007, once again triggering a five-year review. Over the coming months, DCMI will be asked by NISO to submit a revised text of the standard for review and comment by its member organizations. After responding to comments and making any necessary adjustments Z39.85 will, it is hoped, be re-published as a revised ANSI/NISO standard. When this has been completed, as in previous review cycles, attention will turn to a five-year review of the ISO standard.

  3. Ongoing liaison with NISO and ISO
  4. Starting in 2001, and in parallel to these standardization efforts, DCMI as an organization has been registered as a liaison to various ISO committees:

    1. To JTC 1/SC 29/WG 11 (Joint Technical Committee 1, Sub-Committee 29, Working Group 11), "Coding of moving pictures and audio", known for its MPEG standard, DCMI is a Category C liaison organization.

    2. DCMI is likewise a Category C liaison to JTC 1/SC 32/WG 2, "MetaData".

    3. In February 2012, DCMI was granted Category A liaison status with ISO/TC 46/SC 4, "Information and documentation / Technical interoperability" -- a technical committee that covers metadata standards. Category A liaisons are organizations that make an "effective contribution to the work of the technical committee". They are are given access to documentation, invited to meetings, and may nominate experts to participate in working groups. At present, the other fourteen liaison organizations to TC 46 are: CE, CIDOC, EASE, EC, IAEA, IFSE, ISSN International Center, Infoterm, OECD, UNCTAD, UNECE, UNESCO, WIPO, and WMO.

    As a Category A liaison organisation, DCMI will be able to follow a fast-track standardization procedure, whereby existing standards are introduced into the ISO process starting at the level of Draft International Standard, by-passing the lengthier steps required for New Work Items and Committee Drafts.

    Leif Andresen of the Danish Agency for Culture, DCMI's representative both to NISO and to ISO TC46/SC4, serves as the conduit for communication with these standards organizations regarding the five-year reviews and, potentially, for any additional standardization work that DCMI may wish to undertake and will keep the Dublin Core community informed about processes, deadlines, and other relevant developments.

CC:DA (Committee on Cataloging: Description & Access)

DCMI has a liaison with the Committee on Cataloging: Description & Access, the body within the American Library Association responsible for developing official ALA positions on additions to and revisions to RDA: Resource Description and Access.

Liaison Representative: Diane Hillmann - metadata.maven@gmail.com


The Friend of a Friend (FOAF) Project

DCMI has a liaison with the Friend of a Friend (FOAF) Project, a project which aims at "creating a Web of machine-readable pages describing people, the links between them and the things they create and do" and for maintaining the FOAF Vocabulary Specification. In May 2011, DCMI and the FOAF Project agreed to tighten the alignment between DCMI Metadata Terms and the FOAF Vocabulary -- specifications often used together in applications, especially in the Linked Data space. The DCMI-FOAF agreement includes a commitment to share preservation and long-term maintenance responsibilities for FOAF's xmlns.com domain name.

IETF (Internet Engineering Task Force)

In August 2007, a new IETF RFC, RFC5013: The Dublin Core Metadata Element Set was published to replace IETF RFC2413: Dublin Core Metadata for Resource Discovery of September 1998.

Liaison Representative: John Kunze - jak@ucop.edu


NISO/DCMI Joint Webinar Partnership

The National Information Standards Organization (NISO) and the Dublin Core Metadata Initiative (DCMI) are continuing their educational partnership in 2012 with four joint webinars on topics related to metadata, interoperability, and semantic linking. See details of the Webinars at the NISO Web site.
