innovation in metadata design, implementation & best practices

About the Dublin Core Metadata Initiative

The Dublin Core Metadata Initiative, or "DCMI", is an open organization supporting innovation in metadata design and best practices across the metadata ecology. DCMI's activities include work on architecture and modeling, discussions and collaborative work in DCMI Communities and DCMI Task Groups, global conferences, meetings and workshops, and educational efforts to promote widespread acceptance of metadata standards and best practices.

DCMI maintains a number of formal and informal liaisons and relationships with standards bodies and other metadata organizations.

The Dublin Core Metadata Initiative (DCMI) is an open organization managed as a project of ASIS&T, a U.S. 501(c)(3) nonprofit under the U.S. Internal Revenue Code.

Membership Programs

DCMI Members support the work of DCMI, participate in its governance, and receive benefits such as access to content, discounts for events, and visibility. DCMI is an organization committed to the development and open availability of resources that support a healthy global metadata ecosystem. Annual membership dues by DCMI members play a significant role in ensuring that DCMI continues to advance this commitment to support innovation in metadata design and best practice. Regional Members and Institutional Members help shape DCMI by: (1) bringing their institutional perspectives to the work agenda of the Initiative through active participation on the governing Oversight Committee; and (2) supporting the efforts of an international community of volunteer metadata experts. Supporting Members (private-sector companies and foundations) and Individual Members (interested individuals and students) support DCMI and enjoy membership benefits without formal duties related to governance.

The work of DCMI requires dedicated, paid effort funded through the annual contributions of DCMI members. These paid efforts include:

The Community

Web site, policies, software, logo, banner

The Dublin Core Metadata Initiative Web Site is the major public entry point and formal repository for DCMI documentation, including current and past activities and meetings.

DCMI seeks to attract the individuals and organizations worldwide interested in collaborating on metadata standards as well as the design and development of enabling metadata technologies. To this end, the DCMI has established the following policies.

Over the years, DCMI has developed several software applications to generate and manage machine-readable representations of metadata: a metadata registry application (in Full and Lite versions), a Vocabulary Management Tool, and a tool for extracting structured representations of application profiles from MoinMoin wiki pages. The source code for these software applications is freely available for interested users under DCMI open source licenses.

The DCMI logo consists of a central sphere, representing the core of the Initiative. The inner surrounding spheres represent the original 15 core data elements available in the DCMI Metadata Element Set (ISO standard 15836). The outer spheres represent an interpreted and extended element set.
