Status of Document: This is a DCMI Recommended Resource
Description of Document: This agreement outlines specific measures to be undertaken in cooperation between DCMI and the FOAF Project -- measures aimed primarily at reinforcing the long-term viability of the FOAF Vocabulary by addressing the risks inherent with having a single point of failure. The two organizations also see this cooperation as an opportunity for better integrating their vocabularies with alignments -- mutually declared mappings between semantically overlapping terms -- and for promoting the documentation of best-practice usage patterns in which the two vocabularies are used in combination.

The Dublin Core Metadata Initiative (DCMI) is an open organization, incorporated in Singapore as a public, not-for-profit Company limited by Guarantee (registration number 200823602C), engaged in the development of interoperable metadata standards that support a broad range of purposes and business models. DCMI is the maintenance organization for the vocabulary DCMI Metadata Terms.

The Friend of a Friend (FOAF) Project aims at creating a Web of machine-readable pages describing people, the links between them, and the things they create and do, using an open, decentralized technology for connecting social Web sites and the people they describe. The FOAF Project is the maintenance organization for the FOAF Vocabulary.

Preamble on shared goals

The FOAF Vocabulary and DCMI Metadata Terms are often used together in applications, and both are consistently listed among the top vocabularies in the Linked Data space. As organizations, DCMI and the FOAF Project share a common interest in improving resource discovery across the boundaries of information silos on the Web. They share also share a common concern for balancing centralization and decentralization by encouraging the stabilization of third-party extensions and companion vocabularies that enhance the usefulness of the vocabularies they maintain.

This agreement outlines specific measures to be undertaken in cooperation between DCMI and the FOAF Project -- measures aimed primarily at reinforcing the long-term viability of the FOAF Vocabulary by addressing the risks inherent with having a single point of failure. The two organizations also see this cooperation as an opportunity for better integrating their vocabularies with alignments -- mutually declared mappings between semantically overlapping terms -- and for promoting the documentation of best-practice usage patterns in which the two vocabularies are used in combination.

Both organizations believe that arrangements of mutual support and cooperation among vocabulary maintainers such as this agreement can improve the long-term viability of RDF vocabularies in all niches of the Semantic Web ecosystem -- from vocabularies maintained by small, agile, time-limited projects or grass-roots initiatives to vocabularies maintained by stable cultural memory organizations -- and offer this agreement as a potential template for others.
