External Vocabulary References
The description of the terms in the FOAF 'dictionary' often make reference to classes and properties elsewhere. This section of the FOAF specification provides a placeholder reference for any FOAF mention of externally defined terms. For example, sometimes we might say that FOAF property has a domain or range of an externally defined class, or that a FOAF class is a sub-class of an external class, or 'disjoint with' such a class (ie. has no common members). Such claims help fix the intended meaning of FOAF terms in relationship to other 'peer' vocabularies.

- dct:Agent
- Dublin Core's notion of Agent is much like FOAF's; Dublin Core says "A resource that acts or has the power to act.", we say "things that do stuff". As nobody has provided a counter-example of something fitting one definition but not the other, we say here that foaf:Agent stands in an 'equivalent class' relationship to dct:Agent (and vice-versa).
- dct:creator
- The notion of 'creator' in the latest versions of Dublin Core matches FOAF's notion of 'maker'; based on their definitions, every pair of things that are related by one of those properties are also related by the other. We express this by saying that these properties stand in an 'equivalent property' relationship' to one another.

Janos HaitsThis specification describes the FOAF language, defined as a dictionary of named properties and classes using W3C's RDF technology.FOAF is a project devoted to linking people and information using the Web. Regardless of whether information is in people's heads, in physical or digital documents, or in the form of factual data, it can be linked. FOAF integrates three kinds of network: social networks of human collaboration, friendship and association; representational networks that describe a simplified view of a cartoon universe in factual terms, and information networks that use Web-based linking to share independently published descriptions of this inter-connected world. FOAF does not compete with socially-oriented Web sites; rather it provides an approach in which different sites can tell different parts of the larger story, and by which users can retain some control over their information in a non-proprietary format.

By using RDF, FOAF gains a powerful extensibility mechanism, allowing FOAF-based descriptions can be mixed with claims made in any other RDF vocabulary

To a computer, the Web is a flat, boring world, devoid of meaning. This is a pity, as in fact documents on the Web describe real objects and imaginary concepts, and give particular relationships between them. For example, a document might describe a person. The title document to a house describes a house and also the ownership relation with a person. Adding semantics to the Web involves two things: allowing documents which have information in machine-readable forms, and allowing links to be created with relationship values. Only when we have this extra level of semantics will we be able to use computer power to help us exploit the information to a greater extent than our own reading.

Gary BurgeThe FOAF project is based around the use of machine readable Web homepages for people, groups, companies and other kinds of thing. To achieve this we use the "FOAF vocabulary" to provide a collection of basic terms that can be used in these Web pages. At
