httpxmlnscomfoaf01

httpxmlnscomfoaf01 refers to the FOAF (Friend of a Friend) vocabulary namespace commonly written as http://xmlns.com/foaf/0.1/. This URI denotes the set of terms used to describe people, their activities, and their social connections in the context of the Semantic Web. The FOAF vocabulary is designed to enable interoperable, machine-readable representations of profiles and relationships across different sites and data sources.

The FOAF vocabulary was introduced in the early 2000s by Libby Miller and Dan Brickley as a way to model social networks and profiles in RDF. The 0.1 version provides a compact set of classes and properties for describing agents, organizations, and documents, with a focus on human-readable attributes and links between people. While newer refinements exist, the 0.1 namespace remains a commonly cited entry point for legacy data and simple FOAF deployments.

Core terms associated with the http://xmlns.com/foaf/0.1/ namespace include foaf:Person and foaf:Agent as classes, and foaf:name, foaf:mbox, foaf:homepage, and foaf:knows as properties. These terms enable expressing a person’s name, contact details, online presence, and social connections, respectively. The vocabulary is used in RDF serializations such as RDF/XML and Turtle, and it has influenced subsequent web ontologies that describe people and social graphs.

In practice, a FOAF document describes a subject as a foaf:Person with properties that convey identity and relationships, enabling cross-site data linking and profile aggregation while preserving a lightweight, human-readable model of social information.
