  data as well as combining it with other
  vocabularies

Publishing FOAF Data

• Create an RDF document containing FOAF terms and
  copy it to the Web ? FOAF file URL
• Link the new information into the existing web of
  FOAF data
• through foafknows linking to other peoples
  FOAF data via rdfsseeAlso tag
• through the FOAF Bulletin Board (i.e. a FOAF
  directory)
• through auto-discovery linking to a FOAF document
  from an HTML page using the link element
• ? highly decentralised FOAF data neither with
  full linkage nor defined location on the Web

FOAF Applications

• FOAF Explorer
• FOAFnaut SVG Application
• FOAF Filer
• Social Networking (Web 2.0)

Enumservice foaf

• Links FOAF data to E.164 number
• Allows immediate detection of FOAF file URL
• Allows combination of FOAF and ENUM spidering
  enhancing the search results assuming FOAF and
  ENUM to be widely deployed ... -)
• Allows detection of a huge variety of a persons
  metadata by means of that persons phone number
• Introduces ENUM to the Semantic Web
