"Tag" metaphor and "Tag User Interface"

Hi all,

  most ontologies I have seen use some namespace, then a hash or slash
  and then more or less englisch terms. These last parts look like
  tags, the first part - the namespace - is then the context.

  I am right now designing a wiki system that lets the user enter RDF
  statements in a notation similar to
    tag   tag   "a longer tag"
     (s)   (p)       (o)

  I use
  "any text" "other text" "more text"
  and upon page save in the wiki each string is given a unique uri.
  This creates rdf like this:
  _:1 rdf:value "any text"
  _:1 rdf:value "other text"
  _:1 rdf:value "more text"
  _:1 _:2 _:3

  If a string is the value of two or more uris, the user is prompted
  to choose among the available uris. I think this could lead to a
  very easy to use user interface without loosing "uri-precision" in
  disambiguating terms. Probably such string-to-uri service should  be a REST-ful
  webservice...

  Ok, that's I all, I just wanted to make the point that tagging not
  neceassaryly means ambiguos data.

Regards,

  Max
