Re: [ANN] xOperator 0.1 (Semantic XMPP / Jabber Agent)

Hello all,

I think, that xOperator is an amazing project, but I have an idea. Where are
different useful projects already exist for personal usage (ala semantic
desktop vision): Zotero [1], DBin [2], Gnowsis [3], Soprano (NEPOMUK
reference implementation for KDE) [4] and others. But it's impossible to use
RDF data from one application in another. We doesn't have something like a
'semantic system' for RDF by analogy with the file system for ordinal files.

We'll take a lot of benefits if we start to use a 'semantic system' through
a language, RDF storage and/or platform independent interface. We have
examples of such attempts: semap's HTTP protocol [5] (doesn't independent
from the Sesame RDF storage), Soprano API [6] (doesn't have a language and
platform independence). I have just developed my own RESTful API from
scratch [7] too. On top of such semantic systems we'll can to implement
numerous useful semantic agents and information from one agent will be
available in another immediately. It's like the old WinFS [8] idea in a new
RDF-based point of view ;)

NEPOMUK [9] is a great European initiative to implement the semantic desktop
vision, but it doesn't try to create a general semantic system. What do you
think about it? Do you know similar ideas or projects?
