New RDFWeb logo concept

I threw together a little logo in OmniGraffle, trying to get some more
color. The color looks pretty bad in all except the PNG version for some
reason. It's easy to twiddle with -- send me suggestions:

http://swartzfam.com/aaron/rdfweb/rdfweb.jpg

and the OmniGraffle XML source:

Enjoy,

new url for java rdfweb


http://swordfish.rdfweb.org/rweb/who

to make it more consistent with the perl version. 

I can't remember if I mentionned that I also implemented a form of
security for the information, namely, if you tell me that you wrote the
information about you, then it becomes 'secure' information within the
system. You can view all info or just secure info about knows and
personal information (but not rss channels, calendar or documents as
yet). This isn't excatly a scaleable approach, but the fact the we can
tag individual triples with information is a first step. This was
implemeted using Danbri's idea of having a separate database table for
provenance information, and for speed, using the stanford hashing of
triples, which has its own disadvantages.

Re: new url for java rdfweb


http://swordfish.rdfweb.org/rweb/who 

now shows personal info, people known and documents (not RSS channels,
or too slow). Also the people section links back to people who say they
know the person as well as people the person knows. You probably need to
select 'show all information' to see this info, since it's unlikely that
people will state that other people know them.

I also found a page I did a while back for generating webwho files -
just a simple webform generator. Something like Dan's shopping basket
would be better, but this is something anyway.

http://swordfish.rdfweb.org/rweb/aboutme

can also make a plea for people to alter their webwho files so that
relations between people are 'knows' and not any more detailed than
that? I think we decided that this was the best cuorse of action, and it
makes querying faster, as well as being less personal (I used a webwho
file to try to explain RDF to jonathan robie, who was quite shocked at
the level of information we were making public).

You seem to have fallen into the common fallacy that the URI itself (and
thus the publisher of the URI) is the best source of information about the
URI. This isn't true -- the publisher is only the best source of information
about what the URI is. Everything else is up in the air. Let me give an
example:

:WackyWidgets :governmentSafetyRating :Excellent .

WackyWidgets is not the best source of information for this information.
Instead, the Government rating department is. WackyWidgets is likely to lie
about this kind of thing.

The net effect for your page is that I'm liable to claim that I'm a
contributor to all sorts of things, but the fact is that that information is
not "secure". A better thing to trust is the document itself, which is
unlikely to contain RDF at this point.

A further point is that I can lie about what my name is, etc. But that's not
too likely in this environment.

I'd agree that for certain types of resources this is a more useful
source of information, particularly books, plumbers, music,
products. But I'd contend that one important distinguishable source of
information about people is they themselves, and that the distinction
between information from this source and others sources (their friends,
enemies) is important to make in the user intereface.

On problem is that rdfweb is capable of being many things - a CV for
example vs a substitute for a search on google. I think the provenance
of the information on RDFweb is a part of the quality of the content
there (this is a lesson from the subject gateways community), and one of
our aims should be to make this meta-meta information available. The
challenge is to program heuristics for presenting this to the users in a
userful and clear manner. Perhaps 'secure' is not an appropraite word
though.

p.s. the nascent (meta) discussion on rdf-logic seems relevant here...

Re: Re: new url for java rdfweb

I think the only error is the word 'secure'; perhaps 'self-proclaimed'
would be a better way of putting it? Nothing to do with URIs etc...

BTW does anyone know Java code for checking PGP signuatures?

Hi,

After reading Sun's white paper[1] on JXTA Search, it appears
that they are interested in integrating their own peer-to-peer
search network with RDF (see the last page). Currently they have
defined their own 'queryspace' XML syntax, which seems pretty
pointless when RDF is already available.

What's nice is that Sun has come up with a way for metadata producers
to define what kinds of information they specialise in, which might be
instructional in the organisation of the semantic web. This could be a
nice opportunity for getting RDF used in the wild, if the hype of
JXTA is to be believed.

Anyone from Sun on this list?
