FOAFCorp/RDF data format

(sorry, missed these messages as I read the list thru the Web; btw Josh,
any chance you could configure YahooGroups to make the message archives
publically visible, so we can point people without YahooGroup logins at
these discussions)

This is a bit long, and perhaps a bit technical for some here. I've copied
the RDFWeb-dev list too, since thats where we discuss the FOAF stuff.

In the foaf rdf version (which I think is a great idea) it makes the
connections (as far as I can tell) algorythmically. I agree with you that
this is something that may be better to actually mannuaklly put into the

I think this for two reasons:
1. speed of display (may not be significant).
2. Accurracy.

What I've done isn't really about display; I just happened to have a neat
tool to hand (http://rdfweb.org/people/damian/RDFAuthor) that made
pictures easy to generate.

GPS, palmpix photo metadata / codepiction idea

(mostly for archival / reference though comments welcomed)

I've just installed PalmOS dev tools and SDK for Linux, and
am experimenting with GPS and PalmPix libraries. My Visor now
has a GPS module; Libby's Palm has a PalmPix photo addon. It'd be nice
if both devices could be plugged into one machine, but that's not doable
with at least our Palms and Visors. Still, Palm+cam and Palm+GPS are both
interesting combos to experiment with.

So I wanted to note an idea for a Palm photo app to use with
RDFWeb. Basically, use the Kodak SDK to make a simple photo-takey program,
with one added gimmick: after taking the photo, you get to add some
metadata, in particular, picking people from the address/contacts book who
appear in the photo(s) you've just taken. This would give us a bunch more
codepiction data for RDFWeb (see [1] for Libby's prototype). Maybe also
some basic categories (I wish all of WordNet would fit on a Palm. Or at
least the noun term hierarchy (which I project into the Web as RDF
classes)). Oh, looks like it does, 4.9m, hmm, cool. Feature bloat already,
and nothing exists yet. http://www.google.com/search?hl=en&q=wordnet+palm+pdb --
something to investigate later. see [palmwn] [rdfwen] for Palm and RDF
WordNet stuff.

There are API calls in the Kodak SDK that allow you to store a pic as
a JPEG, so the photo metadata thing could be a separate app. And the
PalmOS 4.0 SDK comes with a bunch of example code for the address book
(and beaming etc.).

Once the (meta)data is on the handheld, we'd want either to embed it in
the JPEG (presumably tricky given the onboard tools) or perhaps make a
