OK I'm off to France (W3C/Europe) for the week, from tommorrow.
Here's a quick catchup of FOAF stuff as the weekend runs out of steam...
- vocabulary status annotations
FOAF vocabulary now contains assertions which use the
previously discussed. Almost everything is flagged as 'testing',
with a fair few 'unstable' properties, notably the bulk of the
- vocabulary changes
new classes, 'foaf:Agent' and 'foaf:Group'; the former because
various properties feel over-constrained with a domain of 'Person',
the latter because several of us are experimenting with variants of
it, and there is a clear need to do something. Both are flagged as
'unstable'. Agent is a super-class of Person, Organisation, Group.
foaf:Group will need some attention to get right.
http://rdfweb.org/issues/show_bug.cgi?id=8 is the bugtracker entry
new property, 'foaf:based_near'. A stopgap to scratch an itch that
has been bothering several of us, until something along the lines of a
vocab like http://esw.w3.org/topic/GeoOnion comes along. The
foaf:based_near property relates geo:SpatialThing instances to
geo:Point locations, ie. elaborates on the minimalistic geo / wgs_84
vocabulary we provide at W3C, http://www.w3.org/2003/01/geo/
Also flagged as 'unstable', largely to reflect the vagueness of
the notion of 'near'. The new property is documented in the wiki
at http://rdfweb.org/topic/UsingBasedNear as well (already!) as
(which now also covers nearestAirport markup).
- weblog burblings
A couple of technical documentation posts this week, on
'foaf contradictions' and 'identifying things in foaf'. Also a few
news-roundup posts, re Japanese docs, Semaview's paper + foaf browser,
digiboy's foaf creation tool + auto-discovery evangelism,
foafbot/dashboard, and Dan Hon's 'Handshake' UI screenshots.
- website re-organisation
OK, some new news. It is becoming clear that FOAF will for some time
have a stronger identity than the broader semweb hacker stuff which
rdfweb.org as a developer site provides. I'm happy with the way
the rdfweb.org site is shaping up as a bunch of tools to support folk
who are fairly interested / involved in all this stuff, and who are
not scared by words such as 'xml'. But there is a need for more
user-facing materials, and (I've come to think) for a website with
the letters 'foaf' in it's domain name.
So... over the weekend I've made a start on migrating the FOAF 'home
page' to a separate FOAF site, which I'll at some point redirect the
http://rdfweb.org/foaf/ URL to. The new site is a single page job for
now, http://www.foaf-project.org/ and which currently consists of little more than a one sentence summary, a very big version of Ian Davis's cute
FOAF logo, and some quick links to... useful stuff. I don't expect this
to be a big site, most things can happily stay at rdfweb.org but a
few FOAF-centric pages there could make things easier for people new to
The main thing I think to do initially is create a page or few which
explains those funny little FOAF icons to the non-geek interested
party, ie. to answer the 'wtf is this FOAF thing?!' question in a way
that assumes less technical obsessiveness than we have to date.
Work in progress, but probably worth switching over to in the next
week or so, given that the current FOAF homepage is pretty crap too.
I thought I'd share where I'm up to, rather than go 'ta da' with a
finished product... Feel free to write
<a href="http://www.foaf-project.org/">FOAF</a> instead of citing
http://rdfweb.org/foaf/ already, I'll clear up remaining navigation
confusion when I'm back from France.
- foafcorp logo hacking
Playing around with the foaf logo thing in Gimp, an idea for a foafcorp
...in general I think this is a fun graphic (thanks Ian!) as it can
be goofed around with in various ways while keeping the same basic
look. Might be worth thinking about how the colours compare to
those used in foafnaut and other foaf stuff.... (Liz?)
I've started re-running my FOAF harvester. It doesn't find as much
data as it should, I think due to bugs in the Ruby Rdf parser, but I've
just launched a mailing list for that effort so hopefully it'll be more
That's about it. Oh, one more thing, I have a beta testers account on
TypePad, see my test site at http://foaf.typepad.com/ and have to say
I'm really impressed with what they've been up to, not just the FOAF
stuff (which is very exciting) but the whole usability thing.
