How can you forget about Content Labels? I thought I already had you


Seriously, we have a vocabulary for accessibility, ICRA have one for, er,
ICRA descriptors. Is this where you would see a definition of Content
Labels, or detail about the vocabulary?

Hi Guys,

perhaps read the wiki-page in parallel to this email thread.
DOAP, FOAF, etc are all mentioned there already,

Benjamin, Ivan, you are free to edit the wiki page,
just change/adapt it so that it reflects your approach, please start
(no edits so far,
this is a wiki, free speech, last change wins, anything goes, like

I see two things to face, first:
Describing Information items as such, such as tools, websites, 
presentaitons, tutorials. This should be done using RSS 1.0, and in some 
cases when needed extended using DOAP, foaf, etc. This is pretty 
straightforward, please review and update this site until you agree:

Not sure about the RSS design decision, it pretty much restricts
the resource types to documents, so we can't really use it as an
"umbrella" spec. My 2 highly redundant cents:
- I found DOAP to work fine for most things software, DCMI provides a 
  number of handy resource type URIs[1] which could be used to augment
  doap:Version resources (e.g. dctype:Collection, dctype:Dataset,
  dctype:InteractiveResource, dctype:Service), or owl:Ontology for
  projects that produce vocabularies (e.g. the FOAF project)

That was partly already there, 
please edit the wiki page so that it reflects your exact ideas, but I think
the current version already is like you say here.

- tags (skos:subject, or dc:subject) for more specific stuff (personal
  preference: the more fine-grained skos options)

ok, one more for SKOS

- Danny's review vocab[2] for ratings/reviews

please add this to the wiki page!

- a combination of the two rdf/iCal specs[3][4] (with and without
  timezone-datatyped timestamps) for events

they are rather buggy and not clear which one to use, but I would go for the
simpler (not-timezone-as-datatype-one).

Quick thoughts: I see the motivation re. reuse, but rather than trying 
to use solely RSS 1.0 for the items, it might be better to use more 
precise terms where they exist, as_well_as the RSS terms, e.g. 

 <http://example.org/doc> <http://example.org/doc> a rss:item; a
foaf:Document . 

I also thought about this, but if you require from all participants to do
that, it sucks.
Why should anyone annotate two types if one is enough? This is the format we
expect external data to be in,
inference should add the additional triples.

For the taxo stuff, SKOS sounds a very good idea generally, though I 
wouldn't be surprised if there were existing vocabs that could be used 
for things like "tutorial" etc. 
I'll cc Ian, he hangs around libraries... 

It might also be worth considering (perhaps redundantly again) the Tag 
Ontology at 

SKOS covers this and more, so would rather use skos.
