Hi Paul -
Sure, the spec has an informal suggestion by having a seeAlso to
http://www.w3.org/2003/12/exif/ns/IFD but also foaf:Image would make a lot
of sense.
I look at the spec and i see foaf:Image I see
"Digital images (such as JPEG, PNG, GIF bitmaps, SVG diagrams etc.) are
examples of |Image <http://xmlns.com/foaf/spec/#term_Image>|."
It seems like an Html PictureFrame is not an Image.
But if you mean not just the image file but the HTML page showing an image,
then you could perhaps have a sioc:Item or foaf:Document which has a
sioc:attachment to your foaf:Image or exif:IFD.
At some point I'm starting to feel overwhelmed with too many
predicates. foaf:depicts seems to be highly effective for linking image
files to topics. I guess sioc:attachment might denote a special
relationship between the photo and the frame, but I'm not sure how much
that's really needed. (Something that's HTML aware is going to figure
most of that out.)
That Item could then have associated Comments if you have to have URIs to
fragments in the page?
I suppose I could build something structurally like
<div id="pictureFrame"> ... picture and metdata ... </div>
<div id="comments">
<div id="comment1"> .. a comment .. </div>
</div>
and then type #comments as a MessageBoard but then there's still the
problem of how do I semantically link the comments to the picture that's
in the frame?
With "many ways to say it" I'm left with the concern that I'm going to
spend a lot of time thinking about these issues and then find that only
25% of clients understand my way of saying it. From the viewpoint of
client developers, it's the same trouble -- they're going to need to
pick up junk off the floor and do a lot of inference to make sense of it.
