Comments to “SE Free text tagging a Image”

Comments to “SE Free text tagging a Image” at
www.w3.org/community/openannotation/wiki/SE_Free_text_tagging_a_Image (and
the corresponding section)



About the example:

The title should be “SE Free text tagging an Image”, the “n” at “an” is
missing



The description of the example says “A Tag is a label attached to someone
or something for identification or other information.” I think a comment
could also be used for “other information” so maybe a better description is
required? Maybe we can use Wikipedia definition at
http://en.wikipedia.org/wiki/Tag_(metadata)



In the RDF we have <http://alturl.com/wxidq> a dt:Image. Does dt stand for
Dublin Core Terms? If it does, then we should use the namespace defined in
the Introduction, i.e., dcterms. If it does not, then we should include
that namespace in the Introduction or at least in the example



A nice variation including the selection of a particular feature within the
protein would be nice. That would probably include selectors and specific
resources. However, the required selector would be tricky as it is not a
portion of the image but a portion of the protein region represented by the
image. Maybe that this is a 3D structure and just working with selected
pixels in the image, or some kind of freehand selection? I think this would
be a nice example. Ideas/suggestions on how to model the selection are
welcome.



About the section:

We have a section “2.1.3 Tags and Semantic Tags” and there we introduce the
class oa:Tag. However, we do not use it in this example; I think it is
missing.

>From the description in the section, it seems that semantic tags are those
tags corresponding to URIs? I do not think that is always the case. “
http://dbpedia.org/resource/Paris” does correspond to a semantic entity but
“http://wikipedia.org/Paris/”  does not. I think that for semantic tags
only URIs corresponding to semantic entities should be use, any other
thoughts about it?


One question not necessarily related to tags. Could I use annotations to
say that a 3D version of that image can be retrieved from “PDB link” in
format “XXX”? If yes, how could that being expressed in OA? In general, the
question is how to express links to other resources with annotations?
