Hi Rob,

This tentatively looks good. With regards to text, we'd likely to have to use the extremely abstract schema:CreativeWork class. We'd might want to further clarify using the predicate-object combo of "schema:genre schema:Text" to make an assertion about the Creative Work. This does seem more modern than Dublin Core but I do wonder if it is actually better.

Regards,

Jacob

As discussed on the call on Wednesday, we should make a change to the list of types for body and target at least to replace Image with StillImage.  A further suggestion was that we should consider schema.org<http://schema.org> classes as more modern and likely to be better integrated with other systems.

It would also give us easy classes for Code, SoftwareApplication, Game, WebPage... but there isn't one (that I can find) for generic Textual content.  schema:Text is a datatype, rather than a class for resources.

Thus the list maps currently as:

Dataset            -->  schema:Dataset
StillImage         -->  schema:ImageObject
MovingImage   -->  schema:VideoObject
Sound              -->  schema:AudioObject
Text                 -->   :(

We could be more explicit with our typing for Text:

oa:Tag  when the body is a tag.
oa:SemanticTag when it's a semantic tag
schema:Comment when it's a comment [w/ oa:commenting]
schema:Review when the body is a review

schema:WebPage when the body/target is a full webpage
schema:WebPageElement when the body/target is part of a page

And then leave anything beyond those to further communities to define?  Is there anything in our current set of use cases that would fall out side of the above?

Thanks!

Rob
