Re: What happened to semantic tagging?

As I understand the question, the desire is to differentiate between
external resources that have machine readable representations (such as RDF)
and those that are human readable (such as HTML)?  This could previously be
done with foaf:page and skos:related (which would have needed changing
anyway).

I think we still have the mechanics for this in a more consistent fashion:
you could add the media types (using dc:format) to the resource, or a class
to the source resource of the semantic tag to assert that it's a real world
object :)

To extend the example in 4.1:

{
  "id": "http://example.org/anno13",
  "type": "Annotation",
  "body": {
    "type": "SpecificResource",
    "role": "tagging",
    "source": {
      "id": "http://example.org/city1",
      "type": "dbo:City"
  },
  "target": {
    "id": "http://example.org/photo1",
    "type": "Image"
  }
}

Note the importance of using source here rather than id, as the city
doesn't have the role of tagging, it's the specific resource -- the use of
the city in the annotation.

(Editorially, I think the example in 4.1 should have the type:
SpecificResource added to make this clearer)
