[topicmapmail] tagging vs topics

| For some reason, in-text tagging is not so widely used. I am not
| sure if topic map engines even handle mixed formats with XTM and
| some other tags.

XTM isn't really designed for mixing with other formats, and even if
you did a topic map engine would have no idea what the non-XTM markup
meant, so it's hard to see what this would achieve.

It's better to keep the XML as ordinary XML, and keep the topic map
separate from it. Then you can use XML tools for the XML and topic map
tools for the topic map.
 
| Popular option for tagging is to have a separate metadata (topic
| map) file, which only refers (via subjectIndicatorRef and
| resourceRef XTM elements) to the article. If your material should be
| in XML, I think you can use XPath references to the point of that
| topic in the article.

Yep. Or you could create IDs. Either way it will work.
 
| Some metadata markup "standards" are (other than XTM):
| - SHOE standard for HTML docs (Simple Hypertext Ontology
| Extensions), puts the metadata at the beginning of the file

This is good input to a topic map harvesting tool, and makes good
sense to use.

| - RDF(S) family (RDF, DAML etc.), a generic resource description
| language.

You could use RDF, but if you're going to work with topic maps might
as well use topic maps instead.
