[Tdwg-tag] A very simple question stated again.

This 'semantic tagging' is something that may be useful in some
situations. The two examples I have been thinking about are:
1. Marking up existing schemas as you suggest. This might make it
easier to transform between systems but would need investigating.
We could also map the namespaces of the elements in instance
documents and do it that way.
2. Marking up regular text in taxonomic literature could be done by
extending XHTML. We could simply extend <span> and <div> tags to
have a tdwg="" attribute that contains the URI or URN of the core
class of thing between the tags. Regular browsers and text
processors would ignore the additional attribute but could be
extended to handle it. Simple applications could be written in
JavaScript to extend browser functionality to give term expansion,
associated searching etc. Data could be extracted with XSLT etc...
Some clever person might even extend DreamWeaver or another editor
to support authoring of the tagging but regular taxonomists who
are using word processors at the moment. (This is a fantasy
example and not a concrete suggestion of doing it this way!)
I think the point is that most of these technologies overlap and we are
probably not talking using 100% of anything in a solution model.
All the best,
Roger
