[topicmapmail] PSIs?

| I would be publishing a specification that overlaps a domain owned
| by somebody else. The W3C may wish to publish a PSI set. PSIs are
| very likely to be considered IP, and I think that even though we're
| new to this territory, my guess is that it's a *very bad* idea for
| me to publish PSIs using their URLs.

I agree it is bad for you to create URIs in their domain, but you
wouldn't be doing that in this case. OWL already uses the same URIs,
so you would just be following OWLs lead. I think it's much better for
us to use the same URIs as the W3C for what is certainly the same
subjects.

| What I'm trying to say is that if I download datatypes.xtm and load
| it from a local file and merge it with one of my own topic maps that
| use the PSIs defined by you they won't merge because the PSIs
| defined by you won't actually be in datatypes.xtm.

| Yes it will. Downloaded or on the web, the datatypes.xtm document
| has a base URL that is identical, [...]

The base URL given by xml:base doesn't affect the resolution of the
IDs of <topic> elements. Officially this XTM issue isn't resolved yet,
but I don't see how it can be resolved any other way.

Proposed resolution in:

This will be discussed at the SC34 meeting in London, btw.

| If I have this much difficulty I hate to think what a newbie is
| going to suffer in trying to publish PSIs.

The people who published <URL: http://psi.uio.no > were newbies and
had no problems at all. They followed the recommendations, though.
