[tdwg-tapir] tapir namespace

Hi Roger,
just some quick notes I had in mind when reading your mail.

I really like to have the schema and its documentation behind the namespace. I dont know of a reason why namespaces should point into nothing. 

For the domain I like the idea of namespace.tdwg.org or maybe standards.tdwg.org
The schema file itself would better be named tapir.xsd or something other more descriptive than schema.xsd.

Whether the pure directory http://ns.tdwg.org/tapir/1.0 resolves immediately to the schema or just an index page that links to the schema and further links I dont know. It would be great if its the schema, but then how do you know about the documentation?

Just quick notes as I said.
But I am sure we can change the namespace by February - as long as there arent that many applications existing...

Hi All,

Ricardo and I just discussed namespaces and schema locations without coming to a conclusion. TDWG needs a namespace and schema location policy and we need to reserve a space for these as we put the infrastructure in place.

There are a host of issues to resolve including how we do resources in ontologies, what happens if you try and resolve a namespace URI - do you get a page not found, a generic message saying it is a namespace or specific message or a redirect etc. Should the schema location be the same as the standard location or embedded within it. Also we need to have 'permanent' URLs for standards themselves. Oh and what happens if we change the name of the organisation as people bring up from time to time!

Some of the issues are closely related to GUID stuff so I am hope that we can have a very brief discussion about it at the GUID meeting over a beer and just decide on a load of these things. Many things are more or less arbitrary and a decision just needs to be taken - any decision.

Can you wait till February for a final policy on what the namespace URIs will look like?

I suggest namespaces will be of the form


(note no www as it is not a web thing. We could go for namespaces.tdwg.org/tapir ...)

and schema stuff might be like this:


My big question is: Will the schema change without the standard changing?

There would also be other related to the standard at:


including the normative documentation and a cover page xml document with metadata for the standard.

Does this make sense? I'd appreciate feedback as I am actively working on the specification for all this stuff.
