I was speaking theoretically - I don't have a practical example but I can imagine automatically building annotations from other sources, with values that we may not necessarily want to show on a wiki page.

For example, aliases or mappings of a page name to internal IDs in several databases. You would need this type of annotation to do further queries and you would currently implement that with 'silent' annotations somewhere on the page (or in a template).

It could be useful to move them in a related page in a separate namespace to both avoid confusing casual editors of the page and prevent manual edits of these annotations.

Hi,

I'm confused about a few things - John:

- what do you mean by "logical properties" and "presentation properties"?
- what's a "spo statement"?

And Laurent - what would be an example of a "complex, arcane annotation"?

Hmm you raise some interesting possibilitieshowever it seems that a generic capability to store spo triples about any wikipage is much more ambitious than what I'm suggesting. In my proposal, queries do not change whatsoever; howebver the SH approachwould involve compound queries, first of the subject-page's own triples, and then of the other-namespace-page's set of triples to identify thosewhose subject is the subject-page. That said, your suggestion is an absoluterequirement for instance in the legal arena whose documents have nothing BUT spo statements (albeit couched in lovely legalese) that is of course, if one is not interested in documents being the result of a massive number of cascading transclusions!!! Thanks for your thoughts. John

I can see a use for this sort of thing with any automated annotation application.

It would be nice to have a way to store complex, arcane annotations without overloading the wiki page itself.

It doesn't have to be in the talk page, maybe a separate name space altogether, but being able to extend annotations of one page to the same page in a different name space could have some benefits.

A practical example is the Semantic History extension :http://www.mediawiki.org/wiki/Extension:SemanticHistory

Having these annotations in a separate namespace and still related to the original page would help.
