Using query for smw maintenance

[eva...@gmail.com]

Hi,

I installed the semantic bundle to implement an internal application.
To have an overview of our "data model" and maintain the integrity,
I'm writing some queries. Unfortunately the ask function parser has
some limitation. For example, it's not possible to list all properties
that are not in the category "Schema", here a pseudo code :
{{#ask: [[Category:!Schema]] [[Property:+]] }}

Or I can't write a query that list all Templates that are in the
category schema,
{{#ask:[[Template:+]] [[Category:Schema]] }}

I'm wondering if the sparql parser for smw as the same limitation?

Any idea or example?

Regards,
Olivier
