[Xesam] Validator

[Antoni Mylka]

Xesamies,

After the discussion with Ivan, I've uploaded a little specification of
the validator we used in Nepomuk:

https://sourceforge.net/apps/trac/oscaf/wiki/Validator

Now I updated the validator code and wrote an ant task that encapsulates
it. Basically what you need to do is put a following bit of xml inside
build.xml:

<onttest>
	<ontologies dir="${oscaf.trunk.folder}">
		<exclude name="**/README"/>
		<exclude name="**/doc/**"/>
		<exclude name="**/pimo/**"/>
		<exclude name="**/tmo/**"/>
		<exclude name="**/base/**"/>
	</ontologies>
	<baseontologies dir="${oscaf.trunk.folder}">
		<include name="**/base/*"/>
		<exclude name="**/README"/>
	</baseontologies>
	<testcases dir="tests" />
</onttest>

The ontologies, base ontologies and test cases are specified as ant
FileSets: http://ant.apache.org/manual/CoreTypes/fileset.html It allows
for pretty fancy file choosing schemes.

I've uploaded a tarball with the sources of the ant task, all
dependencies and a build.xml script that compiles the java source,
validates all NIE ontologies and a single example file. It's here:

http://www.dfki.uni-kl.de/~mylka/nie-ant.tar.bz2

Please
- download, untar
- edit the build.xml to point it at the oscaf ontologies trunk folder
- type 'ant'
- and see the validation report (or some other problem in which case
send me an email).

Right now it detects 519 problems in NIE. All of them are due to missing
base ontologies:
- W3C Geo
- Masahide Kanzaki EXIF
- a little hack that states that all XSD datatypes are rdf datatypes

The missing base ontologies are included in the tarball.

I would like to create a tools/java folder in SVN and upload the
build.xml, the jars and the testcases there. I wouldn't change anything
in the 'ontologies' folder. If anyone is allergic to java he/she won't
have to check it out at all.

More testcases will come in near future. Stay tuned.

Any objections?
