Martin, all,

please note that datatype properties that accept a string as their value
do no longer have xsd:string as their range. Use untyped literal
instead, which allows you to add a language tag to the values.

Martin, I checked your example, and have a few remarks:

* some properties have a dummy value (locationLongitude, description).
Since those properties do not appear in the original file, it is better
that they do not appear in the RDF either.

* it is not absolutely necessary to duplicate all inverse properties
(createdIn/isCreationLocationOf, features/playsIn, ...). However, it
does not hurt.

* the creation date of the resource is not a valid dateTime... I know
this is a pain, but OWL does not allow use to use underspecify dates...
We should do something about that.

Appart from that, very nice example... I attach the Turtle version,
generated by cwm, and much more human-readable...
