naming labelled instances

Hi team,

At the teleconference last week we discussed that sometimes it is
advantageous to name common property values with URIs, then use labels to
give textual versions of those property values. I've added this to the
Artstor stylesheet, and I've been using Brownsauce to investigate the data
as Eric suggested. However does anyone have any recommendations on how to
name these URIs? At present I am using a schema namespace of

http://www.dspace.org/simile/schemas/artstor-06oct#

and various property value namespaces e.g.

http://www.dspace.org/simile/metadata/artstor/id#
http://www.dspace.org/simile/metadata/artstor/source#
http://www.dspace.org/simile/metadata/artstor/image_id#
http://www.dspace.org/simile/metadata/artstor/object_id#
http://www.dspace.org/simile/metadata/artstor/mediafile#
http://www.dspace.org/simile/metadata/artstor/resolution#
http://www.dspace.org/simile/metadata/artstor/mediafileformat#
http://www.dspace.org/simile/metadata/artstor/collection#
http://www.dspace.org/simile/metadata/artstor/creator#
http://www.dspace.org/simile/metadata/artstor/material#
http://www.dspace.org/simile/metadata/artstor/recordType#
http://www.dspace.org/simile/metadata/artstor/site#
http://www.dspace.org/simile/metadata/artstor/geographic#
http://www.dspace.org/simile/metadata/artstor/format#
http://www.dspace.org/simile/metadata/artstor/topic#

with the property value coming after the hash.

Now ignoring the question of the correct stem for the namespace, which we
also discussed at the telecon, I'm not sure if I have chosen my fragements
and namespaces correctly. Is it good practice to do it this way? Would it be
better to have the property value type after the hash and have a single
namespace? Alternatively is the schema we use for namespacing a irrelevance,
and as long as we don't have namespace collision is everything ok?

One "nice to have" would be to browse by topics e.g. list all the topics in
this dataset. However this would seem to require subclass relations, right?
Or is there another way of doing this?

kind regards
