Hi team,
As you probably know one potential confusion when using URIs to represent
objects is that convention to distinguish between the following situations
are not clearly defined:
- URIs that correspond to retrievable resources,
- URIs that are surrogates for real world objects,
- URIs used to identify digital objects and
- URIs used to identify metadata objects.
It seems sensible to use the URL as a URI for retrievable resources and
we've already had a bit of discussion about using MD5 hashes for identifying
digital objects. However I am not clear on the best approach to use for
surrogates or metadata objects. For example when we transform the Artstor
data to RDF/XML from XML, we use URIs that look like URLs for both these
situations e.g.
First identifying a metadata object:
<http://web.mit.edu/simile/metadata/artstor/mediafile#3-41822000125995.jpg>
a art:MediaFile ;
Second a surrogate for a real world object:
<http://web.mit.edu/simile/metadata/artstor/creator#Henderson,_T._Hunter>
a vra:Entity , person:Person ;
Does anybody have any suggestions about a better way to do this?
