I�m newbie in this, but may be I can help. We are developing with newsML.
It's an xml schema for media types. It's using by Reuters, AFP, Wall
Street Journal, etc. The newsML it's the standard for www.IPTC.org. So
you can have metadata and the images embebed or a reference, and any other type.
Wermus,
You may also look into Topic Maps [TM], as NewsML was designed to be a
compliant application of ISO 13250, the Topic Maps standard. Topic Maps
have more generic semantics than NewsML, doing generic mapping of resources
that NewsML does for the specific application of news publication. So if
one's application isn't news per se, Topic Maps are probably a better fit.

I'm running Xindice 1.1b4 in a tomcat 5.0.19 environment and I want to
search for stored documents by using the MetaData Information, Xindice
assigned to the documents.
It was no big problem to import and export both, XMLResources and
BinaryResources. Also the assignment of SystemMetaData (CreationDate,
ModificationDate) and CustomMetaData (based on Dublin Core) could be
realized. But how can I query the database (for example per XPath) and
search for specific documents using the MetaData-Information.
My first idea was to store the MetaData inside the XMLResources and query by
XPath, but this doesn't work with binary objects of course.
I didn't find any functions for querying MetaData in the DB:XML API.
Perhaps anyone can help me?
Unfortunately, such function is not implemented. If you can, you can
implement it and send patches to the dev list for incorporation into
xindice.
Thanks,
Vadim

The North American Aerospace Defense Command had gone so far
as to develop exercises to counter the threat [of flying jets

randum unearthed by the commission, planned a drill in April
2001 that would have simulated a terrorist crash into the Pentagon.
