Dear OpenMath 3 developers, in the course of the integration of OpenMath into my semantic wiki SWiM, I'm currently working on an ontology for content dictionaries (more details to be announced separately), and there I'm asking myself how to represent metadata for content dictionaries and parts thereof. First of all, I had a look at the metadata of CDs as specified in the OM 2 standard. Some of them are quite generic, so it makes sense to me to reuse vocabulary from well-known ontologies like Dublin Core. I found the following reasonable mappings:
CDName = dc:identifier Description = dc:description CDDate = dc:date CDComment = rdfs:comment Other properties like CDBase, which are not available in some common external ontology, I defined myself. But for those we can use e.g. from DC, wouldn't it make sense to use the DC terms in the OpenMath XML markup altogether, and to allow the full set of DC (see http://dublincore.org/documents/dcmi-terms/)? There are more interesting properties there, such as dateSubmitted, or license, which are not part of OM2. The result would then look like this (with proper namespace declarations): <CD> <dc:identifier>arith1</dc:identifier> <dc:description>Arithmetical operators</dc:description> <dc:dateSubmitted>1999-01-01</dc:dateSubmitted> ... </CD> And now that we are at it, what would you think about allowing these metadata for subsections of CDs as well? That is, for CDDefinition, Example, Signature, …? Best, Christoph -- Christoph Lange, Jacobs Univ.
