In Dublin Core, this information is carried in the dc:type element, which
indicates the "the nature or genre of the content of the resource".
Often, values of this element are taken from the DCMIType vocabulary,
which includes
Collection
Dataset
Event
Image
Interactive Resource
Service
Software
Sound
Text
Physical Object
Still Image
Moving Image
In LOM, this information can go into
5.2 learningResourceType
In RLLOMAP, for example, there is no problem with having
educational.learningResourceType = Sound
technical.format = video/quicktime
