facet value mapping

[dietuyt]

Many slightly differing values for certain facets could be easily mapped onto each other. Some examples (for Resource Type):

• image > Image
• WrittenCorpus > Written Corpus
• Application / Tool > Software

Not all of these mappings can be done by means of a data category, because quite some of the files are coming from OLAC. It would be extremely helpful if it were possible to define a mapping (per facet) of similar values, in a way similar to the national project mappings (with an XML file), in a format like:

<mapping facet="ResourceType">
  <from>image<from> <to>Image</to>
  <from>WrittenCorpus<from> <to>Written Corpus</to>
  <from>Application / Tool<from> <to>Software</to>
</mapping>

Of course this is no alternative to metadata curation but because a mapping like this could quickly resolve quite some issues and because curation is not always realistic this feature could lead to a significant improvement of the VLO's usability.

#410 (Merge facet values differing only by capitalisation)
#425 (Get rid of CamelCase and underscores)

These two don't exhaust this ticket completely, because we don't have a relcat equivalent on the level of vocabularies.
