Dear Felix, > everything we have done so far, including the mapping table, the toy > implementations of the API and the formalization example in SKOS etc., > are one way mapping, mostly using properties available in XMP as the > target of the mapping. That is, property A-1 from format A can be mapped > to property XMP-x. So far I have not seen anybody in the Working Group > asking for a two way mapping, so I regard this as an unspoken consensus > that we are working "only" on the one way mapping. This is *not* exactly true. In the case of the toy example of a possible mapping formalization in SKOS, we have a two-ways mapping, since for example, the skos:related property is owl:symmetric [1]. The skos:mappingRelation might be reflexive, symmetric too.
