Dear all,

Veronique and myself have our first toy example ready to demonstrate how 
the mapping of properties could work using semantics. The example maps 
properties from Dublin Core [2]  to XMP [4].

We see 4 different solutions on how we could approach this mapping:

(1) The first option is to use SKOS mappings [1]. The problem with this 
option is, that SKOS mappings were being conceived to hold between SKOS 
concepts and not properties. So we would  use the mapping vocabulary in 
a semantically incorrect way (from the point of the SKOS specification 
and the inference engines trying to make sense of it).

(2) The second option is to use owl:equivalentProperty / owl:sameAs 
which we can not consider given the different semantics of the 
properties defined in the different formats

(3) The third option is to subProperty all the properties from the 
formats to e.g. Dublin Core [2], Dublin Core Terms [3] or any other 
format which is generic enough.

(4) The fourth option is to create our own authoritative schema which 
consolidates all the formats we are looking at and to which the other 
formats can be mapped to.

Veronique has prepared a small example using the first option which 
matches from the DC properties from [2] to XMP properties from [4]. 
Please find the example attached (XMPtoDCskosMapping.rdf). The XMP 
properties came from the XMP example document which is also attached 
(xmpexample.xml).

We are curious to hear your opinion on the options above and our toy 
example.

Best regards,

Tobias & Veronique
