[Keys] Use more transparent URIs and include some alignments when possible

[pasqLisena]

In the keys vocabulary, we have records in this format

<http://data.doremus.org/vocabulary/key/2> a skos:Concept ;
    skos:prefLabel "Do majeur"@fr ;
    skos:editorialNote "unimarc: c"@fr ;
    skos:prefLabel "C Major"@en-us , "C Major"@en-gb , "Do maggiore"@it , "Do mayor"@es , "C Dur"@de ;
    skos:inScheme <http://data.doremus.org/vocabulary/key> .

I propose to change the URI on the base of the UNIMARC code:

<http://data.doremus.org/vocabulary/key/c>

---

Moreover, I put also attention on the MusicOntology version of the keys vocabulary. I put an example in n3 for readability.

keys:CMajor a keys:Key ;
    keys:mode "major"^^xsd:string ;
    keys:tonic keys:C ;
    keys:wikipedia "http://en.wikipedia.org/wiki/C_major"^^xsd:anyURI .

Mode and tonic are useful information. It is foreseen an alignment to this vocabulary?

+1 for making the URIs more transparent and for adding alignments when necessary

Was the .ttl modified by hand or did you made some modifications to other resources as well (speadsheet? open refine project?)

Open Refine.

I saved the new project on Google Drive (modelisation/referetiels/mise en commun).
