Exemplify semantic indexing with ILC2 (requires memberRoles+memberList)

[nichtich]

Semantic indexing can be expressed with a Concept Bundle using memberRoles. This can be exemplified with the faceted classification ILC version 2, which has been expressed in RDF. An example (from here):

Facets:

2  in location
3  affected by agent
6  having property

Classes using the facets:

mqvt2l		mammals, in bacteria
mqvt3l		mammals, affected by bacteria
mqvt6l		mammals, having bacteria

To keep order to distinguish mqvt3l and l3mqvt both memberList and memberRoles must be given in the same Concept Bundle:

{
  "notation": ["mqvt2l"],
  "memberList": [
    {"uri":"http://www.iskoi.org/ilc/2/class/mqvt"},
    {"uri":"http://www.iskoi.org/ilc/2/class/2"},
    {"uri":"http://www.iskoi.org/ilc/2/class/l"}
  ],
  "memberRoles": {
    "http://www.iskoi.org/ilc/2/class/2": [
      {"uri":"http://www.iskoi.org/ilc/2/class/l"}
    ]
}

The notation of a combined class can be derivde
