Dear all, I agree with Nick. This approach realises the statement that CRM is not about (Entity and Proprty) names but about (common, language independent) concepts.
It also helps to manage multilingual version of the CRM when we have EXX in scope notes and can extend it with "full name" in a certain language. Example: <rdfs:Class rdf:ID="E21_"> <rdfs:label xml:lang="en">Person</rdfs:label> <rdfs:comment xml:lang="en">[Engish text]... E21_ [Engish text].......</rdfs:comment>. ... <rdfs:label xml:lang="ru">Личность</rdfs:label> <rdfs:comment xml:lang="ru">[Russian text]... E21_ [Russian text]...</rdfs:comment>. ---------------- But natural language descriptions with codes and names are simplier than descriptions with codes only! Dear Martin, I'am afraid that "stars" (or any other symbol) in xml atributes may lead to some problems: 1. <rdfs:label xml:lang="*en*"> Some systems do not recognize *en* as English (en). 2. <rdfs:subClassOf rdf:resource="*#E21*" /> and <rdfs:Class rdf:ID="*E21*"> refer to different entities . Maybe, we should write <rdfs:subClassOf rdf:resource="#*E21*" /> ?
