6 <!-- This schema represents a formalisation of a subset of the semantic conditions

7 described in the SKOS Reference document dated 18 August 2009, accessible
|
|
|
8 at http://www.w3.org/TR/2009/REC-skos-reference-20090818/. XML comments of the form Sn are used to
|
|
|
9 indicate the semantic conditions that are being expressed. Comments of the form
|
|
|
10 [Sn] refer to assertions that are, strictly speaking, redundant as they follow
|
|
|
11 from the RDF(S) or OWL semantics.
|
|
|
12
|
|
|
13 A number of semantic conditions are *not* expressed formally in this schema. These are:

A distinct vocabulary is provided for concept mapping relations, to provide a convenient way to differentiate links within a concept scheme from links between concept schemes. However, this pattern of usage is not a formal requirement of the SKOS data model, and relies on informal definitions of best practice.</rdfs:comment>
