24 6.2 Exchanging a whole thesaurus
6.3 Updating a thesaurus
6.4 Exchanging thesaurus subsets
a) single records, i.e. all the data associated with a single concept or term. Such subsets are trivially simple and may be conveyed using the appropriate elements from the recommended format, without the validations required for a whole thesaurus;
b) updates (see 6.3);
c) responses in the course of live indexing/searching applications (see Clause 8);
d) selections of data large and coherent enough to serve as an independent thesaurus.
