Zthes profile for SRU: changes between versions 0.5 and 1.0

2nd May 2006

There are no substantive differences between the prose of versions 0.5 and 1.0 of the Zthes SRU Profile. However, because the former uses version 0.5 of the Zthes XML DTD and version 1.0 of the Zthes CQL context set, whereas the latter uses version 1.0 of the Zthes XML schema and version 1.0.1 of the Zthes CQL context set, there are some important functional differences:

  • The new elements <postings>, <termUpdate>, <termVocabulary>, <termCategory>, <termStatus>, <termApproval> and <termSortkey> are added in version 1.0 of the XML schema.
  • The <termNote> element is now repeatable, and may carry a disambiguating label attribute and a vocab attribute prescribing a controlled vocabulary.
  • The <relation> element may now carry an optional weight attribute.
  • A whole-thesaurus descriptive record is specified.
  • The new indexes vocab, cat, status, approval and sortkey are added in version 1.0.1 of the context set.
  • ZeeRex Specifications are added for a content database to indicate a Zthes database to be used as an authority for one of its fields.
