  4. 4 The modifications can lead to incomplete search results | 18 | Concepts in Context | Versioning of the DDC | July 19, 2010

  5. 5 In spite of the modification thesearch result should be correct ? ? ? ? ? ! ? ddc= 726.79* | 18 | Concepts in Context | Versioning of the DDC | July 19, 2010

  6. 6 We create identifiers for each version of the DDC classes and a Semantic Network for searching Title Title dc:subject dc:subject dct:replaces DDC class identifier DDC class identifier dct:isReplacedBy skos:broadMatch [2007-01-01] {2010-06-16} dc:subject dc:subject skos:broader skos:narrower skos:closeMatch [2010-06-16] Subject Heading DDC class identifier Title dc:subject dc:subject Title Title | 18 | Concepts in Context | Versioning of the DDC | July 19, 2010

  7. 7 Each version of a DDC class getsa unique identifier 726.796 Cloisters Class here comprehensive works on cloisters [formerly 726.69] [2009-03-30] http://dewey/info/class/726.796/2009/03/30/ | 18 | Concepts in Context | Versioning of the DDC | July 19, 2010

  8. 8 Through the identifier we can differentiate between the versions 726.79 Parts and accessory structures Including cells, cloisters, refectories [2005-11-02] http://dewey/info/class/ 726.79/2005/11/02/ http://dewey/info/class/ 726.79/2009/03/30/ http://dewey/info/class/ 726.796/2009/03/30/ 726.79 Parts and accessory structures Including cells, refectories [2009-03-30] 726.796 Cloisters Class here comprehensive works on cloisters [formerly 726.69] [2009-03-30] | 18 | Concepts in Context | Versioning of the DDC | July 19, 2010

  9. 9 Because of the versioning we can identify the meaning of a DDC class http://dewey/info/class/ 726.79/2005/11/02/ http://dewey/info/class/ 726.79/2009/03/30/ http://dewey/info/class/ 726.796/2009/03/30/ Mittelalterliche Kreuzgänge in Europa [2008-02] Infirmarien – Kranken- und Sterbehäuser der Mönche [2010-02] Die singenden Steine von Moissac [2010-03] | 18 | Concepts in Context | Versioning of the DDC | July 19, 2010
