Abstract
The DDC is constantly changing. In order to keep the classification up-todate with scientific advancement and literary warrant, the editorial process regularly revises specific areas in the tables or schedules and, as a result, particular topics in a class are relocated into other classes or new, subordinate classes are created. In the German National Library, the DDC is the most important system for classification and indexing. Strictly speaking it is necessary to regularly review the correctness of the DDC notations, since their new meaning may not correctly reflect the contents of the bibliographic medium any longer. However for economic reasons this is not possible with the result that a search for literature on a specific topic may return improper resources, as that topic might not be represented by the used DDC notation anymore. In a small research project, the German National Library is currently investigating if it is possible to solve this problem by giving each version of a DDC class a unique identifier. By doing this it would be possible to explicitly label which version - and thus which topics are contained - of a DDC class was used for the classification of a particular resource. If those identifiers conform to the generic URI syntax, we can model the relations between the bibliographic resources, the subject headings and the different versions of the DDC classes as a semantic network using RDF and then investigate if this approach can improve retrieval in heterogeneously indexed collections. This article presents some preliminary results.
