Replication of published subject indicator as thesaurus by means of LDAP

Abstract

Published subject indicators (PSI) are public available descriptions of non-addressable subjects. PSI sets can be used as shared vocabulary. Different Topic Map authors can use the same PSI sets to assure that topics dealing with the same subjects are recognized as identical topics by arbitrary Topic Map engines. There is no standardized structure for PSIs or PSI sets. There is no concept for distributed and replicated PSI sets. Both are required features from several application classes. This paper describes how thesauri can be used as a schema for PSI sets and how existing thesauri can be converted to Topic Maps. It is also explained how LDAP can be used as replication platform for PSI sets. © Springer-Verlag Berlin Heidelberg 2006.
