On Processing XML in LDAP
Pedro José Marrón , Georg Lausen
Abstract:
The proliferation of XML and its settlement as the de facto standard for information interchange in Internet, as well as the development of query languages like XPath, have lead to a paradigm transition in the Internet database world in favor of techniques based on semistructured data models. At the same time, there has been an increase in the deployment of implementations of the LDAP protocol to store the most varied information. Its data model characteristics lie closer to the semistructured model than to the relational or object model used in traditional database systems, while also offering additional benefits for the distribution, parallelization and off-site processing of queries. In this paper, we present the internal data representation and query model of an LDAP-based system used for the storage of XML documents and processing of XPath queries. The feasibility of our approach, as well as its practical relevance is backed up by experimental data.
