LDAP 2 SPARQL

Accessing RDF Knowledge Bases via LDAP Clients

In order to exploit the client support of LDAP directories with the semantic expressivity of RDF knowledge bases, we aim at integrating RDF knowledge bases into LDAP directory services.

LDAP 2 SPARQL is a Backend to the widely used OpenLDAP server. It translates LDAP queries into SPARQL queries, asks a SPARQL endpoint and translates the result back to LDIF.

Sorry, I don?t speak SPARQL ? A Survey
Many Semantic Web applications are currently based on SPARQL. In particular, an increasing number of systems, such as question answering systems, keyword search or search by example internally construct SPARQL queries. However, lay users do not understand this language, so it is difficult to give the user feedback on what queries the system constructed. To [...]

Introduction

LDAP based directory services are an important part in the IT infrastructure of most organisations and enterprises. They act as a central service for integrating new applications into an IT infrastructure and can be accessed by many different types of clients ranging from content management systems to personal email tools.


In order to exploit the client support of LDAP directories with the semantic expressivity of RDF knowledge bases, we aim at integrating RDF knowledge bases into LDAP directory services. The ultimate goal is to use standard LDAP clients such as e-mail and address book software as well as software relying on LDAP authentication with RDF knowledge bases as backends.
