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.

LOD2 Plenary Meeting: WebID and Authorization SIG
Today morning, we started the main LOD2 plenary meeting in Vienna. The first half day session the WebID special interest group discussed about WebID based single sign for the LDO2 stack and authorization. The challenge here is to provide a interoperable authorization layer which describe user, groups / roles and access to different parts of the stack as well as the managed knowledge bases. We agreed on the following short and long-time goals and activities: WebID registration service and stack internal authorization policy.

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.
