Middleware: Advanced Directory Services and Applications

Time 10/16/03 08:45AM-10:00AM

Session Abstract

As part of the NMI (NSF Middleware Initiative), NMI Integration Testbed sites have been evaluating and implementing enterprise middleware. Sites have leveraged this opportunity to advance their enterprise directory structure and to build new directory-enabled applications. Topics include:

--NMI Components Take on New Meaning. As use of the enterprise directory increases and diversifies, institutions are finding some NMI directory components even more valuable than before. "Practices in Groups," "Metadirectory Practices for Enterprise Directories in Higher Education," and the new "Enterprise Directory Implementation Roadmap" take on new meaning as the long term and "inter-realm" vision for the campus directory is realized.

--Enabling Applications to Use Enterprise Authentication. Work has been underway at UAB to develop a central, authoritative database and directory. The UAB LDAP schema overlaps strongly with the eduPerson and InetOrgPerson schemae and, along with the LDAP Recipe, are core components used in designing UAB's LDAP directory schema. As an NMI participant, UAB has successfully enabled applications such as Instant Messaging (jabber), download of university-licensed software, Oracle HR system login, Solaris/Linux logins, and some simple content-management systems like Bugzilla and PHP-website. UAB will explain their general approach and also some specific steps taken for applications.

--Promoting Semantic Interoperability of Metadata for Directories of the Future. A challenge in LDAP schema design and interoperability is better understanding of schema inter-relationships across organizations. Georgia State has received NSF funding to research an approach based on the proposition that monitoring, clustering, and visualization of cross-organizational metadata can help identify patterns of practice and lead to dynamic evolution of standards. A semantic facilitator tool is demonstrated that uses Self-Organizing Maps for clustering and viewing metadata, and implements a Stereoscopic Field Analyzer (SFA) to visualize directory objects in 3-dimensional, interactive space.
