OSDD portal components. All the components of the portal are open-
source applications. At the core of the portal is the RDF data store which integrates
data from all the applications integrated into the portal. The portal has been developed
in collaboration with Infosys Technologies.
opment of projects to posting of the results on an open laboratory notebook
to facilitating comments on these. In addition, a number of researchers offer
their own informatics tools, with their own servers, for facilitating research.
The portal framework is designed to link these resources in a federated
manner. Components of the portal (Fig. 20.1) are discussed below.
20.3.1
Single Sign On
The OSDD portal is an integrated system using applications with their own
authentication mechanism which has been merged under a single sign-on
(SSO). The SSO is responsible for authentication of OSDD portal users and
establishment of SSO across all systems. This federated system ensures more
collaboration giving more freedom to the developer and also helps to integrate
newer applications easily.
20.3.2
OpenID Server
The OSDD portal hosts an openID server and helps the members establish
an open id account with OSDD and use it to log on to the portal. It is based
on the Lightweight Directory Access Protocol (LDAP), which is an application
