Rational Engineering Lifecycle Manager can be used to view data from other applications using the Open Services for Lifecycle Collaboration (OSLC) specification. More information on OSLC integrations can be found here: Open Services for Lifecycle Collaboration integrations.
Detailed instructions on how to complete these steps for the products in the Rational solution for systems and software engineering are available here: Configuring OSLC consumers
Rational solution for systems and software engineering must be configured to integrate with the Jazz Reporting Service as described in: Configuring Rational Engineering Lifecycle Manager as an OSLC consumer of the Jazz Reporting Service
Once you have configured your Rational solution for systems and software engineering applications, there are additional steps required for Rational Engineering Lifecycle Manager to display preview information for other applications and to allow users to create links from artifacts in one project area to another.
This configuration is described in: Establishing cross-server communication to enable Rational Engineering Lifecycle Manager OSLC preview
Once Rational Engineering Lifecycle Manager is configured, you must set up access permissions for LQE, and configure each data source as a TRS provider for LQE.
This is described in detail in: Indexing your data with the Lifecycle Query Engine.
