We have out of the box adapters for several applications including ASAM, ClearCase, ClearQuest, DanTe, DOORS, EnterpriseArchitect, HPQC, Jira, Perforce, RIF, Rational System Architect, and Subversion.
You would need the IIP software itself, an IIP software license, and a separate database to be created for it (Oracle or Microsoft SQL Server).
For development, it is suggested to use Netbeans with the IIP SDK that is also offered on our PTC Software Downloads area. You would use the Netbeans NBM files to import the information for development you would want to use.
There is information that describes how to set this environment up. You can make your own adapter using the SDK if you wish. You would also need to have knowledge of BPEL to create sequences that use the adapters.
