What kind of integration are you looking for? EPDM (new name of PDMWE) has the posibilities to integrate with other systems, but the solution really depends on what kind of information you want to integrate and in which way(s) (EPDM --> another system or another system --> EPDM or both).
As far as I know, EPDM can export data in XML format and it is MS SQL database-based, that can be a start for an integration solution.
Thank you for the reply. Let me see if I can better explain what we are looking for. Many on-line collaboration and project management services offer the ability to share files from a central location with check-in and check out priveleges as well as revision tracking just like PDMWE. We would like to use one of these on-line project management tools to take advantage of their superior collaborative capabilities such as task assignments, whiteboard, on-line discussions which can be easily accessed by our clients while using PDMWE as the file sharing engine. The problem with using both a PDM and an on-line collaboration services is that files will have to be stored in different locations (ie. on the PDM and accessed through our web server) or the files will have to be duplicated on both the web server and on-line collaboration tool which defeats the purpose of having a PDM system.
