Windchill does a great job of comparing the attributes (meta data) and relationships (Uses, References) between different versions / iterations of Documents and Parts.
I am looking for ways to compare content files (Actual file content not just file names) associated with multiple versions of documents.
Use Case: There is an intent to revise Specification documents and update the content of the primary and attachment files. During the review process, users have to track the changes on the newer revision (to make it easier for approvers) for review and apply all of teh changes at a later time.
It will be easier if we can just present the differences between two versions of file attachments (Just like how Software source control differences compute the differences in text of the software files).
In this case, I will know what files are involved. I am looking for a server side (Windchill / Doc Worker /Apache POI API/ Microft technologies etc..) technology that can accept teh files and publish the differences report that looks similar to Office Trach Changes functionality.
