Can I share XDD files?

For instance, when multiple users are working in the same workspace, having the extract dictionary (SYMBOL.XDD) locked by one user slows down other users who need to add or make changes to the file. Is there a way for users to share that file?

The XDD file is like any other library resource file, only one user can have it at a time. Depending on what you are trying to accomplish, you could, however, create additional extract dictionary files, such as SYMBOL1.XDD, SYMBOL2.XDD, and so on. This lets you could add resources in each file, then import those resources into the original SYMBOL.XDD file. You could also set up an XDD file for each line of business you have.

If you do not use multiple XDD files, it is a good idea to check in the XDD file when you are not actually using it and only check it out when you need to add something. This will minimize any conflicts.
