How to support the XML backup for spaces in Confluence Data Center?

Our plugin has data in ActiveObjects. Customers complain that the data isn’t included when they export a space in XML and reimport it on another instance.

Can anyone give me any pointer to documentation about integrating our plugin with the space export in XML format?

In addition:

  • Assuming we can embed our data in the export, how do we map the new IDs of pages?
  • How can we map the applink ID?

Thank you!
