Migrated attachment parameter wrapped inside AttachmentResourceIdentifier

Dear community,

in some of our apps we must interpret migrated content. Now we have an issue with one of our customers where attachments inside <ac:parameter ac:name=“name”> are not shown as usual but wrapped in an AttachmentResourceIdentifier. However I could not find any documentation of this construct.

Thank you


The value inside the “name” parameter is obviously the toString output of the AttachmentResourceIdentifier class of Confluence Server/DC which might contain nested stringified classes of e.g. PageResourceIdentifier. We implemented a function to handle this but it still remains unclear under which conditions the storage format contains this and where this is properly documented.
