Hi Jun, You are right. The code [1] also confirms this. There seems to be, at the moment, no API for adding a tag instead of replacing all of them. This is not very nice, or even safe, because you risk overriding someone else's changes since between the time you get all tags and post back the (older and) modified version to add/delete a tag, someone else might have already added/deleted a tag. Please feel free to fix the documentation [2] and, why not, also make a nice contribution to the REST module by adding the missing "/wikis/{wikiName}/spaces/{spaceName}/pages/{pageName}/tags/{tagName}") resource with 3 methods (PUT for add, DELETE for remove and GET just to display a single tag) in the PageTagResource class in the same package. You can just copy the code from [1], rename things accordingly and replace the method bodies with the logic to add/remove a tag. The resulting resource should look rather more like [3], but for tags instead of pages. All of this must be done in a fork of xwiki-platform and, at the end, a pull request must be issued to apply the changes into XWiki. Oh, and don't forget to create a jira issue to which you link the pull request. Also, as a general note, please feel free to benefit from XWiki's open development model and, whenever encountering missing REST API (for example), (specially if it's a minor thing) feel free to patch it up yourself. You can learn more about XWiki's data model, it's components and the REST API itself. Also, you can either wait forever for a missing feature to be added, or just go for it and add it yourself, ending up with the result you want instead of a half-baked one that is relying on other people that are busy with other things :) Of course, all of the above are just recommendations. Don't feel obligated or anything :) Thanks, Eduard ---------------- References: [1] https://github.com/xwiki/xwiki-platform/blob/master/xwiki-platform-core/xwik...

Dear all,

I am trying to add a tag/tags to a page. However, it seems to me that there is an inconsistency between XWiki REST API document and its implementation.

http://platform.xwiki.org/xwiki/bin/view/Features/XWikiRESTfulAPI#HTagresour... The document indicates that PUT method can take <tag> element and will add a tag.

However, the implementation only takes <tags> element (via xml/application) and PUT method replaces all the existing tags with the new tags included in the <tags> element.

Is there a REST call that only adds a tag to the page without replacing all the existing ones?

Best regards
