Re: [xwiki-devs] Copy page through Restful API

Hi Eduard (and other RESTful API interested users), I am writing to this thread as I never heard back from anyone within the community on a recent posting I made on 2011/7/6 title working with REST API for integrating Sakai and XWiki. There I outlined the performance issues we were experiencing in our integration of Sakai with XWiki. I included some thoughts on a possible extension to the REST API that might help address some of the performance issues. I was looking for some feedback on it. The thought was to : given a permission setting and a list of users we would get back a list of pages or given a permission setting and a list of pages we would get back a list of users. It is my understanding that the RESTful API as implemented is not as mature as the RPC API, and that the REST API was becoming the preferred API. I would appreciate, as I know others in the Sakai community as well, to see if we can overcome some of the performance concerns related to XWiki's RESTful API. If the extension to the REST API as proposed makes sense or an alternative approach is there how is it best to move this forward?

Translated to application operations, you have Create, Retrieve, Update and Delete (CRUD). These are basic operations that can be composed to create more "complex" ones like copy (retrieve+create), rename(retrieve+create+delete), etc. While this is powerful enough to create any operation you would like, it's also a bit limiting for an application's scope because these "new" operations have to be implemented each time by the client, instead of having them available from the application trough an API. One simple example of problem generated by this fact is that the client will perform 3 operations for a rename (retrieve page + create page in new location + delete old page location) and this will trigger 3 application events in the application's (xwiki's) notification system instead of just 1. Modules listening for page copy or page rename events will not be notified because they were listening to 1 specific event, but 3 general events were used instead. The other obvious concern is the performance of 2/3 operations (each sending and receiving data over the network) versus just 1 (possibly optimised). A "not-so-hackish" solution could be used on the application side to provide an extension to the basic HTTP operations by using parameters such as... ".../spaces/Main/pages/Test?action=copy&destination=Tests.Test", just like we do to overcome browser limitations for the HTTP method [1]. Actually, we could just extend the possible values for the "method" parameter used in [1] by adding "copy" and "rename". ------------------ References: [1] http://platform.xwiki.org/xwiki/bin/view/Features/XWikiRESTfulAPI#HOvercomi… On Tue, Jul 12, 2011 at 5:23 PM, xManish <shresthamanish(a)gmail.com> wrote: copied that http://xwiki.475771.n2.nabble.com/Copy-page-through-Restful-API-tp6575262p6… _______________________________________________ devs mailing list devs(a)xwiki.org http://lists.xwiki.org/mailman/listinfo/devs
