So when you add an user to a group you add a new XWiki.XWikiGroups object to the group's document and set the 'member' property to the user name (XWiki.Ricardo) and the 'role' property to the role the user will have in that group (e.g. 'coordinator'). This sounds good to me. Hope this helps, Marius

Hi! <Ricardo.Julio.Rodriguez.Fernandez(a)sergas.es> wrote: Yeap, this sounds easy and good. But IMO there is still one thing I'm not confortable with in this approach. We use, or intend to use, XWiki group concept for different "real life objects". Let me give you three examples: 1. research groups (this is classical approach with a one person-one group belonging relationship) 2. research projects (the group will represent the research team); closer to research groups, but it has its own oddities and 3. scientific papers (the group will represent the paper's authorship); in this case, author order will be king. If we add a single new property to XWiki.XWikiGroups class, 'role' property, it will have different meanings and values depending of what "kind" of group it will represent. Won't be more advisable to create as many new properties as different meanings XWiki.XWikiGroups object instances will have? In this case, only one property will have a given value. The others will remain empty. This last fact together with the another issue: we are still using a 2.4 XE release, thus we are facing an update in the short time, make me very reluctant to extend any XWiki class. But, of course, if this is the best or the only solution, will go for it! We are thinking about a "third party" brand new class characterizing any group membership relation. But we have not conceptual model for this data system yet, so I can't offer an objective and independent representation about we are thinking about. Thank you so much for your help! Any idea, comment or criticism will be extremely welcome!
