Hi, I'm trying to combine Xwiki products into an intranet collaboration solution and would appreciate advice on good practices for this. We're talking a manufacturing organisation, about 500 users, divided into a dozen production departments with users working on various departmental and organisation-wide projects. I was thinking one could have Xwiki Enterprise operating as the portal containing all the common enterprise info, then have Workspaces for departmental document use and Chronopolys for Project management. I'd love to have a single install product but that doesnt seem to be possible as I understand it. I also don't forsee any more wikis than the above 3 being required. Using the 'quick links' shortcut menu on XE I can add the URLs to the XWS and Chronopolys spaces and provided one saves login details its pretty seamless to transition between the products while working. At the moment I have the 3 Xwiki products running on separate virtual machine servers i.e. separate IP's, Tomcat6 or Jetty app server, Java6 and Postgresql databases. I'd like to know how much of this can be practically integrated. I realise I can most likely combine everything into a single VM, running a single app server with different URL paths and separate databases but ... more importantly how can I get more synergy with the 3 products working together? Q's like: 1. Could all 3 products run on the same Xwiki database in Postgres or would there be conflict with users, tables, etc. If not all 3 how about just XE and XWS on the same database? Is this possible or am I looking for problems? 2. I'm not sure where the user uploaded wiki attachments are stored, if in the db then ignore this Q, but if they are stored in the OS file system then is it possible to have a common uploaded file space for all 3 platforms? 3. Also, there seems to be some sort of integration possible with Alfresco CMS stored files - is this for XE or could XWS/Chronopolys also access Alfresco docs? Thanks
