[xwiki-devs] Switching from semantic media wiki to xwiki

Xwiki developers, Our company develops wikis. We set up the core wiki, and then write extensions to add specific tools depending on the subject of the wiki . All of our wikis have been developed with the MediaWiki platform, which is written in PHP and prefers the mySQL database. We need to convert over to a Java and Oracle solution; XWiki is a contender for us. To help us decide on xWiki, Do you mind answering a few questions for us such as the following? 1. One advantage of wikis for us is the revision history, fast creation of content, media uploads, and the user management. Are these things solved well with xwiki? 2. We need to add some custom tables to the wiki database and then save to those tables from a page form. Is that possible? 3. We need to develop forms for particular categories. The fields within the forms will be saved to your tables and our custom tables. Is this possible? 4. It looks like xWiki has components. We are just starting to experiment with your components. Are they helpful with your product? 5. Do you have hooks in the code or other possibilities to extend code without changing it? 6. Is it possible to change core code? User mark up differences between your xWiki and mediaWiki is not a big factor for us. Thanks, Mary
