Hello community, I am looking for a self-hosted online document management solution. One that covers all my needs is Confluence but it is currently not affordable for my team. Key requirements are RTL support, WYSIWYG Editing (Word-like interface as much as possible), Concurrent Editing (the best experience I have with Google Docs where I can even see who else is currently editing a document) with conflict resolution, versioning (view history and switch between versions), PDF and Word export, complex tables, and some others, full list here in column "A". I found XWIKI covering all my requirements (including those "bonus features" that I didn't list here) except one - RTL. Here a hack is suggested to address this issues but I would prefer not to go with any hacks. I myself am ready to contribute to an open source development but other people who (hopefully) will use this tool are not software engineers and this fact must be kept in mind... Any suggestions are greatly appreciated!
