The most comprehensive and integrated Free / Libre / Open Source enterprise software suite, WikiSuite is especially suited to knowledge-centric organizations and offers most (80%+) of the data and information management features all organizations need.
I’m a bit confused, but as far as I understand is Wikisuite a bunch of free and open-source software applications and you have the choice to use what you need (https://wikisuite.org/faq#Is_WikiSuite_just_a_list_of_software_). On one hand it also seems that these different software applications are especially for ClearOS, but on the other hand you find them individually here (since they’re all FOSS): https://wikisuite.org/Source-Code. So maybe I’m confusing something haha. Anyways, the website has a facebook tracker and links to some trade-based networks, but the official link to github links to the software and the software seem to be trade-free, that’s why I give 5/5.
