How to integrate ONLYOFFICE and Seafile within UCS

ONLYOFFICE Document Server is an open-source office suite distributed under GNU AGPL v3.0. It comprises web-based viewers and collaborative editors for documents, spreadsheets, and presentations. Document Server can be integrated with various cloud sync&share services, can be incorporated into the solution you're developing yourself, or can be used as a part of the complete ONLYOFFICE Community Edition.

Seafile is an open-source file collaboration and sharing platform that allows storing and managing documents.

Univention Corporate Server (UCS) is an open-source server operating system that unifies multiple services, apps, virtualized IT environments, etc. under a single interface allowing their central and cross-platform administration.

With ONLYOFFICE online editors connected to the Seafile Professional instance within UCS, users are able to create, edit and collaborate on documents in real time. docx, pptx and xlsx files are supported for editing and co-authoring. doc, ppt, xls, odt, fodt, odp, fodp, ods, fods formats are supported for opening and viewing.
