### Check list for new storage integrations

We intendEnd of the deletion to Begin of the deletion createEnd of the deletion a Begin of the insertion**SharePoint/OneDrive**End of the insertion Begin of the deletion check list for new storage integrations. This list should be usable to investigate anyEnd of the deletion file storage Begin of the insertionfrom within a work package.End of the insertion Begin of the deletion and the feasibility of extending the OpenProject "File Storages" module to integrate it. Only basic functionality is part of the check list, as the current state of the Nextcloud integration includes use cases, that are very specific. The check list will contain detailed requirements regarding the following use cases.

* Authentication (one direction, OpenProject needs to authenticate against the file storage)End of the deletion
* Begin of the insertionA **Sharepoint/OneDrive**End of the insertion Begin of the deletion File structure discoverability
* ReadingEnd of the deletion file Begin of the insertionstorage representsEnd of the insertion Begin of the deletion metadata

### WhatEnd of the deletion is Begin of the insertionscopedEnd of the insertion Begin of the deletion not included?

* this Epic no longer contains the management of the sharepoint "document workflow"
* the focus is on making sharepoint and onedrive available as file storages as they are, without the nextcloud specific use cases.
* no project folders

### Update 2023-09-18

* discussion about the impact of the upcoming integration on currently available integrations (namely Nextcloud)
* Decision was taken with the following points:
* the storage domain object inside OpenProject should stay as it is
* usage of storage objects (same for file links, project storages, etc.) should be the same regardless of provider type
