What I’m trying to do
Can a vault owner enable other people to contribute notes in their vault without sharing the owner’s account credentials? I would like to invite a couple of fellow writers to help me build a knowledgebase.
There are no collaborative features for Obsidian Sync at the moment.
As for iCloud, you should be able to share the vault folder using iCloud’s built in options. See:
You may need to tap an option labelled something like “Share folder with iCloud Drive” before an “Add people” option appears.
However, for the record, this isn’t officially supported. Do some testing with your collaborators before you run wild with this. I’m not sure how well it would handle editing the same file at the same time, or simultaneous preference changes, for instance…
For official project documents you would definitely want revision source control, and you cannot use an unknown third party plugin.
Perhaps you can use git directly. Specify git to ignore the “.obsidian” directory. After a git refresh do a “refresh app without saving” from the command palette to read in contributions from other writers.
