Issue: Giving each wiki article it's own editorial rights?

Not certain of this, but having a secondary group with the permissions you want, which an administrator could add them to would allow you to gain those rights, but to do it individually isn't.

It is, however, possible to setup collaberation protection on a wiki article. That is, they can set it so only approved usergroups and the creator can edit an article.

You cannot set editing permissions entirely on a per-article basis. What you can do is what Mokonzi suggested, add collaboration protection to the article. It will only allow the creator and moderators to edit the page.

Or you can set this up globally, so your users don't have to set collaboration protection - by removing "Can edit wiki articles?" permission and leaving only "Can edit own posts?" turned on for that forum. This will affect all pages in that forum at once - only the creator and moderators can edit the page.

But there is currently no way to add a per-page-user-whitelist. This would only make any sense on pages where the above conditions are true, and collaboration protection in its present state was added mainly for backwards-compatibility with NuWiki pages. You can feel free to post a feature request for that in the tracker.

That is not a good option for me, as I would need to set up 50 user groups.

Not sure how what I said even remotely implies you need more than 1 user group. It can all be done with one... Like I said, just remove the edit permissions mentioned, and then everyone in that ONE group will only be able to edit articles they created themselves.

Great idea !

Sounds great!

Because I have 50 articles, and I want EACH article to have different users controlling it.

Yes, in the scenario I described, EACH article would be controlled by its own creator. This would not require any more usergroups than you already have.

Unfortunately, that doesnt work...

All 50 articles were created by me... and I want to give TWO different people rights over each article.

Well should we ever add the feature of specifying dedicated editors for an article, that is the permission that would have to be used.

I think most sites would like the ability to assign specific people to be wiki entry editors.
For forums, isn't there such a thing as access masks where for a specific forum you can create specific permissions ?
Does that methodology apply to this situation ?

It does in theory, however, he is looking to give article creators control over access masks that only apply to 1 wiki page.

Default access masks as I understand them apply to an entire forum or sub-forum, and the masks can only be controlled by admins.

I am having a really hard time achieving this. I've turned off can edit wiki articles for a usergroup and now they are not presented with an edit wiki link anymore to articles that they have posted.

Marking this as "in progress" as the permissions system has been redesigned in version 4 with this in mind (it is technically possible to save and fetch access masks efficiently). We have yet to create any interface or integration of it with respect to access masks specifically, however, hence the "In Progress".

Updating this as I have thought of some improvements for the Permissions System in VaultWiki 4.

1. Allow us to fetch permissions for multiple users at once. This would mean redesigning part of the class so that permissions aren't calculated immediately after the query, but stored in memory.
2. Give users the option to continue using the datastore to hold the permissions. This would eliminate a query or two on some pages and would be not much different than if the wiki was still saved as forums.
3. Create a new section of options for the permissions system.
   
   • Allow per-user access masks
   • Allow per-node permissions (more specific than forums)
   • Allow user-defined permissions (what the OP is asking for)
4. Force database permissions if any of the above 3 options are turned on.
5. User-defined permissions are settable based on a new canpermit setting - Users can create access masks on a per-node basis if they created or moderate that node. They can only grant permissions lower or equal to their own.
6. The additional permission caneditown would be needed for user-defined permissions to be useful in any way.
7. There should be an option to set the default protection layer for articles in certain areas to make enabling user-defined systems more efficient.
