User right management

Post by Hajo » Tue May 15, 2018 11:07 am


we plan to use XN View MP in our company for picture management (especially marketing porposes). To ensure, only authorized persons can tag pictures as “approval for marketing”, we need some kind of user right management.

Is it possible to add a user right management to XN View MP?

What I have in mind:

Admin: Allowed to use the complete functionality, especially to add categories.
Super User: Allowed to tag pictures with all categories. Especially some “Master-categories”, i.e. “Approval for marketing”.
Users: Allowed to search with all filters (categories, quality and colour indication); allowed to tag pictures with all categories, except “Master-categories”
Viewer: See only pictures with "approval for marketing"

It should be easy, that the categories will get a flag “Master” or “normal”, which can be checked by the user management.

Best Regards

I assume all those pictures reside on some kind of network drive and would be accessed from multiple clients eventually at the same time? Probably this will rise additional questions regarding cached metadata, thumbnails and so on...

Did you think about using folder permissions as a second dimension to categories? You could have three folders on the network drive "super user", "user" and "public". You could grant read and/or write permission for each folder to different user groups since you probably already have a reliable and proven user management for network drives. You could have a background job to synchronize approved pictures to the public folder. Since you have so many people working on the same data I would even think about using only folders to flag workflow state and to use categories only for the type of the image.

It's just an idea :D

Yes, the pictures are stored on a network drive and we will have different users. The db-file will be stored at the network drive. The thumbnails should be stored locally at each Laptop/PC.
I think only an internal user right management will bring the safety. The second dimension via folder permissions cannot represent the functionality, I need.

The Szenario A:
3 folders: “new data”, “internal data”, “public data”
3 user groups: “super user”, “user”, “viewers”

Users and Super User are allowed to add files to this folder. The “Super User” has to decide if these pictures are “internal data” or “public data” and move it to the right folder. (read/write permissions for both folders)
If the “Users” have no write permissions to the “internal data” folder, it would be not possible to tag those pictures (Tags in metadata need write permissions). Pictures can’t be found/filtered without tags.
If the “Users” have write permissions to tag public pictures, they would also be able to move
internal pictures into this folder. Windows does not distinguish between “add file” or “alternate file” in it’s folder permissions.

The Szenario B:
3 folders: “super user”, “user”, “viewers”
3 user groups: “super user”, “user”, “viewers”

Super User is allowed to tag pictures in all folders.
Users are allowed to tag pictures in user folders and viewer folder. If public pictures are stored in “viewer folder“ and internal pictures are stored in “user folder”, we have again the problem, that it would be possible for users to move pictures from “user folder” to “viewer folder”.

The second KO-criterion is, that XNViewMP can’t forbid users to tag files in random other folders (i.e. project folders) with the tag “public”. These pictures would be found with a category-filter by XNView.
