I think we should also consider the concept of letting end users request things to be bookmarked, or possibly have a "my bookmarks" end user section that is separate from the global bookmarks.
Here is how we might handle both:
End user logs in and browses to the bookmarks
Click Add Private Bookmark. This opens a form similar to the current bookmark form
Fill out the form normally and save
Test to confirm it works as expected
Edit the bookmark
Set a field to flag request promotion to a shared boookmark and save
Components:
Add new UserBookmark form with supporting views and agents.
Alternatively, this could be CustomBookmarks with an extra field/parameter. This complicates the role logic, but could simpilfy CustomerBookmarkRead
Include a RequestPromotion field to flag this for administrator view and promotion
Create a process for administrators to review and allow proposed bookmarks. For example
Email alerts when there are pending entries?
Views for Pending and History
An agent to quickly convert the approved UserBookmark documents to CustomerBookmark
A UI update. I would suggest mostly reusing the Custom Bookmark form, and only changing a couple labels. The roles would determine which version of the form is used.
