Metadata Management
Provides a way for the user to edit User metadata directly in Tracker
Tags may be added/removed on the dataset Details page using a similar style as in CDAP UI
User Properties Metadata may be added/removed on the Dataset details page
If a user attempts to add a tag that is already on the dataset, a warning is displayed and the tag is not added.
If a user attempts to add a tag that is invalid (space, invalid char, etc), a warning is displayed and the tag is not added.
When a user tries to add a tag to a dataset, as they type, a list of tags is displayed along with a count of the number of datasets using that tag
Type ahead tags are displayed sorted by usage, the most usage is at the top.
All tags have “x” in them so they can be deleted.
Promoted Tags™
A way to indicate to your users the preferred tags to add to datasets.
Configured via the Tags menu bar
When the user first visits the configuration page, a list of all user entered tags is displayed sorted by alphabetical
User tags displayed in a table with the following columns
Column 1: Tag Name
Column 2: Count of datasets using this tag and clickable link to view all datasets which takes them to the Tracker search results page
Column 3: Actions
Promote
Promoted tags are displayed in a separate table above the user tags with the following columns
Column 1: Tag Name
Column 2: Count of datasets using this tag and clickable link to view all datasets which takes them to the Tracker search results page
Column 3: Actions
Demote
Columns are sortable
Promoted tags are visually different from User tags (green color)
Promoted tags can be added one at a time similar to how tags are added in CDAP today
Promoted tags can be added as a list or uploaded as a text file
When a user tried to add a tag to a dataset, as they type, a list of tags is displayed along with a count of the number of datasets using that tag. Preferred tags are displayed first and in a different color.
All tags are sorted by usage when user is typing (most used first).
When someone uploads a list that also contains user tags, those user tags are promoted to promoted tags.
Before preferred tags are uploaded, a confirmation dialog is displayed to the user indicating the number of tags that will be added. If some tags failed to be added, this number will be less than the number of lines in the file.
