Comments are free-form text notes which may be queried for, reported on, reviewed and managed by model. A comment tracks its author, creation time, update time, importance and status.
You can attach any file including pictures and multimedia to the model and refer to them in a comment. You can leave one or more comment(s) per object and see comments made by others.
Depending on your security role, you can edit and remove all comments, including ones written by someone else.
Unlike labels, comments only apply to the specific version of the model they were entered in.
In addition, these comments may then be exported out of Talend Metadata Manager and opened in External Metadata tool, there to be reviewed and edited in the original External Metadata model format (where supported in the External Metadata tool user interface).
