The Annotations service allows the users to make comments and notify errors on the data available through CDS services.

You can see how to post your first annotation by going to the Quick start page.

If you want to know what has been recently annotated, there is a page to see the latest annotations.

Note: for the moment only Simbad objects can be annotated.

The Annotations service has been developed by Brice Gassmann, headed by Thomas Boch and Sébastien Derrière.
