There are various ways of attaching notes/comments to a node within AiiDA. In the first examples of scripting, you should already have notices the possibility of storing a label or a description to any AiiDA Node. However, these properties are defined at the creation of the Node, and it is not possible to modify them after the Node has been stored.

The Node comment provides a simple way to have a more dynamic management of comments, in which any user can write a comment on the Node, or modify it or delete it.

The verdi comment provides a set of methods that are used to manipulate the comments:

  • add: add a new comment to a Node.
  • update: modify a comment.
  • show: show the existing comments attached to the Node.
  • remove: remove a comment.
