i have this structure:

Groups -> Fields -> Values

and a command gV().hasLabel('groups').out('fields').out('values')

how can I group these values by fields and by 'groups' vertices?

Thank you

This was answered on the Gremlin Users list by Daniel Kuppitz :

 gV().hasLabel("groups"). group(). by(). by(out("fields"). group(). by(). by(out("values").fold()))
