[gilles landais]

Dear DataCP followers,

The version 1.1 of DataOrigin is available.
It improves traceability for VO users, help them to understand result sets
and facilitate data reuse and citation.

Data Origin is a light Provenance, made up of a lists of terms , easily
added in VOTable. In this new version, some terms have been modified
to have something more compatible with VOResource (registry).
The text and the plan have been revised too.

Thank for all contributors and implementers !
