The Provenance Data Model \citep{2020ivoa.spec.0411S} is based on Entities, Agents and Activities as defined in the W3C Provenance model. The model's main focus is the detailed documentation of workflows.

Dataset Origin (see \ref{sec:dataset-origin}) can be serialized with Entitiesand Agent. The query information including information such as URL and parameters (see \ref{sec:query-information}) can be set with the configuration extension of the Provenance DM of the Virtual Observatory \citep{2020ivoa.spec.0411S}.

For the serialisation of ProvDM instances within VOTables, MIVOT \citep{2023ivoa.spec.0620M} is available. At this point, however, the relatively complex model and many free parameters are obstacles for a wide and direct adoption of ProvDM+MIVOT to represent Data Origin, in particular when compared to the very straightforward mechanisms proposed here.

%``Last-Step-Provenance'' is a Provenance extension currently under discussion which would define a list of metadata corresponding to Data Origin. Its output will not be recursive and could be easily serialized in a table.\todo{If we write this here, everyone will ask: Well, so why don't we wait for that? Perhaps we ought to just drop this?}
