Data origin is required for end users to understand data, for citation and for reusability. 

<span style="background-color: transparent;">We propose to list meta-data required to provide sufficient traceability to end-users in order to improve the understanding of the resultsets and enabling its reuse and its.</span>

For instance, a table published in a journal or by a Space Agency is also hosted in a Data Center like CDS, GAVO, etc. The data curation depends of the Data Center which can add associated data, enrich meta-data (eg: add filter for magnitude) or make a sub-selection of Columns.</span></span>
