Quoting roles in data services

[Stéphane Erard]

Hello


I'm reviving an old request from the Solar System community but more general in scope:
What are the common practices concerning references to data services? How do we cite creators of content (ie: data) vs services (ie, very often: a metadata table)? Can there be 2 different roles? - this is a recurring request from our providers, and a sensitive one.
Example: I'm maintaining an EPN-TAP service identifying planetary data from the HST catalog. Creating the metadata table is a significant work which deserves identification and involves a responsibility; but I can't pretend I've created the data. How do I call my role there?

VESPA distinguishes 3 roles, following current practices: Creator, Contributor, Publisher
But there is an obvious ambiguity with Creator that needs to be addressed.

Cheers
Stéphane
