Make Thoth records DORA compliant

[vincentwj]

Issue description extracted from https://github.com/thoth-pub/thoth/wiki/DORA (at revision 7edb8e2). This has now been removed from the wiki page (under revision 7900d3f) as it is more appropriate to track as an issue here.

In particular point 8 seems relevant for Thoth, namely the clear acknowledgment of the authors of the metadata records produced in Thoth. Currently, ONIX records output in Thoth only list the "sender" in the header, with incorrect email address:

<ONIXMessage release="3.0">
<Header>
<Sender>
<SenderName>punctum books</SenderName>
<EmailAddress>javi@openbookpublishers.com</EmailAddress>
</Sender>
<SentDateTime>20210607T113458</SentDateTime>
</Header>
<Product>

Suggestion would be to link the sender data to the account that created the metadata record that is being output. Though multiple user accounts may work on the same metadata record, this would at least give a better approximation of authorship acknowledgment and potentially make Thoth records DORA compliant.

(Point 8 of DORA: Encourage responsible authorship practices and the provision of information about the specific contributions of each author.)

Discussed with @rupertgatti and @ja573. Our reading of DORA is that it is not concerned with authorship of metadata, only of content. We also could not identify any field in the ONIX specification which covers authorship of metadata. There are no person-specific fields in the ONIX "Header" other than the "Sender", which is only intended to designate the person who submitted the ONIX message (if applicable), not to imply anything about who authored the metadata contained in it. We therefore don't think the suggested change to the "Sender" field is required.

Other than this specific point, it is publishers' responsibility to ensure their records are DORA compliant, not Thoth's, although Thoth certainly can (and does, and/or will with the Traffic Light System) encourage them to provide as much detail about authorship as possible.

(Note that since the original issue description was written in June 2021, the "Sender" field has been updated as follows:)

<Sender>
<SenderName>Thoth</SenderName>
<EmailAddress>distribution@thoth.pub</EmailAddress>
</Sender>
