Hi Lars! Be careful with this general simplified notion.
In some areas of research author ordering can cause sort of religious wars. And I may also add that depending on the area of research, the question "I want all my papers, but only those where I am the first author" is /very/ common. Up to the notion "my papers" == only those where I am the first author == only those count at all. So, a destinction of 1xx/7xx (of course Ferran is right about the other fields) is really important as is the ordering field $b. -- Kind regards, Alexander Wagner Subject Specialist Central Library 52425 Juelich mail : a.wag...@fz-juelich.de phone: +49 2461 61-1586 Fax : +49 2461 61-6103 www.fz-juelich.de/zb/DE/zb-fi ----- Reply message ----- From: "Lars Holm Nielsen" <lars.holm.niel...@cern.ch> Date: Thu, Mar 27, 2014 17:08 Subject: [pu jsonalchemy] Aggregation of several fields into now To: "Esteban Gabancho" <esteban.jose.garcia.gaban...@cern.ch> Cc: "project-invenio-devel (Invenio developers mailing-list)" <project-invenio-devel@cern.ch> On 27.03.2014 15:38, Esteban Gabancho wrote: > Hey guys! > > I have a question about the aggregation of several fields into one. > > Taking the example of the authors, lets say I have two fields `_first_author` > and `_additional_authors` and I want to aggregate then into `authors`. > The common case, and the easiest, is when I have one `_first_author` and cero > or more `_additional_authors`, in which case I just put a list with the > authors (what else right? :-) > The problem, or the question, comes when I don’t have a `_first_author` in > which case I’m not sure about the content of the `authors` field, it could be > i) only the list of `_additional_authors` or ii) `None` follow by the the > list of `_additional_authors`. > > I think the second solution is the closest one to reality, the `None` express > that the record doesn’t have a first author.

In Zenodo i'm just interested in the list of authors, and the first in the list is by definition the first author. The first author/additional authors are somehow an artifact of having to store in MARC as master format. I'm not sure what we would be the most appropriate solution.
