Improve the project element

[steingod]

We should consider to extend the project element. Today we have short and long name:

<project>
    <short_name/>
    <long_name/>
</project>

We should also consider to add information on the funding source for the project. E.g. something like:

<project>
    <short_name/>
    <long_name/>
    <funding_source/> # Controlled vocabulary preferably
    <grant_reference/>
</project>

Or something similar. These elements need to be optional as they will not exist for older data, but I think more will come onwards. Thoughts?

Maybe it's good to clarify what these new fields are. Would funding source be the funder, like "Norwegian Research Council", "European Commission" or the funding program like "Horizon Europe", so at which level would it be? Do we need to host a controlled vocabulary?

For the grant reference would that be just a number?

And we need a way to provide this in ACDD as well. For now we have :project = "long_name (short_name)";

[steingod]

The granularity differs between funders. I see PANGAEA has a flexible approach based on 3 elements, agency/institution, programme and grant number. The latter is best described as a string as it isn't always a number. Some agencies have a string that includes the programme.

Concerning controlled vocabulary we could have a list of commonly used, but there will be less commonly used sources as well so need some flexibility.

ACDD implementation would be good, but shouldn't be a show stopper.

Concerning ACDD, perhaps add a field for this specific purpose. Including in the project element would be too much overloading.
