Funding in project are unnecessary wrapped in the Funded Element

[abollini]

As discussed in today 2020.11.19 cerif TG meeting the Funded element seems to be redundant. More specifically the By sub-element is overlapping with the purpose of the Funder element in the Funding, moreover the Funder in the Funding has a 0..many multiplicity where the By element accept 1 children at most.

The Funded structure should be deprecated in favor of a simpler Fundings element where 0..many Funding can be described or referenced. It is perfectly ok to include in the Fundings just a single Funding with no other information than the Funder if this is the only evidence know by the CRIS system (or the only information that it want to share).

In the meeting we have also discussed the opportunity to keep in place a wrapping element around the funding so to allow for instance in future to give more details about why the funding is related to the project (i.e. the funding is intended to support young researchers or infrastructure buy, etc.) but after further thinking I'm not anymore sure that this is needed. When such level of details is known the Funding entity will represent a specific contract and it would make much more sense to store the "constraints" or the purpose of the Funding directly inside its representation that over the relation to the project.

So I would suggest to simply deprecate the <Funded /> block and introduce a new

<Fundings>
       <Funding id="...1">
                  ...
       </Funding>
       <Funding id="...2">
                  ...
       </Funding>
                 ...
        <Funding id="...N">
                 ...
        </Funding>
</Fundings>
