Dimensions (full access) was used to retrieve publications (publication type: articles) per funder per year:
8
Dimensions enables an indexed field search for funders (this search option is unfortunately not available in the free version)
9
The completeness of the retrieved publication list is influenced by a) coverage of publications in the database (to a large extent matching Crossref and PubMed) and b) detection of funder information (definitely not complete)
10
Funder information in Dimensions is based on publisher metadata, the mining of the acknowledgement section and are working directly with funders.

(Note: National Research Fund (NRF) from Luxembourg was not found to be listed as a funder entity in Dimensions)

Information on OA status was obtained using Unpaywall data
16
DOIs obtained through Dimensions were entered into Unpaywall Data's batch DOI lookup. The resulting .csv file was used to retrieve information on OA status. This comprises all forms of gold OA (pure gold, hybrid, and bronze) and all green OA (submitted versions, accepted versions and publisher versions of articles found in institutional or subject repositories).

20
By adding a column to the resulting spreadsheet that contains the follow formula, a column with OA-types can be generated:
21
=IF(C7="repository", "green", IF(C7="publisher",IF( L7=TRUE, "pure gold", IF( D7<>"", "hybrid", "bronze" )),"closed"))
22
23
OA-types were defined as follows:
24
Pure gold: Published in an open-access journal (as defined by inclusion in the Directory of Open Access Journals (DOAJ))
25
Hybrid: Free under an open license in a toll-access journal
26
Bronze: Free to read on the publisher page, but without an open license
27
Green: Accessible from a disciplinary or institutional repository (either as submitted version, accepted manuscript or publisher version)
