First look into the awards category of #OpenAlex. From a German perspective, it seems pretty useless so far. Only EU projects seem to be connected to German research institutions. And there is only one #DFG project with at least one work connected after 2003: https://openalex.org/awards?page=1&filter=funder.id:f4320320879,funded_outputs_count:1-,start_year:2003- - and only connected works for 2000-2002. Lots of DFG projects have strange titles. BMFTR projects have neither dates nor titles: https://openalex.org/awards?page=8&filter=funder.id:f4320321114&sort=start_year:desc
There is a lot to improve.
