Several major updates to Common Data Index registry and right now it includes 9635 data catalogs, most of them are in US and it's geoportals/geocatalogs like ArcGIS Hub, ArcGIS server, #geonetwork and e.t.c. #CKAN is the most popular open data software.

My personal KPI about this registry is to reach at least 13000 data catalogs. It's the number of data sources of the Google Dataset search (GDS). Even if GDS consumes different data sources

The list of most public data portals software: CKAN, ArcGIS Hub, Geonetwork, Dataverse, OpenDataSoft, Socrata, NADA, and InvenioRDM. Geonetwork is usually popular but it's instances ain't simple to find, there is no single list of them, except the list that I do.

I've been manually analysing about 1.5k data portals and catalogues and I've found a few insights I'd like to share.

First of all, I see that up to 75% of all open government data is currently geospatial data. I see an increasing number of Geonetwork and ArcGIS Hub installations.

Second, I see a wave of open research data repositories with Dataverse, InvenioRDM and a lot of custom software.

I don't know yet what to do with all this knowledge. But maybe you have some ideas?
