My set that still needs confirmed validation is at: https://github.com/MBcode/ec/tree/master/test standard
and when finished should probably go into: https://github.com/earthcube/GeoCODES-Metadata/tree/main/metadata/Dataset json ;also after we sync up on order of what should go in, probably a few from one repo, then expand out w/my sampling from the notebook

I copied the test files and renamed them so they'd work with my github client (doesn't like the ':' in the file names?)
testing validation now, lots of issues to work on, I'll keep you posted. The files are at https://github.com/earthcube/GeoCODES-Metadata/tree/main/metadata/Dataset/json with names starting with 'MB_'

I ran the JSON dataset schema on the new files, notes on problems are in text files https://github.com/earthcube/GeoCODES-Metadata/tree/main/metadata/Dataset/json/validation . I fixed some of the problems and left others as test targets.

We have been running: geocodes_demo_datasets from sources that the drop-off testing has already found problems with, but we need just a few cases that are expected to fail in each stage/way that we test in that stage. So we can make sure every test is still working
