It would be great to see negative numbers if the dataset metadata count goes down ever, e.g.:
If Department of Energy updates their /data.json in June 2017 and it was 3 less datasets included, the number on that table should read: -3 (ideally to a data.json change log or something)
Data.gov currently tracks how many new datasets are cataloged per month here: https://www.data.gov/metric/federalagency/dataset-published-per-month
It would be great to see negative numbers if the dataset metadata count goes down ever, e.g.:
Note: I understand that Data.gov does not host the data directly so it cannot monitor whether a dataset has been removed from the web, but adding this feature coupled with the broken links reports (https://catalog.data.gov/report/broken-links) will be helpful in following up with agencies on anything that appears to have gone missing.
