The datameet maps repository has undoubtedly been the most widely used dataset that we have produced and is often the go to resource for India boundaries
https://github.com/datameet/maps
Most of the data is currently licensed as CC-by-sa 2.5 and its not clear if there was a strong reason to adopt that as the default license many years ago. In the spirit of open data, it might make more sense to drop the share alike clause and adopt CC-by 4.0 as the preferred license where the only condition is attribution, This will allow much greater reuse of these datasets and promotion of the DataMeet community.
