Hi Devdatta,
The platform is still work in progress. It was an initiative under the smart cities fellowship programme led by me and two others. It is currently backed by the National Institute of Urban Affairs. We are pitching it to be a one stop shop for all urban datasets at NIUA. As NIUA has a huge corpus of datasets (geospatial and others), we will be opening up more of these datasets in the coming days.
Reason for using CC0 1.0 in some of the datasets:
Although all the datasets on the platform belong to one or the other urban local bodies, the source for some of these datasets might not be a government body. So the rule we have been following for attaching a license is that all datasets procured from any govt body is licensed under Govt Open Data License, datasets aggregated from open sources are given the same license thats available at the source (mostly CC0 1.0) and non-govt. sources without any license are left as "License not specified".
It's not a funded project (yet) and is built on an open source stack so some links are broken. We were initially planning to create an open licensing platform where cities can drag and drop pre-built clauses to create custom data sharing licenses according to their needs. Most cities are not comfortable releasing the data under the open data license and hence we see poor quality datasets on most govt platforms. The
license.dataspace.mobi was supposed to redirect to that platform but it was never built.
Not a legal expert so any feedback on licensing or the overall platform is more than welcome.
