Yeah. I was thinking of a crowdsourced marketplace platform which follows a particular standard so all dataset supports major ML platforms, API support for programming languages for preprocessing huge datasets etc.People can prepare and sell /buy datasets. This can bring people from various streams together to solve really major issues using the data.
what is a 'particular standard for data'
Many datasets available online does not clearly tell the quality of data. So I think, having a particular standard of quality can really help.
