Startups that want to design innovative products and services using data that's accessible via the web now have better data mining tools, thanks in part to startups like the award-winning import.io. Meanwhile, the recent settlement between U.S. startup People+ and AOL around accessing the entire Crunchbase database via API for a Google Glass app means there could be greater clarity for startups around data usage rights when creating commercial ventures. ProgrammableWeb spoke with import.io co-founder and chief data officer Andrew Fogg and Electronic Frontier Foundation staff attorney Mitch Stoltz to discuss commercial trends in data scraping and developer rights in using data via APIs for business product design.
