At a high level, how is data gathered by Parts.io? Is it manually entered? Provided from manufacturers? Do user's contribute? (http://community.parts.io/t/user-contributed-data-a-way-to-do-it-right/89)
More specifically, I'm not asking about the pricing information or risk information that Parts.io gathers (http://blog.parts.io/visualizing-parts-io-data/), but the actual data about a component itself. For example, operating temperatures for transistors, CPU frequencies for microcontrollers, etc. How does Parts.io typically source this raw component data?
