BIG IoT API design - first release

D3.1.a This deliverable provides the design and detailed specification of the BIG IoT API. Outcome of this deliverable will be the central basis for the implementation work of D3.4 as well as an important input to the work on marketplace and software infrastructure in WP4 as well as the realization of use cases in WP5. Following the agile project management approach, this deliverable will have three versions, starting with D3.1.a that is due in M12. The second and third versions (D3.1.b at M21 and D3.1.c at M30) of the BIG IoT API will build up on their preceding versions and their design will consider lessons learned from implementing and utilizing the previous version. D3.1.a contributes to MS1.
