D2.2 - Open API Specifications Update

This is the updated version of the original document from M12. No reportable updates or modifications have been notified from participating partners, as the specifications are still being implemented in the pilots and no conclusions have been reached yet. A new section has been annexed in section 8.2, regarding existing open software, such as OGEMA, responsible for communication with proprietary energy generation/storage and monitoring solutions and vendor data formats. This document aims to address integration standards and support integration patterns to enable horizontal interoperability among various heterogeneous systems and business applications. Three sets of existing APIs will be described in this document: NGSI-LD API for the internal use between the components within the logical PLATOON architecture and external platforms Set of APIs for the relation of specific Marketplace components Specific set of APIs for the Data Analytic Toolbox component
