Context Broker Services
The current version of the specifications of the FIWARE NGSI API are the FIWARE NGSI-LD API specifications.
In 2016, the European Commission published The 2016 Rolling Plan for ICT Standardisation in which it requested ETSI create a ISG (Industry Specification Group) aimed at definition of a standard Context Information Management API with FIWARE NGSI as candidate. ETSI created this dedicated ISG beginning of 2017 resulting in a new standard, NGSI-LD, in November 2018. This API specification is compatible with the FIWARE NGSIv2 API specifications supported by the FIWARE/CEF Context Broker, adding new features bringing support to Linked Data.
More information about the cross-sector Context Information Management (CIM) ISG at ETSI can be found in the portal.
