 A FIWARE Generic Enabler (GE):
 Set of general-purpose platform functions available through APIs.
 Building with other GEs a FIWARE Reference Architecture.
 FIWARE GE Specifications are open (public and royalty-free).
 FIWARE GE implementation (FIWARE GEi):
 Platform product that implements a given GE Open Spec.
 There might be multiple compliant GEis of each GE Open Spec.
 At least one open source reference implementation of
FIWARE GEs (FIWARE GEris):
 Well-known open source license.
 Publicly available Technical Roadmap updated in every release.
 Available FIWARE GEis, GEris and incubated enablers
published on the FIWARE Catalogue.
