FIWARE = advanced OpenStack-based Cloud + rich library of Generic Enablers

Sustainability ensured

Driven by implementation

FIWARE Generic Enablers (GEs)

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.

FIWARE major differential features

• Federation of infrastructures (private/public regions)• Automated GE deploymentCloud• Complete Context Management Platform• Integration of Data and Media ContentData• Easy plug&play of devices using multiple protocols• Automated Measurements/Action Context updatesIoT• Visualization of data (operation dashboards)• Publication of data sets/servicesApps• Easy support of UIs with advanced web-based 3D and AR

capabilities• Visual representation of context information.

Web UI

• Advanced networking capabilities (SDN) and Middleware• Interface to robotsI2ND• Security Monitoring• Built-in Identity/Access/Privacy ManagementSecurity

Take the most of infrastructures while keeping costs lower and under control

VM provisioning

Gathering, publishing, processing and analyzing private and open data at large scale

Context management

• Context Management in FI-WARE is about management of Context data (aka Context Information)

• Context Information is always relevant to “entities”, although entities can be anything (applications, users, things, …)

• Orion Context Broker intermediates between context producers and context consumers

NGSI API

• REST API (XML & JSON rendering)• Additional “convenience” operations to ease some

operations

Context Availability Management (NGSI9)

• Register context sources (registerContext)

• Search for context sources (discoverContextAvailability)

• Subscribe to context sources availability notifications (subscribeContextAvailability, updateContextAvailabilitySubcription & unsubscribeContextAvailability)

Context Management (NGSI10)

• Update context information (updateContext)

• Query context information (queryContext)

• Subscribe to context information notifications (subscribeContext, updateContextSubcription & unsubscribeContext)
