This document provides an overview of Generic Enablers in the FIWARE platform. It describes Generic Enablers as reusable building blocks that provide common functions across multiple use cases and sectors. The Generic Enablers are divided into 7 technical chapters, including data/context management, interfaces to network and devices, security, and applications/services. Specific Enablers are also described as components that offer domain-specific functions for areas like manufacturing, media, healthcare, energy, and agrifood.

Overview of Generic Enablers

2. Introduction
The FIWARE Platform comprises a set of technological “Generic Enablers” which are considered general
purpose and independent from any “usage area”
Generic Enablers provide open interfaces:
to Application Developers (APIs)
to support interoperability with other GEs
FIWARE Reference Architecture
Build with other Generic Enablers

3. Introduction
FIWARE assembles a set of building blocks that ease creation of smart Internet Applications
These blocks are called Generic Enablers
They offer reusable and common shared functions serving multiple use cases in various sectors
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
available FIWARE GEis published on the FIWARE Catalogue

4. The 7 Technical Chapters
FIWARE GEs are divided into 7 technical chapters:
1. Cloud Hosting
2. Data/Context Management
3. Interfaces to Network and Devices (I2ND)
4. Advanced Web-based User Interface
5. Security
6. Internet of Things
7. Applications/Services and Data Delivery

5. 1. Cloud Hosting
IaaS Resource Management - to provision VMs (associate compute, storage and network resources)
Monitoring - to allow incorporating monitoring and metering mechanisms
Object Storage - to provide robust, scalable object storage functionality
PaaS Manager - to enable multiple deployment architectures (tiers)
Policy Manager - to provide the basic management of cloud resources based on rules
Self-Service Interfaces - to support for the users of cloud to manage their services and resources
Software Deployment & Configuration - to support automated deployment of software

6. 2. Data/Context Management
BigData Analysis - to allow the deployment of private computing clusters based on Hadoop ecosystem
Complex Event Processing - to analyze event data in real-time, generate immediate insight and enable
instant response to changing conditions
Publish/Subscribe Context Broker - to manage the context information
Stream-oriented - to provide an abstraction layer for multimedia capabilities, allowing non-expert
developers to include interactive media components to their applications
Network Information and Control – to enable the abstraction and virtualization of network resources and
functionalities
3. Interfaces to Network and Devices

7. 4. Advanced Web-based User Interface (1 of 2)
2D-UI - handles generic web user interface
2D/3D Capture - capture contextual information related a 2D 3D scene
3D-UI-XML3D - an extension to HTML5 for declarative 3D content represented as a scene graph
3DUI-WebTundra - Web client for taking realXtend 3D virtual worlds into modern web browsers
Augmented Reality - a high-level API for HTML5 Augmented Reality applications
Cloud Rendering - to provide a generic way to request, receive and control a video stream of a remote 3D
application

8. 4. Advanced Web-based User Interface (2 of 2)
GIS Data Provider - to host geographical data and serve it in 3D
POI Data Provider - to make easy the search, the store by location
Interface Designer - to provide an easy-to-use full manipulator / editor of 3D objects within a scene
Real Virtual Interaction - to provide means for connecting real world devices consisting of sensors and
actuators in to augmented or virtual reality applications
Synchronization - presents a lightweight and generic network-synchronized dynamic scene data model
Virtual Characters - consists of an open standard and reference implementation for virtual characters on
the Web (to create, display and animate virtual characters)

9. 5. Security
Authorization PDP - provides an API to get authorization decisions based on authorization policies, and
authorization requests from PEPs
Identity Management - covers a number of aspects involving users' access to networks, services and
applications, including secure and private authentication from users to devices, networks and services,
authorization & trust management, user profile management, privacy-preserving disposition of personal data,
Single Sign-On (SSO) to service domains and Identity Federation towards applications
PEP Proxy - together with Identity Management and Authorization PDP GEs, add authentication and
authorization security to your backend applications
Security Monitoring - to manage the Security Management System

10. 6. Internet of Things
Backend Device Management - IDAS - to provide API for M2M application
Configuration Manager - IoT Discovery - to register the availability of Things and Sensor devices
Configuration Manager - Orion Context Broker - to provide the NGSI9 interfaces
Gateway Data Handling GE - EspR4FastData - to process data in real time
Protocol Adapter - MR CoAP - to allow to plug devices
IoT Broker - lightweight and scalable middleware component that separates IoT applications from the
underlying device installations

11. 7. Applications/Services and Data Delivery
Application Mashup - Wirecloud - to build on cutting-edge end-user development, RIA
Marketplace - to provide functionality necessary for bringing together offering and demand for making
business
Repository - to provide a consistent uniform API to USDL service descriptions
Revenue Settlement and Sharing System - is in charge of distributing the revenues originated by the
usage of a given service among the involved stakeholders
Store - WStore - to sell services to both consumers and developers of Future Internet applications and
services and for end-to-end managing of offerings and sales

12. Specific Enablers (SEs)
A Specific Enabler (SE) is a component similar to a GE which offers functions relevant to domains
specific, for example manufacturing, media, eHealth, energy and agrifood.
