FIWARE Catalogue
Rich library of general purpose functions offered as APIs (Generic Enablers or GEs) with reference implementations
Organized in chapters in FIWARE catalogue ( )
Public, royalty-free, open source GEs
Applications are implemented as combination of GEs, remote function calls, as RESTful architectures
Domain Specific Enablers (DSEs): complex or domain specific functionality
Are combined with GEs to build applications in specific domains (energy, media, smart manufacturing, health, wellbeing, agrifood)

FIWARE Chapters
Data/Context: Easing access, processing, analysis of context information
Internet of Things (IoT): connect things
Web-based User interface
Security: trustworthy delivery and usage of services
Network: build communication efficient distributed applications
Architecture: Create, publish, consume services

15. Security: Identity Management (IdM KeyRock)
IdM is key on any architecture, supports
users' access to networks, services and applications,
Secure authentication from users to devices, networks, services,
Authorization management,
user profile management,
privacy-preserving disposition of personal data
Single Sign-On (SSO) to service domains
Unique authentication/authorization system of all actions, several applications can be linked to IdM,
benefit for users is a single sign-on (SSO) to all these applications
Offers hosted user profile storage: Applications do not have to run and manage their own user data stores, but instead, can use the IdM user profile storage as a Software as a Service (SaaS)
FIWARE IdM complies with the OAuth2 standard described in RFC 6749

OAuth 2.0 Main Idea
Allows Internet users to login to 3rd party Web sites/services using their accounts in Google, Facebook, etc. but without exposing their password
The response includes an access token which the application can use to gain direct access to the provider's services
Works over HTTP
Access tokens are issued by an authorization server, the 3rd party uses the tokens to access the protected resources hosted by the resource server

“OAuth Roles
Resource Owner: the service who authorizes an application to access its account
Resource server: the resource server hosts the protected accounts, data or services
Client: is the application that wants to access the user’s account
Authorization server: verifies the identity of the user and issues access tokens

20. Data/Context: Publish/Subscribe Context Broker (Orion)
In a Data/Context scenario, this component mediates between consumer producers (e.g. sensors) and the context consumer applications (e.g. an smartphone applications reading information like measurements provided by the sensors)
Implementation of NGSI9, NGSI10 interfaces
Register context producer applications, e.g. a temperature sensor within a room
Update context information, e.g. send updates of temperature
Being notified when changes on context information take place (e.g. the temperature has changed) or with a given frequency (e.g. get the temperature each minute)
Query context information: The Orion Context Broker stores context information updated from applications, so queries are resolved based on that information.

Context Services, NGSI
A protocol developed by OMA (Open Mobile Alliance) to manage context information
Context information: describes status of applications, environment and situation
Context aware services adapt to user needs
NGSI provides operations like
Manage context entities
Access (query/subscribe) context entities
NGSI 9/10 protocol (RESTful interface) for exchanging context information
Registration of context information
One time queries for context information
Subscriptions for context information updates,
Notifications

26. Data/Context: Complex Event Processing (CEP)
CEP GE analyses event data in real-time, generates immediate insight and enables instant response to changing conditions
CEP GE reacts to situations rather than to single events
A situation is a condition that is based on a series of events that have occurred within a dynamic time window called processing context
Eg., temperature must be within [LowTemp, HighTemp]
Situations include composite events (e.g., sequence), counting operators on events (e.g., aggregation)
Allows for definition of CEP applications using a web user interface
