FIWARE components can be used to implement the core components of an Industrial Data Space (IDS), including the context broker and connectors. The FIWARE context broker and NGSI interfaces allow context information to be published, queried, and subscribed to, and can form the basis for communication between IDS connectors. Both organizations aim to have their specifications and architectures remain compatible so that a valid open source implementation of the IDS architecture can be built using FIWARE generic enablers.

4. FIWARE NGSI: Basic interaction
§ Context Producers publish context information by invoking the
updateContext operation on a Context Broker.
§ Context Consumers can retrieve context information by invoking the
queryContext operation on a Context Broker
3
Bus = “X”, location = (x, y)
updateContext
Context Producer
Context Consumer
queryContext
FIWARE Context Broker

5. FIWARE NGSI: Context Providers
§ Context Providers can be registered to the Context Broker as “holders” of
certain context information.
§ A Context Broker will invoke the queryContext or updateContext operations
exported by Context Providers whenever they are queried for, or asked to
update, context information they hold
4
Bus = “X”, location = (x, y)
queryContext / updateContext
Context Provider
(provider-x)
Context Consumer
queryContext / updateContext
registerContext (provider-x,
registration_data, duration, id)
)
FIWARE Context Broker

6. FIWARE NGSI: Subscription to notifications
§ Context Consumers can be subscribed to reception of context information
complying with certain conditions, using the subscribeContext operation a
ContextBroker exports. Such subscriptions may have a duration.
§ The Context Broker notifies updates on context information to subscribed
Context Consumers by invoking the notifyContext operation they export
5
Bus = “X”, next_stop = “A”, arrived = “Yes”
updateContext (context_info)
Context Producer
Context Consumer
(consumer1)
notifyContext (id, context_info)
Id = subscribeContext (consumer1,
condition, duration
)

12. IDS and FIWARE: collaboration to accelerate delivery of a
common vision
§ It is a common goal that a valid open source implementation of
the IDS Architecture can be based on FIWARE, compatible with
FIWARE Architecture principles:
• IDS does not intend to incorporate elements within the
specification of the IDS Architecture that prevent
development of a valid implementation of such
architecture using core FIWARE Generic Enablers
• the FIWARE Foundation will work towards making sure
that core FIWARE Generic Enablers can be integrated
together to build a valid open source implementation of the
IDS Architecture
§ Both organizations will:
• collaborate on the development of domain data models
• collaborate on and communicate about the development of
their respective specifications and architectures to keep
them compatible
