FIWARE Toolbox Overview
• What we have worked out in CPaaS.io
• 4 new components
• 5 enhanced components
• 2 supporting tools
• Status
• Fully integrated with existing FIWARE GEs
• FIWARE-based Platform instance for CPaaS.io
• Validated by 3 use cases: Smart Parking,
MyEvents, Waterproof Amsterdam
• Four paths to Sustainability
• Delivered open source projects
• Promoted as new GE in FIWARE community
• Became new standardization
• Further exploited in the follow-up projects

IoT Broker, IoT Discovery, KnowledgeServer
• IoT Broker is a lightweight and scalable middleware component
that separates applications from the underlying device installations
• IoT Broker has been improved within CPaaS.io project in order to
automatically handle historical information through metadata
elements, integrated with
• IoT Discovery (ConfMan) is responsible for discovering the availability of context
and it serves as a registry of FIWARE NGSI context providers
• IoT Knowledge Server adds semantic information into NGSI messages and
enhance these NGSI messages with semantic reasoning
• These components were validated in the Waterproof and MyEvents
use cases, and also Dashboard Application.

IoT Broker, IoT Discovery(ConfMan), and KnowledgeServer are open-source projects
maintained and promoted mainly by NEC Laboratories Europe and the open-source
community. Source code is available on GitHub.
Outlook beyond the project

STH Comet
• Short Time Historic (STH, aka. Comet) is a component of the
FIWARE ecosystem in charge of managing historical raw and
aggregated time series information about the evolution in time
of context data
• STH Comet has been improved within CPaaS.io project to support
metadata information. A patch has been developed and is under
review by the maintainer
• It works with the latest version of Orion Context Broker to support
CPaaS.io use cases, such as the CPaaS.io dashboard
Orion and STH Comet are part of the FIWARE Platform and can be supported by resources from the
FIWARE foundation. Promotional activities are performed by FIWARE members and also directly
promoted by the European Commission through the Connecting Europe Facility framework.

NGSI-LD Broker
• Middleware implementation for the new NGSI-LD API
for Context Information Management (CIM)
• NGSI-LD has been standardized by the ETSI Industry
Specification Group for cross-cutting CIM
• This is a new component, developed from scratch and
it crosses three layers of CPaaS.io architecture
• Combines data ingestion, virtual entities and semantic data
• NGSI-LD Broker enables support of linked data and semantic interoperability
through heterogeneous context sources and consumers
• NGSI-LD supports property graphs and relationships that can be leveraged to Knowledge Graphs,
providing a groundwork for AI models and analytics
This component is still under development and the business model is currently under discussion.
NGSI-LD Broker will be used in other EU projects like AUTOPILOT and SynchroniCity. FIWARE
Foundation has already announced to move the open source ecosystem to NGSI-LD specification.

FogFlow GE: a new official FIWARE GE
FogFlow has been officially approved as a new open source FIWARE Generic Enable (GE)
1) source code is available on GitHub; 2) it is an open source FIWARE Generic
Enabler for IoT Edge Computing in the FIWARE community; 3) it is currently used
in Fed4IoT, which is a new EU-Japan project
Usage from external partners
Usage from CPaaS.io partners in the follow-up projectsDetailed tutorials, tour guide, training materials

Deployment Tool
• Reactive Web Application for Managing IoT Deployments
• Inventory Management, People and Groups, Event and Venue
Creation, Mobile Deployments, Map-based Static Deployments
• Fully RDF-based extending Semantic Sensor Network (SSN) ontology
• Significantly extended in CPaaS.io to support its use cases
• Used for metadata enrichment and historic queries
• Deployment part of SSN ontology significantly extended
for practical use
Deployment Tool, Knowledge Base and ontology already adopted and further
developed by AGT development. Deployment ontology considered for public
release.
Enhanced component

NGSI to RDF Mapper
• Enables semantic interoperability by converting
NGSI updates to RDF triples
• Synchronizes configurable sub set of NGSI updates
in real-time using NGSI subscriptions
• Writes converted triples in configurable triple store
• Developed from scratch to support semantic
interoperability of CPaaS.io
As part of IoTCrawler considered to be extended to 1) convert NGSI-LD updates to
existing RDF vocabularies 2) support conversion from existing RDF vocabularies to
NGSI-LD updates. IoTCrawler will release its core components as OSS.
New component

Security Components
• Identity Management: KeyRock. Extended to register devices
• Authorization Enabler: Uses XACML and DCapBAC
• Capability Token (authorization token) is issued by Capability Manager
• PEP_Proxy: Enforcement of authorization policies
• Validates Capability Token
• It also enables the encryption of the information to be stored using CP-ABE
• Personal Data Store (PDS)
• New development under this project to store personal information.
• Federation of PDS also provided thanks to OIDConnect.
• Integrated with Security components
The distribution can be managed thanks to Github repositories, as well as by
promoting them to FIWARE Generic Enablers and presenting them in fora such
as FIWARE Summit

LoRaWAN to NGSI bridge
• MQTT client TTN client that transform from TTN uplinks and downlink to
NGSI V2
• Fill in the attribute with the right physical unit.
• Can be deployed in standalone or be use as a library
• Include an HTTP server for IP devices
• Will be updated to support TTNv3 API
The bridge will be open sourced on github and communicated to the community.
It might be part of the webhook integration of V3 and so available on TTN
console, command line interface, and API.

Grafana NGSI Plugin for Visualisaiton
• This newly developed component establishes the data connection between the
STH Comet component and the visualization tool Grafana.
• The component:
• transforms GUI settings made by the user in Grafana to NGSI queries
directed towards STH Comet.
• reads query results from STH Comet
• transforms NGSI response to Grafana Query Response Format
and sends it to Grafana for visualization.
• The Grafana NGSI Plugin supports any kind of data time series,
but also supports additional meta-data, e.g. geographic locations
for visualization of maps .
Grafana NGSI Plugin is published under an open-source license. Its source code is
available on GitHub and can be easily adapted to any other project using FIWARE
NGSI with the need to visualize the data.
Supporting tool

Android App
• Enable end user to interact with CPaaS
• Login and logout to the PDS
• Creation of a new CPaaS.io user account
• Major Functionality
• Review/editing of personal data
• Participate in Crowdsourcing projects
• Publishing of sensor data (e.g. from mobile phone sensor) to FIWARE
• Visualisation of sensor data from crowdsourced data sets
The Android app will be further developed and used as a starting point to some
Master and Undergraduate projects at University of Surrey with additional
support of the FIWARE eco-system.

out of the box
FIWARE Toolbox
validated with 3 use cases in CPaaS.io
(Smart Parking, MyEvents, Waterproof Amsterdam)
and 2 recent applications
Whitepaper as the
guideline for users

Conclusion
• 4 new components have been introduced to CPaaS.io platform
• 5 components have been enhanced to address CPaaS.io use cases
• Pre-existing components have been integrated and validated via 3 real
use cases and 2 supporting tools
• New standard NGSI-LD, new GE, and lots of OSS contributions brought
into FIWARE ecosystem
Outlook beyond the project
Most of them are available as OSS projects. Those components will be sustained
through GitHub services and the OSS community. Components found in FIWARE
Catalogue are strongly supported and promoted by FIWARE foundation and its
members (organisations and individuals). Some components are going to be
used in EU(-Japan) projects like Fed4IoT, Synchronicity, and IoTCrawler.
