BIG IOT challenge

You will get access to BIG IoT Marketplace and API technologies

and access to mobility & environmental resources

to allow you to hack and play with parking, cars, environmental sensors, bicycles to develop sustainable and efficient way to live and travel in a smart city

for the development of new applications/services based on existing BIG IoT offerings and/or for the integration of data/services and development of new applications and services

in the various domains: Smart Mobility , Environment , Travelers experience, Bike sharing, charging, Eco-route.


Marketplace

Key task of a marketplace is to provide extended functionalities to enable the advertising, discovery, automated orchestration, and negotiation of services to facilitate their usage.

Marketplace is a B2B broker for access to IoT information and functions

Develop Business Models

All entities on Marketplace are semantically annotated to allow semantic queries

Offering registrations will be stored in marketplace backend

User can use the discovery function provided by Marketplace to look for the data/resources offerings

Developers, Web Infrastructure Manager, Creatives… (@ Smart City, @ Mobility Company) … wants to setup of Smart City services & Applications

BIG IoT Marketplace

BIG IoT Provider Lib

BIG IoT Consumer Lib

OD describesinterface.

OD used aspayload.

OD model for searchOffering Description (OD)


API By using open web API (offered here as a lib), IoT platforms and services

can provide their resources in a generic way.

Using the same API lib, IoT applications (but also services) can consume those resources very easily. In this way, the API lib helps in solving the today’s interoperability issues between IoT providers and consumers.

Once a platform or service is using the lib, their resources can be registered as offerings on the Marketplace.

For example, an IoT platform could offer data on the status of parking spots (occupied or available) within a city.

An IoT service could provide the functionality to reserve resources.

An application could access both with the BIG IoT API and combine them to enable reservation of parking spots.


Provider Side

Provide IoT Offerings. How do you connect your platform to the Marketplace in order to provide this data to other developers so they can use your data in their applications?

The Provider Lib offers the following main functionalities:

Authentication

Creation & Registration of offerings

Activation and de-activation of offerings

Providing access callbacks


offering.addInputData("longitude", "schema:longitude", ValueType.NUMBER).addInputData("latitude", "schema:latitude", ValueType.NUMBER).addInputData("radius", "schema:geoRadius", ValueType.NUMBER).addOutputData("longitude", "schema:longitude", ValueType.NUMBER).addOutputData("latitude", "schema:latitude", ValueType.NUMBER).addOutputData("dist", “mobility:distanceFromParkingSpace", ValueType.NUMBER).addOutputData("status", "datex:parkingSpaceStatus", ValueType.TEXT);offering.inRegion(BoundingBox

.create(Location.create(41.361, 2.082), Location.create(41.45, 2.252))).withPrice(Euros.amount(0.02)).withPricingModel(PricingModel.PER_ACCESS).withLicenseType(LicenseType.CREATIVE_COMMONS);


Consumer Side

Consume IoT Offerings. Assuming, you want to create an environmental monitoring service that should display temperature data on a web dashboard for different places in cities. Using the Consumer Lib, it is very easy to make your service use the Marketplace to query relevant data sources and access them.

The Consumer Lib offers the following main functionalities:

Authentication on a BIG IoT Marketplace

Querying the Marketplace to find relevant offerings

(Un-)Subscribing to offerings to be notified of any events regarding the offerings

Accessing offerings


OfferingQuery query = OfferingQuery

.create("DemoParkingQuery")

.withName("Demo Parking Query")

.withCategory("urn:big-iot:ParkingSpaceCategory")

.withTimePeriod(TimePeriod.create(new DateTime("2018-01-01T0:00Z"), DateTime.now()))

.inRegion(BoundingBox.create(Location.create(40.0,8.0),Location.create(45.0,12.0)))

.addInputData("schema:longitude", ValueType.NUMBER)

.addInputData("schema:latitude", ValueType.NUMBER)

.addOutputData("schema:longitude", ValueType.NUMBER)

.addOutputData("schema:latitude", ValueType.NUMBER)

.addOutputData(“mobility:parkingSpaceStatus", ValueType.TEXT)

.withPricingModel(BigIotTypes.PricingModel.PER_ACCESS)

.withMaxPrice(Euros.amount(0.5))

.withLicenseType(LicenseType.CREATIVE_COMMONS);


Offering Description & Semantic Models

Semantic Core Model

The semantic core model defines the vocabulary and structure required to describe Offerings and the context of resources.

The semantic models can be modularized according to their scope, as follow:

Organization module

Provider module

Offering module

Consumer module

Query module


Semantic Domain Models

While the semantic core model defines the core vocabulary and concepts, the Offering Descriptions (ODs) and Offering Queries also require domain independent and domain dependent vocabulary to describe the offerings. Therefore, domain dependent and independent semantic models are used to annotate the OfferingCategory and Input/Output Data of an Offering Description. Along with offering categorization and data modeling, the semantic domain model also defines the vocabulary to semantically annotate the domain dependent features of an offering.

At the moment, two domain models:

Mobility (Parking, Traffic, Bus, Charging,..)

Environment (Air Quality, Pollution, ..)
