As an open source API to publish, request or subscribe to data and its context information; djane value proposition is to ease data sharing and integration. It addresses several facets of data integration and data economy:

  • Open data such as air quality, street maps or traffic

  • Commercial data for mobility, granular weather and advertising of events

  • IoT including building, energy or water sensors

  • Usage information for optimizing, debugging and relationships analysis

  • Artificial intelligence to build recommendations and derive insights

Additionally djane is not linked to a particular IoT or data platform. It is designed to work with any platform.

Let's face it: data integration sucks!

Any ontology

djane implementation has been designed to allow instantiation of any ontology, with initial focus on SAREF. djane is designed to scale for big data setups

Publish & Subscribe

Data producers can publish JSON-LD data as they get generated. data consumers subscribe to receive data as they get generated without the hustle of using different APIs/data formats

Security & Privacy

Access control policy govern who can receive which data and in which context, according to privacy principles. state of the art security ensures the system is end to end resilient against threats.

They trust us

Christophe COLINET
Smart City Project Manager with Bordeaux Métropole

We are working on a number of Smart City applications within Bordeaux Métropole. We concluded that a horizontal and standard-based approach is unique in extending and scaling those deployments while also avoiding lock-in. NGSI-LD provides a nice complement to our oneM2M based deployments in particular to encourage entrepreneurs take part in our citizen-centric journey by leveraging our enriched data and building applications

Lindsay FROST
ETSI ISG CIM Chair

I'm delighted to see implementations of NGSI-LD API only a few months after the publication of the first specification. Open source helps expedite time to market of SDO specifications, creating a healthy ecosystem and paving the way for interoperability. NGSI-LD API is designed to bridge between systems and we are hoping in this year to build bridges with both the oneM2M partnership project and the W3C Web-of-Things community.

 

About

 

What is NGSI-LD?

NGSI-LD is an information model, representation format and an open API intended to make it easier for end-users, IoT platforms, open data sources (for example in smart city) and 3rd-party applications to exchange information. The information model leverages the Property Graph information model. The representation format chosen is JSON-LD, while the open API uses HTTP REST bindings.


Why an open source for NGSI-LD matters?

Building a sustainable data economy (e.g. to support the EU Digital Single Market) needs a standard specification for exchanging data, be it for open data or commercial data. The value proposition is in reducing integration costs for projects involving exchanging data among a large number of entities. While important, a specification may not be enough for proliferation of interoperable implementations and deployments. An open source is equally important to ensure time to market of interoperable products and support a true and sustainable data economy. djane has the ambition to attract a community of developers to further the above mentioned goals.
