Dear Member of the NGSI-LD Working Group in FIWARE, I just created the mail below and sent it out to the FIWARE ecosystem mailinglist. It is awaiting moderator approval. With that mail we like to announce the NGSI-LD working group in FIWARE to the FIWARE ecosystem. Feel free to forward to the mail to respective interested parties and projects. Kind regards Ernoe From: Ernoe Kovacs Sent: Freitag, 10. August 2018 01:49 To: 'fiware-ecosystem at lists.fiware.org' Subject: Announcing the NGSI-LD working group in FIWARE Dear FIWARE enthusiasts, global digitization and related accelerated deployments of IoT, SmartCity and Data Lake solutions can be seen everywhere. This drives the need to capture and integrate diverse and constantly changing data sources and analytic results . Providing a comprehensive, robust and open approach using standards is critical to the continued success of FIWARE. Next generation Context Management needs to evolve to address semantics, linking of data, and provide appropriate Query Languages. Otherwise there is a risk of falling behind. The ETSI ISG CIM (Industry Specification Group on Context Information Management), with strong support from FIWARE players, has developed a first version of the NGSI-LD API – an evolution of the FIWARE NGSI context interfaces. We now want to discuss in FIWARE how to evolve FIWARE GEs to support NGSI-LD. Advantages of NGSI-LD in a nutshell: Formal Specification - being based on an ETSI Group Specification, NGSI-LD<http://www.etsi.org/deliver/etsi_gs/CIM/001_099/004/01.01.01_60/gs_CIM004v010101p.pdf> becomes attractive to an even broader audience, including smart cities and governmental organizations including the European Commission. The LD in NGSI-LD stands for ‘Linked Data’ and enables easier integration with a plethora of information sources. Semantic Data and Upgrade Path - while the serialization of NGSI-LD is still JSON and is very similar to the NGSIv2 serialization, the LD-Aspect comes in with a special “@context” element that can also be integrated into an HTTP header. Linked Data/Relationships - The underlying information model has been extended to explicitly support relationships between entities resulting in an entity graph. The “@context” allows linking to standardized vocabularies without compromising the succinct JSON representation of the information itself. Information / Documentation More information about and motivation for NGSI-LD can be found in the attached presentation. How to participate… We have now created the fiware-ngsi-ld at lists.fiware.org<mailto:fiware-ngsi-ld at lists.fiware.org> mailing list, where we want to start discussing the evolution of FIWARE towards NGSI-LD. If you want to be part of this journey, please subscribe to the mailing list via https://lists.fiware.org/listinfo/fiware-ngsi-ld. Please share this information with interesting parties. Timeline We expect substantial pickup of the discussion after the summer break. But of course, technical discussions as well as questions can already start now. Please use the mailinglists Best regards - Ernö Kovacs on behalf of the FIWARE roadmap team ____________________________________________________________ Dr. Ernö Kovacs エルノー・コヴァーチェ NEC Laboratories Europe GmbH IoT Platform Research Kurfürsten-Anlage 36 | D-69115 Heidelberg, Germany E-Mail: ernoe.kovacs at neclab.eu<mailto:ernoe.kovacs at neclab.eu> <mailto:ernoe.kovacs at neclab.eu> Tel. +49 6221 4342 – 131 |Fax. +49 6221 4342 – 115 Mobile: +49 163 2086046 Registered at Amtsgericht Mannheim, Germany, HRB728558 __________________________________________________________ -------------- next part -------------- An HTML attachment was scrubbed...
