[Fiware-technical-committee] Presentation on LDES at the next TSC and working group towards evaluating the integration of LDES concepts in NGSI-LD

[Juanjo Hierro]

Hi everyone,

   In the last month, we at the FIWARE Foundation have held a couple of 
meetings with representatives of the Vlaanderen 
<https://www.vlaanderen.be/> initiative from Flanders, Belgium.

   This is a very interesting initiative which aims at creating a space 
for data sharing based on a number of agreed open standards.

   Concretely, they are advocating for the adoption of LDES (Linked Data 
Event Streaming) <https://semiceu.github.io/LinkedDataEventStreams/> as 
a main mean for sharing data.  LDES is based on the TREE hypermedia 
specification <https://treecg.github.io/specification/> and both are 
specifications adopted by the W3C.

   You can check these two good webinars to learn more about LDES and 
the vision behind:

  * https://www.youtube.com/watch?v=89UVTahjCvo&t=1111s (this
    presentation is part of a wider event, so I have provided a link
    that starts at the concrete presentation and you may not need to
    consider the rest of presentations coming after)
  * https://www.youtube.com/watch?v=Jp4ciO4Y63U (more detailed technical
    presentation which assumes you had view the previous)

   IMHO, the functionalities in LDES are not only complementary to what 
NGSI-LD brings today but provides a good basis on top of which NGSI-LD 
can be extended with capabilities that would allow consumers of data to 
query for "fragments" of context they will process locally but to which 
they will be synced through some sort of notification mechanism.  LDES 
can also be used for implementing advanced federation of context brokers.

   I have proposed the team of the Vlaanderen initiative to create a 
working group for analyzing further how LDES capabilities can be 
incorporated into NGSI-LD.  We, from FIWARE Foundation, will certainly 
join that group but I would like to propose others involved in NGSI-LD 
activities to join as well.   Goal would be to generate an initial 
proposal on how to incorporate LDES capabilities into NGSI-LD.  With 
such initial proposal, we would initiate the discussion within ETSI as 
it has happened with other new functions incorporated recently into 
NGSI-LD specs.

   I have invited the team of the Vlaandereen initiative to make a 
presentation on LDES during our TSC this Monday since the major topic 
for this TSC will be discussing about NGSI-LD evolution, therefore it 
made a lot of sense.  That could be a good start for kicking off the 
mentioned working group.

   @Martin: please plan the agenda considering we will devote 30 mins of 
the TSC for to make a presentation on LDES.   I suggest that we start 
with this item in the agenda.   We shall plan like 30 mins on LDES, 45 
mins to one hour on other NGSI-LD evolution plans and 30-45 mins to 
follow up on status of the different Context Broker implementations.

   Cheers,
