The very productive and well attended Technical Committee meeting on the 26th of August revolved around Working Group 1 – Data Centric – and its subgroups. It was an opportunity for everyone to take part in the discussions and share their views on the solid work done so far. Working Group 1 – working on requirements on how to write the technical specification with data centricity in mind – is scheduled to be completed by the end of 2020.
What is data centric?
This blog post summarizes it quite nicely:
“Data-centric refers to an architecture where data is the primary and permanent asset, and applications come and go. In the data-centric architecture, the data model precedes the implementation of any given application and will be around and valid long after it is gone.”
This blog post explains it in a similar way:
“A data-centric architecture has a permanent and primary core: Data. Applications and services are ephemeral, they live as long as they are useful. But Data is always there.”
With a work plan divided into three deadlines in September, October, and a final deadline at the end of 2020, the work in the group and subgroups is well underway. There are 3 subgroups:
- SG1: General design rules
- SG2: Data Centric
- SG3: MQTT
At the start of the meeting, Anders Fromell from ITxPT was assigned group leader for subgroup 1. Leaders of subgroup 2 and 3 are David Glendining and Sylvaine Roullier.

Subgroup 1 reported good progress and having landed in a functioning work structure, with an initial focus on the onboard structure.
Subgroup 2 concluded that it is important for everyone to understand what the data names refer to, which has led to the suggestion to create a dictionary for the data centric work.
Subgroup 3 talked about their work with recommendations regarding the MQTT version, message retention, and last will of a publisher.
ITxPT reported that there is a continuous high interest in labeling and that negotiations are underway for new lab and office facilities in Gothenburg.
