Liaison Statement from W3C Web of Things to ITU-T SG-20

Dear ITU-T/SG20 Members:
## CCing GyuMyoung and Cristina directly to make sure

We represent the W3C Web of Things (WoT) Working Group, and would like
to engage with SG20 to align our standards around IoT. In particular,
the current W3C WoT architecture is mostly but not entirely aligned with
the system described in the ITU-T documents on WoT, such as ITU-T Y.4400
(Framework of the web of things), ITU-T Y.4414 (Web of things service
architecture) and also the ITU-T documents related to the web of
objects, such as ITU-T Y.4452 and ITU-T Y.4415. Recently, the W3C WoT WG
has published a W3C Recommendation on a “Thing Description”, a metadata
representation using Linked Data and based on JSON-LD, but the current
ITU-T WoT metadata description is based on WSDL. We would like to
propose a meeting with relevant members of SG20 to identify potential
concrete steps toward alignment. Since data and metadata management is
central to this, this meeting should involve ITU-T members interested in
matters of data processing and management, for example, those working on
Q4 [1] and the DPM framework.

We look forward to hearing from you soon.

Sincerely,

For the W3C WoT IG/WG, as represented by 
Michael McCool, WoT IG/WG co-chair, Intel and
Sebastian Kaebisch, WoT IG/WG co-chair, Siemens;
Kazuyuki Ashimura, W3C WoT IG/WG Team Contact
