The IESG has received a request from the Constrained RESTful Environments WG (core) to consider the following document: - 'Media Types for Sensor Measurement Lists (SenML)' <draft-ietf-core-senml-13.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2018-03-30. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract This specification defines media types for representing simple sensor measurements and device parameters in the Sensor Measurement Lists (SenML). Representations are defined in JavaScript Object Notation (JSON), Concise Binary Object Representation (CBOR), eXtensible Markup Language (XML), and Efficient XML Interchange (EXI), which share the common SenML data model. A simple sensor, such as a temperature sensor, could use one of these media types in protocols such as HTTP or CoAP to transport the measurements of the sensor or to be configured. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-core-senml/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-core-senml/ballot/ No IPR declarations have been submitted directly on this I-D.
