scope:

This Recommendation addresses the requirements and functional model for data interoperability in Internet of things (IoT) environments. The scope of this Recommendation covers several key requirements with respect to data interoperability in IoT environments and many important elements to fulfil these requirements. Specifically, this document covers the following:

- Overview of data interoperability in IoT environments;

- Requirements to support data interoperability;

- Functional model to support data interoperability;

- Functional components of the semantic mediation function;

- Functional components of the syntactic mediation function;

- Functional components of the object abstractions representation mediation function;

- Functional components of the interoperable data repositories.

NOTE 1 - For data interoperability with the web of object (WoO) based on [ITU-T Y.4452] see Annex A

NOTE 2 - For data interoperability approach of semantic and non-semantic data see Annex B.

NOTE 3 - For data interoperability example through semantic mediation see Appendix III.
