scope:

In e-health services, semantic data interoperability will enable the various systems to combine received information with other information resources and to process it in a manner that preserves meaning. The lack of semantic data interoperability between e-health systems is one of the major obstacles in the provision of cross-border and cross-sector e-health systems. [ITU-T Y.4563] identifies the requirements and functional model to support data interoperability in Internet of things (IoT) environments.

In accordance with [ITU-T Y.4452] and [ITU-T Y.4563], this Recommendation describes a framework to support web of objects (WoO) ontology based semantic data interoperability of e-health services by presenting:

- An overview of semantic data interoperability in e-health services;

- Requirements to support WoO based semantic data interoperability in e-health services;

- A functional model to support WoO ontology based semantic data interoperability;

- WoO based semantic data interoperability provisioning in e-health services.
