# SAREF4AUTO ontology and semantics

## Introduction and overview

The present document has been developed in the context of the STF 566, an ETSI specialists task force that was established with the goal to extend SAREF for the domains of Automotive, eHealth/Ageing-well, Wearables and Water ([https://portal.etsi.org/STF/STFs/STF-HomePages/STF566](https://portal.etsi.org/STF/STFs/STF-HomePages/STF566)). In particular, the present document is a technical specification of SAREF4AUTO, an OWL-DL ontology that extends SAREF for the Automotive domain. 

The intention of SAREF4AUTO is to connect SAREF with existing ontologies (such as W3C SSN, W3C SOSA, GeoSPARQL, etc.) and important standardization initiatives and ontologies in the Automotive domain, as mentioned in the associated SAREF4AUTO requirements document ETSI TR 103 508 [i.1], including: 

* ETSI TC ITS for V2V communications. 

* The SENSORIS data model [i.2] ([https://sensor-is.org/](https://sensor-is.org/)) for exchanging data between vehicles and cloud services.

* The DATEX II standard [i.3] for information exchange between traffic management centres, traffic information centres and service providers. 

* The DATEX II Parking Publications [i.4] for specifying information about parking sites and individual parking vehicles ([https://datex2.eu/implementations/extension_directory/parking-publications-extension-v10a](https://datex2.eu/implementations/extension_directory/parking-publications-extension-v10a)). 

To show the potential of SAREF4AUTO, the present document focuses on three examples, which are the "platooning", "Automated Valet Parking (AVP)" and "Vehicle environment with Vulnerable Road Users (VRU)" use cases. Various other examples exist in the Automotive domain. However, it was necessary to make actionable choices within the STF 566 timeframe and the available resources, thus those have been chosen as the three initial examples to create SAREF4AUTO. As a next step, it is recommended to further refine the proposed examples to add relevant sensors that are not considered yet, and also consider additional use cases to create new releases of SAREF4AUTO, following and extending the examples provided in the present document. As all the SAREF ontologies, SAREF4AUTO is a dynamic semantic model that is meant to evolve over time. Therefore, the stakeholders in the Automotive domain are invited to use, validate and provide feedback on SAREF4AUTO, collaborating with the SAREF ontology experts to improve and evolve SAREF4AUTO in an iterative and interactive manner, so that changes and additions can be incorporated in future releases of the present document.

The prefixes and namespaces used in SAREF4AUTO and in the present document are listed in Table 1.
