[The technical specification ETSI TS 103 410-11](#[0]) is a technical specification of SAREF4LIFT, an extension of SAREF (ETSI TS 103 264 [[1]](#[1])) for the Smart Lifts domain. Clause 6.1 of [the technical specification ETSI TS 103 410-11](#[0]) shortly introduces a high level view of the envisioned SAREF4LIFT semantic model and modular ontology, with the retained concepts (i.e. classes) and their relations. 

# SAREF extension for the Smart Lifts domain

SAREF4LIFT has been specified and formalized by investigating related resources in the Smart Lifts domain, as reported in ETSI TR 103 546 [[i.1]](#[i.1]) and ETSI TS 103 735 [[i.2]](#[i.2]). Therefore, SAREF4LIFT shall both:

* allow the implementation of a limited set of related use cases already identified in ETSI TR 103 546 [[i.1]](#[i.1]); and

* fulfil the requirements provided in clause 5, mainly the ontological ones that were mostly taken as input for the ontology specification.

The present document is a technical specification of SAREF4LIFT, an extension of SAREF for the Smart Lifts domain. This SAREF extension is based on a limited set of use cases and existing data models identified within available initiatives that was detailed in previous documents ETSI TR 103 546 [i.1] and ETSI TS 103 735 [i.2]. The work was initially conducted (in 2021) in the context of the closed STF 602 ([https://portal.etsi.org/STF/STFs/STF-HomePages/STF602](https://portal.etsi.org/STF/STFs/STFHomePages/STF602)), which was established with the goal of creating SAREF extension for the domain mentioned above, i.e. Smart Lifts. This work has been developed in close collaboration with the industrial world and alliances.

SAREF4LIFT is an OWL-DL ontology. For embedded semantic analytics purposes, SAREF4LIFT shall be designed using the modularity principle and can thus be mainly described by a set of knowledge modules. All these SAREF4LIFT modules are fully detailed in clause 6.2 of [the technical specification ETSI TS 103 410-11](#[0]). 

The prefixes and namespaces used in SAREF4LIFT and in [the technical specification ETSI TS 103 410-11](#[0]) are listed in Table 6.1-1.

The related initiatives and use cases considered for the intialdevelopment (in 2021) of the SAREF4LIFT extension are the ones reported previously in ETSI TR 103 546 [i.1] and ETSI TS 103 735 [i.2]. Such related initiatives and use cases are not repeated in the present document. Hence, the reader can rely on those references for further details.

The present document is a major 2024 revision of SAREF4LIFT ontology extension, developed in the context of the STF 641 ([https://portal.etsi.org/xtfs/#/xTF/641](https://portal.etsi.org/xtfs/#/xTF/641)), using updated reference ontology patterns specified in ETSI TS 103 548 [9] to solve the harmonization needs identified in ETSI TR 103 781 [i.5], with updated development framework and tools defined in ETSI TS 103 673 [i.6].
