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 73... |
736e9a98ef6bb5efb3f13fd4a94e7db6 | 103 410-11 | 5 Requirements | The requirements presented in this clause 5 have been derived from the previously presented use cases. Even if not every requirement is useful for every use case, the different categories of requirements taken into account are expected to support at least the use cases described in ETSI TS 103 735 [i.2]. The associated... |

In Figure 6.2.1-1, classes directly imported from SAREF ontology are in light orange, classes directly imported from other SAREF extension ontologies are in green. While, classes developed for SAREF4LIFT are in blue and, finally... |
736e9a98ef6bb5efb3f13fd4a94e7db6 | 103 410-11 | 6.2.2 Systems and connections | This module specializes the SAREF4SYST ontology pattern for the Smart Lift domain. A Smart Lift system can be defined as a s4syst:System made by different components. This module defines the subcomponents that are part of Smart Lift. In particular, two subcomponents are denoted: the s4lift:SmartLiftEdgeComponent and th... |
