prEN 12896-8

Scope

Transmodel is composed of 10 parts (see above). This work item consists in the revision and update of the documentation of the Public transport reference data model – Part 8 (Transmodel – Part 8). The update consists basically of the following types of actions: a. Simplication of Part 8 based on the revision of Part 1: several functional extensions of Transmodel took place since the last publication of EN12896 (in 2016 and 2019). The functional extensions elaborated until 2019 generated additional common concepts which have already been published in the relevant documents. These additional common concepts are now integrated into Transmodel - Part 1 and thus removed from Part 8. b. Updates/extensions of Part 8 as a consequence of • Work presented in TR17370:2019. This TR provides a list of KPIs calculated using operational raw data. The action consists here to provide data model extracts, representing the raw data needed for several KPIs (listed in TR17370:2019), The extracted sub-models are based upon the (already existing) "Loggable object model" and will complete the 2 examples published in the current version of Part 8. c. Ensuring coherence of the Transmodel eco-system. Several updates of Transmodel- Part 8 result from the discussions lead with the OpRa group and intend to ensure coherence with the OpRa Technical Specification.
