This document incorporates data structures used by all other data domains of Transmodel. It is composed of the following data packages:
- versions and validity
- responsibility
- generic framework
- reusable components
- explicit frames referring to generic data.
The data structures represented in this part are either generic patterns that can be explicitly reused in other domains (e.g., a generic model for version frames, a generic grouping mechanism, etc.) or are referenced by different other parts (e.g., service calendar model).
This document itself is composed of the following parts:
- main document representing the data model for the concepts shared by the different domains covered by Transmodel (normative)
- Annex A containing the data dictionary and attribute tables, i.e., the list of all the concepts present in the main document, together with their definitions (normative)
- Annex B, indicating the data model evolutions (informative),
- Annex C, presenting the Transmodel development history (informative),
- Annex D, describing all conventions, methodology and notations for conceptual modelling (informative),
- Annex E, providing a clear overview to help readers understand the core principles, structure, and purpose of Transmodel (informative),
- Annex F, providing information on the Functional domains and Modes of operation (informative).
- Annex G, providing details of the significant technical changes between this document and EN 12896-1:2015 (informative).
