The Data Models and Ontologies Pillar shall:

host the Vehicle Data Project(VSS) ensuring a consistent vehicle data rule set & development of a vehicle data catalog
discuss and document a personal data model (PDM) and align with best practices of privacy and identity
host discussion on vehicle data concepts and related tooling

The Data Models and Ontologies Pillar may:

discuss interaction with other domain models Includes the following existing activities:•Vehicle Signal Specification project

Proposals for evolving VSS

The proposals below have been presented along the COVESA activities with the aim of restructuring (or extending) the data modeling tasks at COVESA, with a particular focus on improving and evolving VSS.

Proposal name	Author	Reference resources	Main idea(s)
Transforming from a vehicle centric data model to a domain agnostic information model	Ulf Bjorkengren (Ford)	Presented at COVESA AMM Porto (April 2023)
Defining the COVESA data modeling strategy and its associated artifacts	Daniel Alvarez (BMW AG)	Presented at COVESA AMM Porto (April 2023)	Use the right tool for the job. Do not try to cover multiple domains with only one tree. There are other types of data models that are more expressive than a tree. Use a standard language to express cross-references (e.g., RDF). Use ontologies to handle data integration and the identification of resources. Provide the mechanisms to sync a tree to an ontology, and standardise the steps to follow. Do you need a data model, or are you looking for a use-case specific data schema? For more details, see the extended description.
GraphQL schema as contract	Daniel Wilms (SPREAD GmbH)	Presented at VSS data modeling group on 01 Aug 2023
Integrating Vehicle Signals with VSS and Metadata	Alan Freedman (Ford)	Recording of Presentation Passcode: #+wbA5dy
Vehicle DATA Specification	Daniel Alvarez (BMW AG) Daniel Wilms (SPREAD GmbH)	COVESA_Towards vehicle DATA specification_AMM_04.2024.pdf Towards a Vehicle DATA specification presented at the COVESA's AMM 2024 Gothenburg, Sweden. Technical details and documentation of the suggested changes.	Uncovering the current limitations of VSS. A proposal that combines the features of the multiple approaches that have been presented so far into one.
VSS modeling language evolution	Daniel Alvarez	Presented during an open discussion with the technical steering team and VSS contributors on 28 Mar 2025 .	Evolve the VSS modeling language by doing one of the following: Replace the VSPEC modeling language (custom YAML) by a well-established language (e.g., GraphQL SDL), or Further extend the current language but commit more resources or capacity for the development of the tools
