Technology & standards
Study identifiers, access controls, interoperability, and the systems behind digital product records.
Design the information path
A practical architecture connects source systems, validation, identifiers, access, and presentation. Choose technical standards from current authoritative specifications and your actual interoperability needs.
Useful starting points
- Map source systems and integration boundaries.
- Test read and update permissions separately.
- Document data portability and long-term access.

How do identifiers link a battery, its model and its parts into one record?
An identity graph connects the model identifier, the individual battery identifier and component identifiers, so a scan reaches one battery without merging histories or splitting one battery across records.
How does a battery passport record stay available for the life of the battery?
Long term availability depends on identifier persistence, resolver continuity, format migration and operator succession planning, each tested before the original operator, domain or system disappears.
How is a battery passport system put together?
A passport system separates source records, the passport service, identifier resolution, access control and presentation, so each part can fail, change or move without breaking the others.
