Evaluate whether ISO 20078 (Extended Vehicle / ExVe) is the right standard to reference when architecting a neutral-server connected-vehicle data access integration

Steps
Identify which of the four ISO 20078 parts is relevant: Part 1 (content and definitions of the Extended Vehicle concept), Part 2 (access/common communication protocol), Part 3 (security, including auth and delegation of access), and Part 4 (control — a Technical Report on registration and granting/denying/revoking access)
Confirm the Extended Vehicle (ExVe) model: the OEM operates a neutral backend server that exposes vehicle data/services via web APIs, so third parties integrate without needing direct in-vehicle hardware access
Cross-reference which OEM or regional body (e.g. ACEA-endorsed programs) actually implements ExVe-aligned APIs before assuming a given OEM's developer portal follows the standard literally
Map delegation-of-access and revocation flows described in Part 3/Part 4 to your own consent and token-revocation handling
Purchase or license the actual ISO document text for authoritative clause-level detail before building compliance claims on top of secondary summaries
Known gotchas
ISO 20078 is a paid standard — the full clause text isn't freely browsable, so treat public summaries (industry articles, position papers) as directionally correct but not a substitute for the licensed text
Part 1 was revised in 2021, superseding the original 2019 edition — make sure any cited clause numbers reference the current edition
'ExVe compliance' is a voluntary architectural pattern, not a certification an OEM API can be tested against — don't assume conformance just because an OEM markets a 'neutral server' data platform
