Scientific assets and revisions
An asset identifies a scientific object over time. A revision identifies an exact published state of that asset.
A curve needs its samples, missing-value mask, units and axis meaning. A map also needs sample positions and honest coordinate claims. Unknown coordinates must remain unknown.
Follow chooses the newest ready revision. Pin chooses a specific revision. Neither mode automatically reconstructs native application editing behavior.
Publication and authority
Section titled “Publication and authority”The intended OSDU contract makes a revision ready only when the exact metadata and payload are readable. Notifications are hints; reconciliation checks authoritative state after missed events.
One published asset has one authoritative backend. Changing backend is an explicit migration.
Derivation
Section titled “Derivation”A reproducible result records exact inputs, parameters, algorithm identity and output references. Full customer-facing History and Derived from experiences remain roadmap work.
