Problem: HEP experiments (e.g., LHC) produce petabytes of raw collision events. Metadata about detector calibration, trigger configuration, and reconstruction algorithms is stored in separate condition databases. Often, condition databases are lost or version mismatches occur.
Metadata is useless if the history is a black box. Enforce a culture where developers must write meaningful check-in comments in the EME/ACE. ab initio metadata
A compact schema definition (e.g., Protobuf, JSON Schema, or a custom binary encoding) that includes: Problem: HEP experiments (e
