Describe the package
List sources, file formats, date coverage, schemas, field meanings, units, encoding and known omissions. Include stable version identifiers and checksums where appropriate. Explain whether timestamps are original, normalized or transformed.
Describe relationships
Document join keys, relationship types and cardinality. Mark inferred links and explain their validation method. List how pseudonymous identities are represented without disclosing a re-identification key.
Document transformations
Explain deduplication, filtering, redaction and derived labels. Link quality findings to the exact release and reviewed scope. A manifest is most useful when a recipient can reproduce a check and see why a missing record is missing.
