  "classes_note": "Two classes, each sourced from the field by locus, and kept apart because the address names one object and the record another: (1) the removal of embedded metadata in sharing and transit, which is what the tests measure (B13, B12, B4, B9); (2) embedded image metadata as a provenance carrier, which is what the tests test (B12, B2; the census's provenance_carrier). The census's own lineage and kind for the entity are 'media' and 'test series' (census.json rows[slug == 'iptc-photo-metadata-tests'], lineage, kind); neither is a string the archive uses of other things, so they are not run as classes. Aliases: the operator's abbreviation and full name (a string candidate on 'IPTC' bears on the operator or the standard and is admitted at D only where the tests are named; a claim the archive makes on the standard is read at O-class 2, the carrier, and composed as a claim on the carrier, never as a claim on the tests), the Working Group and the tests' page names, the Embedded Metadata Manifesto the User Guide endorses, the IPTC's Metawatch (the census's successor in method) and GetPMD, and the domain. Admission by reading (§3.4): a sentence or paragraph that makes a claim on the tests, on embedded metadata's survival in transit, or applies an archive category (provenance erasure, PER, scaffold, Layer 1 metadata, survival) to either class; a bibliography line, a checklist or a field map of the archive's own files is not a claim on the class.",
