Child routes are taken from ASEU’s canonical route registry. Indexing status remains route-specific.
Line engraving
Line-focused engraving terminology preserved from source metadata.
Etching
Etched plate process explicitly identified by source metadata or BHL editorial research.
Hand coloring / watercolour
Watercolour applied to a printed plate; modeled separately from the underlying print process.
Lithography
Lithographic printing identified in authoritative contextual evidence.
Woodcut
Relief printing from a wood block, added from explicitly identified institutional source metadata in ASEU011.
Stipple engraving
Stippled intaglio engraving, kept distinct where Rijksmuseum explicitly identifies the physical process.
Trust boundary
What this page does not invent.
ASEU keeps historical claims, current scientific reconciliation, rights status, creator roles, provenance, image descent and editorial interpretation separate when the sources require them to stay separate.
R000067 is a parent integration, not a new ASEU research stage. It materializes the current canonical route and parent-participation contracts without declaring ASEU040 complete or expanding the source corpus.
