as_of

The state of one document as it stood on one date. Pure lookup, no ranking. mode=outline lists provisions without text and may be narrowed with anchors; mode=select returns only the named anchors' tex…

timeline

Every publisher state a document has been in: timeline intervals, version keys, and explicit timeline_semantics. Legilux intervals describe applicability; EUR-Lex intervals describe official consolida…

in_force_on

Compatibility name for publisher states covering a date, computed from timeline intervals and deduplicated by work. Legilux states describe applicability; EUR-Lex states are official consolidated word…
