openregs fetch-expression

Capture one sibling language Expression of a Work already in canon.

An EU act is equally authentic in every official language, so each language is a sibling Expression of one Work. Ingestion normalizes one of them eagerly and registers the rest in each unit’s meta.yaml; this captures one of those registered siblings on demand, normalizes it and writes it into canon beside the Expression that registered it. The URI comes from the registration, so a language nobody registered is refused rather than guessed at.

openregs fetch-expression [-h] [--offline-fixtures] [--regime <name>] [--config <path>]
                                 [--state-dir <path>] [--canon <path>] [--lock <path>]
                                 <work> <lang>

Argument
<work>	Work IRI, for example /akn/eu/act/reg/2024/1 (required)
<lang>	ISO 639 code of the wanted Expression, for example fra (required)

Option
--offline-fixtures	serve the registered URI out of the checkout instead of the network
--regime <name>	look in this regime’s canon only (default: every regime)
--config <path>	read this source configuration instead of config/sources.yaml
--state-dir <path>	keep the snapshot store and fetch state here instead of state/
--canon <path>	read and write this canon directory instead of regimes/<regime>/canon/
--lock <path>	append the provenance entry to this ledger instead of regimes/<regime>/SOURCES.lock
