Pin Jena to 5.6.0 (arq 6.x breaks quad CONSTRUCT)#16
Merged
Conversation
arq 6.x cannot output quad CONSTRUCT results ("No dataset writer for
Turtle_pretty", exit 2; --results=trig was dropped), which the graphify
stage depends on — see apache/jena#4091.
- etl/config.mk: default JENA_HOME → apache-jena-5.6.0, with a comment
explaining the constraint.
- CLAUDE.md: document the Jena 5.6.0 prerequisite and the arq bug.
- datasets/current/taxonomies/{legal-forms,legal-statuses}.trig:
ETL regeneration under Jena 5.6.0 — reordering only, no semantic
change (round-trips identically via riot --output=nquads | sort).

Summary
Pins the ETL pipeline to Apache Jena 5.6.0. arq 6.x cannot output quad
CONSTRUCTresults (No dataset writer for Turtle_pretty, exit 2; the--results=trigoption was dropped), which the graphify stage relies on— see apache/jena#4091.
