Hm, indeed, there's only a symlink for v2.0.


The symlinks should be created in d/rules:

execute_after_dh_install:
	find /usr/share/openapi-specification/schemas -name schema.json \
		| while read SCHEMA; \
		  do jq '.["id"]' $${SCHEMA} | tr -d '"' \
			| perl -pe 's/#?\n$$//' | md5sum | cut -d ' ' -f 1 \
			| xargs -i ln -s $${SCHEMA} debian/libjson-validator-perl/usr/share/perl5/JSON/Validator/cache/{}; \


In pratice this does not end so well because:

# find /usr/share/openapi-specification/schemas -name schema.json
/usr/share/openapi-specification/schemas/v2.0/schema.json


v3.0 and v3.1 have a schema.yml:

# find /usr/share/openapi-specification/ -name schema.yaml
/usr/share/openapi-specification/schemas/v3.1/schema.yaml
/usr/share/openapi-specification/schemas/v3.0/schema.yaml


For v1.2 probably
/usr/share/openapi-specification/schemas/v1.2/apiDeclaration.json
is the closest thing …


Cc'ing Andrius, who also maintains the openapi-specification package.
