When I test a query using SPARQL CONSTRUCT and then copy/paste the query to
make it part of a sh:SPARQLRule it usually works just fine.
However, if I use an escaped left or right square bracket as part of the
REGEX pattern, the CONSTRUCT portion of the SHACL SPARQL rule needs to be
edited.
Example: Use pattern to find something like "[4"
SPARQL:
VALUES ?find_pattern {'\\[[0-9]'}
SPARQL Rule:
VALUES ?find_pattern {'\\\\[[0-9]'}
If I use the SPARQL version of the pattern, EDG flags an error when the
rule is executed:
Lexical error at line39, column 27. Encountered: "[" (91), after "\'\\"
I believe this has something to do with [ needing to be escaped for REGEX
and then the \ in \[ needing to be escaped for Java.
Would it make sense for EDG to automatically convert \\[ to \\\\[ when
encountered in an instance sh:SPARQLRule?
Thanks,
Clare
