Make SHACL regex patterns follow JSON Schema ones
Browse files Browse the repository at this point in the history 
We included the regex pattern as-is from the input which caused problems
with the regex engines as the patterns in the meta-model are written in
a Python dialect (and assuming that the regex engine works on UTF-32
characters). However, most regex engines in the wild operating on SHACL
(*e.g.*, Java SHACL validators) use UTF-16 to represent the text and do
not support some parts of the Python regex dialect. For example, in
the input meta-model specification, we omit the minimum bound 0
(*e.g.*, ``{,4}``), which breaks with the Java regex engine beneath
the SHACL validator.

Instead, with this patch, we parse the pattern from the specification
and re-render it into the form that we also use in JSON Schema. We pick
JSON Schema regex dialect as most SHACL validators in the wild can deal
with it, in particular those based on Java as a platform. Hence, we
decide to serve this user base with priority.

Discovered in [aas-core-meta issue 342].
