Re: Machine-readable cardinalities

I've released a tool that extracts cardinality of Schema.org's properties.
It is available on GitHub: https://github.com/dunglas/php-schema.org-model
The result file containing extracted cardinalities is attached.

The tool extract the cardinality from Good Relations if available or try to
guess it using some regular expressions (
https://github.com/dunglas/php-schema.org-model/blob/master/src/SchemaOrgModel/CardinalityExtractor.php#L101
).

Schema.org has a total of 710 properties. The tool is able to extract
cardinality for 613 of them. For 197, the tool is not able to guess the
cardinality: the cardinality must be edited manually or the extractor must
be enhanced to support most sentences.

 If there is any plan to add the cardinality to properties in a
machine-readable format (like in Good Relations), we can complete and
double-check the generated cardinality.json file and automatically update
the labels of all properties in the HTML+RDFa file to add the cardinality.
