# Metacrafter Registry

> Open registry of 1504 semantic datatypes and 308 patterns: identifiers, personal data (PII), codes and classifiers. Records have a description and, where known, a regular expression, examples, a check-digit algorithm, links to Wikidata and Schema.org, and the tools that detect them. Metacrafter uses these ids to label fields of tables and data files.

Every record has a `status`. Draft records have not been reviewed yet and may be incomplete or wrong; do not treat them as authoritative for legal or compliance decisions. Each record also has a quality score (0-100). Record pages have Markdown twins: append `.md` to any `/datatype/<id>` URL.
