Create, parse, validate, and transform DataBook documents — Markdown files that function simultaneously as human-readable documents, typed data containers, and self-describing semantic artifacts. Use this skill whenever the user mentions DataBooks, .databook.md files, wants to wrap RDF/SPARQL/ SHACL data in a structured document, needs to generate YAML metadata for semantic data, wants to extract fenced data blocks from a DataBook, needs to build a DataBook pipeline manifest, transformer library, or processor registry, or asks about the DataBook spec at https://github.com/kurtcagle/databook. Also trigger for requests to produce a "semantic document", "knowledge artifact", or "self-describing data file" in the context of RDF, SHACL, or holonic graph work.
