rdf_write tool, which parses and normalises the data or returns parse errors with line info. - Multiple Output Formats: Save graphs as .ttl (Turtle), .jsonld (JSON-LD), .nt (N-Triples), or .nq (N-Quads), with an optional format override. - SHACL Conformance Loop: Automatically discover applicable shapes with discover_shapes_for_class and validate with rdf_validate, iterating until the data conforms. - Use Case: Generate a FOAF-based knowledge graph describing people and organisations, write it as a normalised .ttl file, and confirm it passes all SHACL constraints in the workspace. ## Quick Start Create an RDF ontology file in Turtle format describing a Person class and save it as ontology.ttl, then validate it against any SHACL shapes in the workspace.High-intent search queries and answers about installing and using this skill.
Compose valid Turtle with declared prefixes and call the rdf_write tool with the Turtle text and target path. The tool validates, normalises, and writes the file, or returns a parse error with line information to fix.
Four formats are supported based on file extension: .ttl writes normalised Turtle, .jsonld writes compacted JSON-LD, .nt writes N-Triples, and .nq writes N-Quads. Use the format parameter to override the extension default.
Use rdf_patch when adding, removing, or replacing a few triples in an existing .ttl file, since it applies a SPARQL Update statement and rewrites only changed triples. Use rdf_write for creating new files or complete overwrites.
After writing, call discover_shapes_for_class for each type IRI to find matching shapes, then pass those shapes files to rdf_validate. If violations appear, fix the data, rewrite, and repeat until the file conforms.
The most common parse error is a missing final period at the end of a triple block. Also check that all prefixes are declared and that semicolons and commas are used correctly for grouping triples.
