rdf-canon skillA

rdf-canon is agent-read markdown (skill) from sparq-org/sparq: Canonicalize an RDF dataset with RDFC-1.0 (the W3C RDF Dataset Canonicalization, the URDNA2015 successor) using the opt-in sparq-canon crate — turn a set of oxrdf quads (or one graph's triples) into a deterministic, blank-node-relabelled canonical N-Quads string, or get just the canonical blank-node issuer map. Use when you need to hash, sign, diff, deduplicate, or content-address an RDF dataset, or to test two graphs for RDF-isomorphism (identical canonical form). Native + wasm; does not touch .

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add sparq-org/sparq/rdf-canon@git:20260903.1a63aa7
Exact content
mdr add sparq-org/sparq/rdf-canon@sha256:d750e2165f85926e

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
