A simple command-line utility designed to process JSON-LD, RDF, CBOR-LD, and multiformats documents.
Supports batch workflows, canonicalization, serialization, encoding, decoding, and format conversion for linked data resources, binary identifiers, and content addressing formats in knowledge graphs, decentralized identifiers (DIDs), and semantic web applications.
Built with GraalVM, ld-cli delivers native executables for Ubuntu, macOS, and Windows - eliminating JVM dependencies.
- W3C JSON-LD 1.1
- W3C CBOR-LD 1.0
- W3C Standard RDF Dataset Canonicalization Algorithm
- RFC 8785 JSON Canonicalization Scheme (JCS)
- W3C CCG Multibase - Base-encoding format with self-describing prefixes
- Multicodec - Self-describing content type identifiers
- Multihash
