An implementation of HTTP-triggered Google Cloud Run Functions providing W3C Verifiable Credentials Issuer and Verifier endpoints.

A command-line utility for processing JSON-LD, RDF, RDFC, JCS, CBOR-LD, and multiformats with native executables for Ubuntu, macOS, and Windows - completely free of JVM dependencies.

Uniform API to read/write tree data models - cross-format, cross-library.

A JSON-LD 1.1 (JSON-based Serialization for Linked Data) Processor & API

Minimalistic RDF micro-interfaces to facilitate efficient and straightforward integration across Java RDF libraries

Semantic, self-describing binary format for Linked Data
