Barnard59 RDF Cube Operations

barnard59-cube is a JavaScript package offering a suite of operations and command-line interfaces for managing RDF cubes within Barnard59 Linked Data pipelines. It provides functionalities like `toObservation` for creating cube observations aligned with the Cube Schema specification and `buildCubeShape` for deriving SHACL shapes from observation streams. The package also includes robust CLI commands for fetching, validating, and checking RDF cube metadata and observations against defined constraints using SPARQL endpoints. Currently at version 1.4.10, this package is part of the actively developed `barnard59` monorepo, benefiting from continuous updates that incorporate dependency upgrades and minor feature enhancements. Its key differentiator is the seamless integration of RDF cube lifecycle management into stream-based data processing workflows.
