HTTP Protocol for Barnard59 Linked Data Pipelines

barnard59-http provides a set of HTTP protocol operations (such as GET, POST, PUT, DELETE) that function as 'steps' within Barnard59 Linked Data pipelines. Barnard59 is an Extract, Transform, Load (ETL) toolkit primarily designed for working with RDF and Linked Data, where pipelines are declaratively defined using RDF graphs (e.g., in Turtle or JSON-LD format) and executed by the `barnard59` CLI or programmatic API. This package extends the core Barnard59 functionality, enabling pipelines to interact with external HTTP resources. The current stable version is 2.1.0, and it is part of an actively maintained monorepo, with frequent patch and minor releases across its constituent packages. Key differentiators include its deep integration with RDF/Linked Data principles, its streaming architecture for handling large datasets, and the flexibility to embed custom JavaScript logic directly into RDF-defined pipelines.
