RDle

RDle (Resource Description Language Editor) is an open-source software framework designed to create, edit, and validate graph-based data described in the Resource Description Language. It provides both a graphical user interface for visual editing and a programmable API for automation, validation, and transformation of knowledge graphs. The design emphasizes interoperability, extensibility, and ease of use for data engineers, researchers, and educators.

RDle consists of a core engine that handles graph storage and operations, a visual editor for constructing and editing nodes and edges, a validation module for enforcing constraints, and a data input/output subsystem that supports multiple serializations and sources. It is built to be extended via plugins, including additional data sources, exporters, and transformation tools. The scripting interfaces support popular languages used in data work.

Applications and usage: RDle is used in knowledge graph projects, data integration, semantic data modeling, and teaching concepts related to linked data. It supports workflows such as schema design, data cleaning, and graph querying. The project promotes open standards and interoperability with related technologies like SPARQL-inspired query interfaces and shape-based validation approaches.

History and reception: RDle originated in an academic setting and evolved into an open-source project with community contributions. It is regarded as a practical, lightweight option for teams seeking accessible graph editing tools, particularly for small to medium-scale projects and educational contexts.
