dotNetRDF

dotNetRDF is a free and open-source library for working with RDF (Resource Description Framework) data within the .NET ecosystem. It provides a comprehensive set of tools and APIs for parsing, manipulating, querying, and serializing RDF graphs. The library supports a wide range of RDF syntaxes, including RDF/XML, Turtle, N-Triples, and JSON-LD.

Developers can use dotNetRDF to read RDF data from various sources, such as files, URLs, or databases, and then represent it in memory using a powerful graph object model. This model allows for efficient traversal and modification of RDF triples. The library also offers robust support for SPARQL, the standard query language for RDF, enabling users to retrieve specific information from their graphs.

Key features of dotNetRDF include its extensibility, allowing for custom parsers and serializers, and its integration capabilities with other .NET technologies. It is designed to be both performant and flexible, catering to a variety of applications that require semantic web data processing. Examples of its use include building semantic web applications, data integration, knowledge graph management, and natural language processing. The project is actively maintained and benefits from community contributions.
