Features

Querying

The ldfu system includes a streaming query engine for conjunctive queries (Basic Graph Pattern queries) over RDF data.

Data Access

The ldfu system supports high-frequency data access and manipulation via HTTP CRUD methods (Linked Data and Linked Data Platform). Request rules specify how to access data and traverse links. High-frequency access is suitable for Internet of Things scenarios.

Reasoning

The ldfu system provides functionality for large-scale data integration, including reasoning with ontologies. Deduction rules specify how to derive new data from existing data. Reasoning supports the integration of data from multiple sources.
