RDFox is an in-memory knowledge graph engine designed to process a high volume of inferences. By operating in RAM rather than on disk, it is designed to reduce query and loading times for datasets containing billions of triples.
The software is intended for enterprise-level organizations, particularly in regulated sectors such as financial services, healthcare, and manufacturing. It allows users to define logical rules using Datalog or SWRL, which the engine applies to facts to derive new knowledge automatically.
Deployment options include cloud instances, on-premises servers, and on-device or edge installations for IoT and mobile applications. The system provides access via RESTful and Java APIs and supports standards such as SPARQL 1.1.
Buyers should confirm if they have the technical resources to manage a knowledge graph and whether their specific data formats are supported by the available import options.
Key Features
In-memory Processing
Runs data operations in RAM to support faster loading and query response times compared to disk-based systems.
Incremental Reasoning
Updates derived facts in real time as data is added, changed, or removed without requiring a full system restart.
Automated Materialization
Automatically calculates and stores the logical consequences of rules within the knowledge graph.
Semantic Reasoning Support
Supports industry standards including SPARQL 1.1, Datalog, SWRL, OWL 2 RL, and SHACL.
Flexible Deployment
Supports installation on cloud instances, on-premises servers, or edge devices such as Raspberry Pis and smartphones.
Explainability
Uses logic-based derivations, allowing users to trace how a specific conclusion was reached.
Use Cases
Regulatory Compliance
Supports the detection of patterns and the application of complex rules for financial crime or healthcare regulation.
Semantic Search and Recommendations
Supports the delivery of more accurate search results by using knowledge graphs to find precise information.
Product Configuration Management
Supports the management of compatible component permutations for manufacturers and retailers in real time.
Autonomous Vehicle Decision Systems
Designed for onboard devices to support immediate and explainable decision-making for autonomous systems.
Data Integration and Analysis
Supports the consolidation of large volumes of information to identify knowledge and relationships.

FAQ
What is RDFox used for?
- RDFox is used for semantic search, regulatory compliance, complex product configuration, and data integration using knowledge graph and reasoning technology.
Does RDFox support real-time updates?
- Yes, it uses incremental reasoning to update the database in real time as data is added, changed, or removed without requiring a restart.
Where can RDFox be deployed?
- It can be deployed on cloud instances, on-premises, or directly on-device and at the edge for IoT and mobile applications.
How is RDFox different from disk-based databases?
- RDFox is designed to run entirely in-memory, which may result in loading and query times that are faster than disk-based alternatives.
