In their own words
Protégé
Protégé is a free ontology editor for building and managing ontologies, offered as Protégé Desktop and the browser-based WebProtégé. Both editions support OWL 2 and are described as cross-compatible. WebProtégé supports collaborative viewing and editing, with sharing, permissions, threaded discussions, watches, email notifications, and revision history. Ontologies can be uploaded and downloaded in formats including RDF/XML, Turtle, OWL/XML, and OBO. Protégé Desktop connects directly to description logic reasoners such as HermiT and Pellet. It can keep multiple ontologies in one workspace and provides structure visualization, inference explanations, and refactoring operations. Desktop is written in Java and can be extended with plug-ins. The project provides documentation including FAQs, tutorials, user guides, and developer documentation. Free support is available through mailing lists monitored by team members and experienced community users; users must subscribe before posting. The project says researchers, organisations, and governments worldwide use Protégé. Desktop is community maintained, with Damien Goutte-Gattat identified as its current primary maintainer.
RDFox
RDFox is a main-memory data store for centralized RDF graphs, queried with SPARQL 1.1. It represents rules and ontological axioms with Datalog, OWL 2 and SWRL, and updates rule consequences as data changes; it can process 2–3 million new-fact inferences per second. Its supported knowledge-graph technologies include RDF, SPARQL 1.1, Datalog, SWRL, OWL 2 RL and SHACL. Java applications can connect through a native API, or RDFox can run as a standalone server through a REST API. Import and export formats include CSV, JSON, N-Triples, Turtle, TriG and OWL 2 Functional-Style Syntax. It can replicate knowledge and data changes across servers to maintain service during an outage, and deployments are described for cloud, on-premises, on-device and edge use. RDFox runs on Linux, macOS and Windows. Security features include encryption at rest, mutual-TLS client-certificate authentication and OpenID Connect single sign-on. Pricing is on request; the free 30-day evaluation license is restricted to evaluation and non-commercial use.
