In their own words
AllegroGraph
AllegroGraph is a semantic graph database for building knowledge graphs and integrating complex data. It combines graph data with vector storage, symbolic reasoning and large language model integration. GraphTalker accepts natural-language questions about knowledge graphs and returns verified answers through an iterative, agent-driven process. Supported technologies include RDF, OWL, SPARQL, SHACL and Prolog rules, alongside reasoning. FedShard provides horizontal sharding and federation, combining query results from multiple machines. Analytics include geospatial, temporal and social-network analysis. Listed integrations include Solr, MongoDB and REST-based clients for Java, Python, RDF4J, Apache Jena and Lisp. The Free edition costs nothing and is limited to up to 5 million triples. Enterprise has no listed price and specifies unlimited triples with no server limit. AllegroGraph is available as a download or through cloud hosting, including AWS Marketplace and Azure Marketplace. The server runs natively on Linux x86-64; Windows or macOS use is recommended through a Linux virtual machine or Docker container.
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.
