In their own words
Apache Jena Fuseki
Apache Jena Fuseki is a SPARQL server that can run independently or as part of an application. It provides SPARQL 1.1 query and update protocols and the SPARQL Graph Store protocol. Fuseki integrates with TDB for transactional persistent storage and includes Jena text query. It can run as a standalone server, an operating-system service, an embedded component, or a web application in Apache Tomcat or Jetty. The project offers a plain server without a UI, and distributions include a ZIP with server and UI, Maven artifacts, and a WAR file. A project kit can build Docker or Docker Compose containers; databases need mounted volumes to survive container removal. The web application uses Apache Shiro, with access control at server, dataset, endpoint, and graph levels. Graph-level controls currently apply only to read-only datasets. By default, administrative functions are limited to localhost, while SPARQL endpoints are open. Fuseki is free, self-hosted software under Apache License 2.0.
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.
