We call their RDF equivalents RxPath, RxSLT, and RxUpdate respectively. http://rx4rdf.sourceforge.net RDF Transformation Racoon is a simple application server that uses an RDF model for its data store, roughly analogous to RDF as Apache Cocoon is to XML. http://rx4rdf.liminalzone.org/Racoon Application Server Rhizome is a simple content management and delivery system that is similar to a Wiki except that you can author arbitrary XML and RDF metadata and the structure of the website is stored as RDF. http://rx4rdf.liminalzone.org/Rhizome Easy RDF Query Language (eRQL) is an intuitive, easy to use query language for RDF based upon RQL http://www.dbis.informatik.uni-frankfurt.de/~tolle/RDF/eRQL/index.html RDF Query an editing tool for RDF contents http://mmm.semanticweb.org/mr3/ RDF Editor a diagram-based ontology editor for OWL implemented as a Protege plugin http://iweb.etri.re.kr/ezowl/ Ontology Editor an Eclipse plugin for browsing information within the Universal Information Service Browser http://www.rdfx.org RDF Browser free Topic Map browser and RDF converter http://www.ontopia.net/download/freedownload.html Topic Map Browser RDF query language inspired by XPath http://uche.ogbuji.net/tech/rdf/versa/ RDF Query http://www.schemaweb.info/parser/Parser.aspx RDF Parser a simple and elegant utility to browse OWL ontologies in a hyperlinked thesaurus-style format http://www.mindswap.org/~aditkal/swoop.shtml OWL Browser a highly configurable text editor based on the UNIX vi editor http://www.vim.org Text Editor provides menu-accessible functions for autogenerating common OWL constructs http://projects.semwebcentral.org/projects/owlvim/ OWL Editor a database monitor-type application featuring a zoomable user interface http://rdqlplus.sourceforge.net/ a Validating Parser, Editor, and Web Development Environment for XML, RDF, and OWL http://www.web-iq.com/xmlrdfdownload.htm a declarative mapping language for treating non-RDF databases as virtual RDF graphs within the Jena toolkit http://www.wiwiss.fu-berlin.de/suhl/bizer/d2rq/ RDBMS Mapping an OWL-DL reasoner using a first order theorem prover, with support for SWRL http://owl.man.ac.uk/hoolet/ Inference Engine custom JSP tags and functions for using Semantic Web ontologies (RDF/OWL) in JSP pages http://semweb.krasu.ru/SemWebsite/
