Hi, This email is to the Jena, Sesame, and Protégé mailing lists. I hope my attempt at efficiency works! I am trying to decide on an embedded Semantic Web engine for my Java application - an XML-RPC server for which I need a high performance storage and querying system for semantic web data / triple. I’d not only like to offer my initial perceptions of Jena, Sesame, and Protégé, but also learn from this dialogue to effectively differentiate the three Java tools from each other. I am, as a sole developer, having difficulty in this subject. Therefore, there must be many others. Please make me/us aware of any general comparisons available online or as published material. I found Protégé a very useful GUI, and generator of files. Sesame has adaptable server functionality, and seems to be quite adaptable on the backend through SAIL. Jena seems to be a focused and robust API. My needs are fairly focused but my implementation undefined because I am not sure what functionality is 100% ready. I am also unsure how to understand and label the layers of functionality I may need. Basically my needs are: store and retrieve large amounts of data in a many-user environment. do complex queries and inferencing embed via an easy to use API marshal query results into java objects my own application can work with (instead of URIs) Thanks for your time and efforts. Regards Jonathan Hendler PS: Since Java already has a good hold on web services, I feel that the Semantic Web is another opportunity for Java to mature into what is was meant to be – easy cross- platform development and deployment of applications. I feel that the documentation and quality of Jena, Sesame, and Protégé all meet my expectations but I want to be around for the stage where I can use them, and recommend them, for complete, individually produced, commercial software development efforts. I eventually plan to use this application commercially, but first for my nonprofit – http://www.equiforum.org . |

Sesame and Jena are, to some extend, quite comparable: both are toolkits for storing and querying RDF. The differences between the two are in things like inference support, performance and query languages. Protégé is quite different, I believe, in that it focuses on editing RDF data/ontologies. I haven't played a lot with Jena myself, so I do not have a comparison readily available. But if you find one, please share it with us. There are some Sesame-Jena related postings on this forum. Most notably: a Note and a Quesition Sesame/Jena, and Inference and different repositories
Sounds feasible with Sesame. Sesame has been tested with tens of millions of triples, offers the powerful SeRQL query language and features, since 1.1-RC1, the combined repository and Graph API for handling RDF programmatically. Just let me know if you any more detailed info. Arjohn ---------------------------------------- Arjohn Kampman, OpenRDF project lead, Aduna |

I just remembered that the SIMILE Store Report, which compares several RDF triple stores. Announcement can be found in the RDF-interest archives: http://lists.w3.org/Archives/Public/www-rdf-interest/2004Jul/0139.html. Follow-ups to this posting contain some valid criticism on the comparion. Arjohn ---------------------------------------- Arjohn Kampman, OpenRDF project lead, Aduna |

FYI: a parallel discussion on this subject can be found on the jena-dev mailing list. Original post can be found here. ---------------------------------------- Arjohn Kampman, OpenRDF project lead, Aduna |

For both links I get a page that says "This topic has been viewed 1877 times and has -1 replies" (of course viewed ... times is different between the two).  |

Hmm, that's weird. I'm afraid I don't know what happened to thes pages. Well, they're probably too old to be relevant anyway. Any specific info that you're looking for? ---------------------------------------- Arjohn Kampman, OpenRDF project lead, Aduna |
