Scalability Report on Triple Store Applications

Abstract This report examines a set of open source triple store systems suitable for The SIMILE Project's browser-like applications. Measurements on performance within a common hardware, software, and dataset environment grant insight on which systems hold the most promise for acting as large, remote backing stores for SIMILE's future requirements. The SIMILE Project (Semantic Interoperability of Metadata In like and Unlike Environments) is a joint research project between the World Wide Web Consortium (W3C), Hewlett-Packard Labs (HP), the Massachusetts Institute of Technology / Computer Science and Artificial Intelligence Laboratory (MIT / CSAIL), and MIT Libraries.

Funding is provided by HP. Contents Introduction This report focuses on the performance of existing data store systems built specifically for the Semantic Web.

[protege-discussion] JENA vs SESAME vs PROTEGE: msg#00271 misc.o

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 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.

Thanks for your time and efforts. Regards Jonathan Hendler. OpenRDF.org - View Thread - Sesame vs Jena update evaluation. View Thread - Jena (SDB) vs. Sesame performance issue. Jena (SDB) vs. Sesame performance issue Hi All! It seems that this is my first post on this forum so I would like to welcome everybody here:) What bothers me is a comparison of performance between three triple stores engines: Jena, SDB and Sesame 2.1.

I've been doing a simple performance tests that consisted of two operations: 1) inserting a pool of about 70k random triplets. 2) randomly querying engine for them. However, after a few tests I'm getting strange results.. It is important for me because I am about to choose one of these engines as a triple-store that would store a huge amount of triplets... Sharendipitous Moments » Blog Archive » Moving to Flash, Part 2: We’ve started taking advantage of Facebook ’s special swf tag and now your Sharendipity creations will play directly inside your Facebook feeds when you post them! Now you can easily share custom apps that are unique to your friends and they can interact with them just like it’s a video.

No more new tabs or windows to launch the app elsewhere. These are the steps I followed to share an app with my wife to share my Christmas list. 1. Copy the URL of the app Copy the URL from your browser’s address bar for the application you’d like to share. 2. You can share your link directly on a friend’s page (if they are permitting it) or you can share it on your own wall. Alternatively, you can use the AddThis share options found on the asset page to post or email your application directly to Facebook. Once you’ve posted the application, anyone that finds it within the feed can play it directly. What custom app would you like to share with your friends? We’d like to help you extend your reach as well.
