  6. C# client for Allegrograph on github

  7. TopQuadrant releases version 3.1.1 of the TopBraid products

  8. Prerelease of RacerPro 2.0 now available

  9. Recorded Semantic Technology Webinars

1. AGWebView, view graphs with an ordinary browser

AGWebView gives you access to your AllegroGraph triple store data from a Web browser. Available for Windows, Linux, and Mac OSX.

For more information and to download

2. "Gruff" Training Videos - A Graph Browser for AllegroGraph

Gruff is a triple-store browser that displays visual graphs of subsets of a store's resources and their links. The current release is 1.4.1. There are now 8 short training videos.

Download Gruff and view the videos

3. AllegroGraph version 3.2 release, query optimizations & more

The primary emphasis on this version was optimizing query performance - on average, an order of magnitude faster. With this release, we've published new LUMB benchmark results comparing 3.2 to 3.1 on LUBM(50), and LUBM(8000) results.

The LUBM Benchmark results are here

Some of the other areas with performance improvements include RDFS++ Reasoning, get-triples, client/server bulk loading, SPARQL, Jena and Sesame.

For a complete list of new features and improvements

4. DBPedia Deutschland, using AllegroGraph, Gruff, and AGWebView

DBPedia Deutschland 1.0 Release - The German part of the Wikipedia for Machines runs on AllegroGraph. Humans can access the DBPedia data in the AllgegroGraph triple store using AGWebView from an ordinary Web browser. The first DBPedia Deutschland release and first use cases will be featured at the 3rd Berlin Semantic Web Meetup and CSW workshop at Xinnovations 2009, Berlin, September 15th.

Read the full press release

5. A Python Client now included with AllegroGraph RDFStore

This client is a full set of library calls for Python-based applications, and mimics the API defined for Sesame, using similar method names and argument conventions. However, we have also chosen to exploit Python features such as keyword arguments and iterator conventions that are absent in Java, resulting in a library with a genuine Python flavor.

Watch a recorded demonstration of the python client

6. C# client for Allegrograph on github

This free library fills the requirement for projects that need to be .NET compatible.

For more information and to download

7. TopQuadrant releases version 3.1.1 of the TopBraid products

There is an update to the document "Using TopBraid Composer with AllegroGraph". You can find the new document and a video demonstration of the new integration features on our TopBraid Composer page.

8. Prerelease of RacerPro 2.0 now available

RacerPro 2.0 integrates AllegroGraph as its persistent store and can now load OWL 2 ontologies from AllegroGraph, view them with Gruff, and perform reasoning. RacerPro inference results can be written back into AllegroGraph. There are many more enhancements and improvements.

For all of The details and to download the preview

9. Recorded Semantic Technology Webinars

Some recently added topics include:
- Geospatial Reasoning for Moving Objects
- Solving Scale and Reasoning in Large RDF Datasets
- Optimizing SPARQL for Diverse Ontologies
- Selecting the RIGHT Database for your Project (Relational vs. RDF Triple Store)

  2. AllegroGraph Version 3.0.1 Now Available!

  3. Pre-release of a Jena interface to AllegroGraph

  4. Free Webinar: GeoTemporal Reasoning in a Web 3.0 World

  5. Upcoming conferences

  6. Recorded Semantic Technologies Webinars


1. Gruff: A Grapher-Based Triple-Store Browser


Gruff is a triple-store browser that displays visual graphs of small subsets of a store's resources and their links, and can also display a table of all properties of a selected resource. By selecting particular resources and predicates, you can build a visual graph that displays a variety of the relationships in a triple-store. If you've watched any of the webinar series, you may have seen this tool in some of the demonstrations. There is a short, under 5 minute screencast introduction. You can watch the video and download Gruff from here.

2. AllegroGraph Version 3.0.1 Now Available!


We've released version 3.0.1 of AllegroGraph (the download instructions are below). New in 3.0.1 are improvements in SPARQL, free text indexing, the Social Network Analytics library, fixes for running AllegrGraphServer as a service on Windows, and performance improvements. Download AllegroGraph 3.0.1 from here.

Read the full change history here.

3. Pre-release of a Jena interface to AllegroGraph


A pre-release of a Jena interface to AllegroGraph 3.0.1 is now available. Two sample programs in the test package illustrate how the implementation classes are created. Once these are created, the application uses Jena calls that are documented elsewhere. Get the Jena API here.

4. Free Webinar: GeoTemporal Reasoning in a Web 3.0 World


Thursday, August 28: 10:00 - 11:00 am Pacific (as presented at GeoWeb 2008 in July)

Enterprises have begun utilizing semantic technologies and standards for knowledge representation, knowledge access and discovery. Combining this with GeoTemporal and Social Networking analytics is the next stage of Business Intelligence in the Enterprise. We will be conducting this talk and demonstration at the GeoWeb 2008 conference, this seminar will be repeat of the conference presentation for those that couldn't attend.

Reserve your Webinar seat now here.

5. Upcoming conferences


- GeoWeb 2008 (GeoWeb) Vancouver, BC, Canada - July 21-25. The talk is on "GeoTemporal Reasoning in a Web 3.0 World".

- IEEE International Conference on Semantic Computing (ICSC) Santa Clara, CA - August 4-7. We will be conduction the following tutorial, "Utilizing Federated Knowledge in Semantic Web Applications".
