Prof. Arno Scharl of the MODUL University Vienna has send me an interesting Information about a project called Knowledge Planet. Unfortunately I had only litte time to look at this project, but it deals with with Ontologies and Knowledge Bases. Ontologies and Knowlegde Bases are populare buzzwords many people in the GI industy uses for neary everything, but in my opinion less people understand how this could applied properly to build up applications. I think this is one of the few implementations dealing with ontologies.
Excerpt of the mail:
At this year’s JavaOne conference in San Francisco, NASA developers showed that virtual globes are not only suited to explore geographic maps, but can also serve as rendering engines for other types of imagery.
The first public Knowledge Planet prototype, a java applet developed by a European team of researchers is now available (www.ecoresearch.net/climate). It visualizes large document collections using a landscape metaphor and was demonstrated by Tom Gaskins who leads the NASA World Wind engineering team at the JavaOne conference.
The peaks of the virtual landscape indicate abundant coverage on a particular topic, whereas valleys and oceans represent sparsely populated parts of the information space. The applet draws upon the extensive news archive of the Media Watch on Climate Change, which provides a continuously updated account of media coverage on climate change and related issues.
Further information about the Knowledge Planet, a screenshot and the underlying research project as well as the official press releases can be found at www.modul.ac.at/nmt/javaone .
Two-Day Google I/O Event in San Francisco Will Focus on Building Great Web Apps and Advancing the Web as a Platform
Google announced a new developer event for 2008: Google I/O™, a two-day, in-depth gathering for developers to share knowledge about Google’s own developer products and web application development in general. Google I/O will be held at the Moscone Center in San Francisco on Wednesday, May 28th, and Thursday, May 29th, 2008.
Google I/O will include a mix of practical, hands-on advice for building web apps as well as opportunities to learn about and discuss emerging trends. Sessions with top Google engineers will cover tools developed both inside and outside Google, including yet to be announced initiatives designed to move the web forward.
Five simultaneous topic areas will cover:
AJAX & JavaScript: AJAX and JavaScript continue to capture the imagination of web developers. These sessions focus on tools and techniques of client-side code, and how to use them to make serious applications quickly and easily.
APIs & Tools: Development tools for the web are evolving. Product APIs allow integration and extension of web applications. Tools like the Google Web Toolkit™ provide a whole new way to improve performance and compatibility.
Social: The web is an inherently social place. A new wave of APIs and frameworks, including OpenSocial, are opening up interesting ways to interact with people through applications.
Mobile: Mobile devices are blurring the lines between handset developers and web developers, opening up interesting opportunities for applications that span multiple platforms. We’ll take a look at how developers can use technologies such as Android™ and Mobile Gears to build applications on the mobile web.
Maps & Geo: Since the introduction of the Google Maps™ API in 2005, geo and map applications have been one of the most interesting phenomena on the web. These sessions focus on the many aspects of geo applications, from KML to the Google Maps API and more.
Tickets are $400 for developers, with discounts available for students.
Sessions related to Maps & Geo
Location, Location, Location (Android Engineers)
The ability to access, utilize, and display location information gives mobile applications a unique dimension. It’s also a feature built into the Android platform. Come find out how you can create applications that do the right thing, according to where they are.
From Mashups to Mapplets (David Day)
Mapplets are mini-applications that run within Google Maps, allowing you to add new features or overlay your data directly onto Google Maps. These applications allow a developer to take advantage of the power of the Maps API while getting exposure to millions of users on Google Maps. In addition, Google provides free hosting, free bandwidth, and an official directory where users from all around the world can find your Mapplet.
We’ll introduce Mapplets in detail, explain the benefits of writing one, and walk through the details of how to get started. This includes what you need to host your Mapplet and best practices for gaining users.
Participants should have knowledge of basic JavaScript and HTML. Knowledge of the Google Gadgets API is recommended, but not required. We’ll discuss how Mapplets relate to Gadgets in this session. Advanced Ruby Scripting for Google SketchUpGoogle Sketchup contains a Ruby API for users who want to extend the capabilities of SketchUp. The interface allows users to create macros, such as automated component generators and additional tools, to be included in the menus within SketchUp. This session will cover two Ruby technologies that can be used to add functionality to SketchUp: WebDialogs and Ruby Extension Modules. For those comfortable with web programming, WebDialogs allow you to create rich user interfaces easily. For those with a native library they’d like to use, Ruby Extension Modules can help with high performance computations.
Parsing and Generating KML with Google’s KML Library (Michael Ashbridge)
KML is a file format used to display geographic data in an earth browser, such as Google Earth, Google Maps and Google Maps for mobile. You can create KML files to pinpoint locations, add image overlays and expose rich data in new ways. This session will introduce Google’s open source KML library for working with KML files. We’ll explore its architecture and then show you how to parse and generate KML in your applications and scripts.
Advanced KML (Bent Hagemark)
This session will cover advanced techniques in KML for displaying data and creating dynamic presentations. We’ll show how to to use Region to display very large datasets without clutter and without compromising performance. We’ll also look at how time features can be used to add animation effects and how NetworkLinkControl and Update can be used to make dynamic KML presentations. (Participants should have a strong background in KML.)
Using Ads with Your Maps API Application (Jim Payne)
This session will explore strategies for using Google’s AdSense program with your Maps API application. We’ll discuss placement, targeting and how to choose the AdSense products that will work well with the Maps API. We’ll also review best practices for maximizing the value of your traffic. (Participants should have previous experience with the Google Maps API.)
Fireside Chat: Google Maps & Earth (Google Geo engineering team)
Fireside chats are a chance to talk to the engineering team building products. Come tell the team what you want, discuss issues and design decisions, and hear the team’s thoughts on just about whatever you ask.

This weekend the Barcamp SezaConfini will take place in Klagenfurt. Let’s see what we can learn form there. I’m looking forward to see some interesting talks. For more information check http://www.barcamp.at/BarCamp_Senza_Confini_2008
On this video you can see the most important highlights of the MacWorld 2008 Keynote.
This keynote didn’t contain any real big hits. The highlight was the Macbook Air, which was not really new. Eyeryone expected this thin subnotebook from apple. A little bit disappointing was that there was no traditionally “There is one more thing”. Also the stock market prize of Apple Inc. went down about 10% right after the Keynote.
There are a lot of speculations about the new products presented on the World MacExpo 2008. According to the motto “There are something in the air”, many websites predict a new subnotebook called Macbook Air. But I think we will see all details tomorrow 6 p.m european time, when Mr. Jobs starts his keynode. I hope it will be on YouTube soon, but I think it will be also possible to see it live on apple.com
