Semantic Web technologies (in particular RDF, a graph-structured data format) are ideally suited for publishing data. Also, these technologies facilitate the integration of separate pieces of information; integration is what you want to do if thousands of people start publishing structured data. Linked Data (RDF using HTTP URIs to identify things) is already used by the NYT and the UK government to publish data online.

Yes, the better the data the better the system will work. However, VisiNav works quite well on relatively scruffy web data due to the integrated ranking component.
The underlying data has to be in graph-structured format (in RDF syntax); reasoning, most notably object consolidation, is supported via OWL. Once the data is indexed, users can search and browse right away. There's no configuration needed, because the ordering of data is done based on the calculated ranks. The UI can be configured via XSLT and CSS for adding a logo or changing the look and feel.
We've developed VisiNav as part of a research project, and the university owns (and manages) the IP. I guess they will make it available free of charge for educational and research organisations, but commercial applications would require a license.

Hi, there's also VisiNav which lets you assemble complex queries over data, covering keyword search and faceted browsing (as Flamenco) and a bit more (path navigation). Drag and drop UI, where people who don't know facets or path navigation can do keyword search without being distracted. -- Andreas. Disclaimer: I'm one of the developers of VisiNav.

There's the Future Internet Symposium 2009 (http://www.fis2009.org/ ) in Berlin next week which exactly targets the topic in the post. From the call for papers: "With over a billion users today's Internet is arguably the most successful human artifact ever created. The Internet's physical infrastructure, software, and content now play an integral part of the lives of everyone on the planet, whether they interact with it directly or not. Now nearing its fifth decade, the Internet has shown remarkable resilience and flexibility in the face of ever increasing numbers of users, data volume, and changing usage patterns, but faces growing challenges in meetings the needs of our knowledge society. Yet, Internet access moves increasingly from fixed to mobile, the trend towards mobile usage is undeniable and predictions are that by 2014 about 2 billion users will access the Internet via mobile broadband services. This adds a further layer of complexity to the already immense challenges."

In this case "free" means free as in you can do whatever you want with it (provided you have the right tools to do it) and not "free" as in free of charge.

Does that mean that people should not be developing GPL-licensed software for iPhone (as it violates the spirit of GPL, according to what you wrote above)?

It is free as in freedom - you can do whatever you want with it. You may want to compile an app, but nowhere does it say that the tools to compile the app (or the environment where you can run the app) are necessarily free. For example, there are GPL-licensed Windows programs but that does not mean you get Windows to run them in for free.

The Web is a medium. A URL is an address of some data on it.

The field has come a long way since 2001 or 2003.

The main obstacle to "this golden future" so far has been an insufficient amount of data published online. Many organisations sit on their data like hens sit on their eggs, and publishing data right requires some effort.

That's slowly changing, especially with more openness and transparency -- voluntarily or forced -- in all kinds of organisations and agencies (data.un.org, data.gov, data.gov.uk... ), more people getting the idea of open data, and the establishing of simplified best practices on how to publish data on the web following the Linked Data paradigm.

It's about time that Yahoo and Google finally start to take note and add open data to their systems (which don't exploit the full power of these technologies but hey you've got to start somewhere).

I use VIM (and MacVIM when on Mac), mostly for Python development. What's this "IDE" thing again?

-

I am wondering, though, what do others use for coding (and for Python coding in particular). Text editors are fine for many tasks, but perhaps there are more complex projects with lots of files which require something like Eclipse, etc. What's your experience w. that?

What if the software did not include the keys itself but provided an option to pull them from a known location on the internet (or maybe from torrents using a magnet link)?
