Data and the Web

As a follow up to my previous post on e-government, just wanted to let those who are interested know that there's a free conference offered next week that will get much more in-depth about the initiatives for changing the way government uses and disburses information. The conference will also have a particular emphasis on using semantic technologies.

Here are the details:

From E-Gov to Connected Governance: the Role of Cloud Computing, Web 2.0 and Web 3.0 Semantic Technologies

Tuesday, February 17, 2009.

Morning session: 8:30 am EST to 12:00 noon. Afternoon session: 1:00 pm EST to 4:00 pm EST.

Synopsis: “We have a new administration that values transparency, citizen participation, collaboration, information sharing, and internet technology… The purpose of this conference is to operationalize this vision, demonstrate the kinds of changes that are coming to next stage web-based systems in government, and to map the role of information and communication technologies (specifically, cloud computing, Web 2.0, and Web 3.0 semantic technologies) in the evolution of government information systems from e-gov (silos with web front ends) to connected governance (e.g. distributed social computing environments for collaborative work, information sharing, knowledge management, and participatory decision-making.)”

Whenever I take the train in and out of Chicago, I'm reminded about how much better things would be if there was greater adoption of the Semantic Web. In order to find the train times, I have to navigate through the esoteric organization of the Chicago Metra train website– and every time, I'm struck by how much useful information is just sitting there, waiting to be set free with semantic markup.

The Metra site itself is easy enough to use, if you're already familiar with the train system in Chicago. However, it's got to be quite a challenge for anyone who's new to it.

The problem is that the train schedules are organized according to train lines, rather than by what station you're traveling to or from. For instance, when you click the “Quick Schedule” link, you just get a list of all the train lines in the system, with options like the “Metra Heritage Corridor Line” and “Metra BNSF Railway Line.” This works great if you know where these train lines run. Unfortunately, if all you know is that you want to get from Chicago to Elmhurst, well, you'll need to dig around quite a bit to figure out the correct train line to take.

This is where the Semantic Web could really help.

When the data on the Metra site gets marked up semantically, the information it offers will no longer be tied to the way it is presented on the page or limited to being organized and consumed in only one way. So, if the train schedules are given a universal resource identifiers (URI) and other semantic markup, they would be available directly to the rest of the web and could be accessed and used independently from the way they're organized in the Metra site. The data itself would be its own web-based resource.

As a result, Metra could continue to list their schedules according to each train line, if they think this is best methodology, but other users and applications would have the ability to re-use this information and present it differently. For instance, a person might be able to type in “Chicago” and “Elmhurst” into a trip planner on an iPhone and have it look up the train schedule automatically.

And this is obviously just one drop in an ocean of possibilities. As Tim Berners-Lee notes in his “Giant Global Graph” article:

“Now, people are making another mental move. There is realization now, ‘It's not the documents, it is the things they are about which are important'. Obvious, really.”

The web is mainly a set of connected documents right now. But, as the Semantic Web grows, an increasing number of data resources will have the ability to be connected to each other, with the potential for being re-mixed and re-purposed.

That will definitely be a good day. But until then, I suppose I'll just have to remember to take the Union Pacific West Line…

Update (01/05/2009): Looks like Google is trying to make this process easier with their Google Transit Feed Specification, although it appears that there is a bit of resistance out there from the transport agencies…
