Microsoft puts Some Oompf into Microformats

Thu, 06 Nov 2008 11:21:00 -0500

Internet Explorer users have a new tool to make use of Microformats even easier. The tool is called Oomph: A Microformats Toolkit, which was released as test software. Once installed, this runs as an addon in Internet Explorer to recognize pages that contain contact information or event details marked up with Microformat code. Then a nice little microformat icon shows up and you can interact with the data to save contacts to your address book or put events on your calendar.

Read more about the new tool in a blog post Microsoft and Microformats from John Allsopp, who literally wrote the book on microformats.

Here are some pictures:

You can already take advantage of microformats, even without creating them yourself. For instance, you might find events in Yahoo! Upcoming and add them directly to your calendar. Or you can search Google Maps or Yahoo! Maps and add them to your phone. There's a strange limitation to Yahoo! and Google address mark-up however. They don't include phone numbers or zip codes. I think this is by design and not a mistake. It's still pretty useful though.

Firefox users should still rely on the Operator Addon. Operator recognizes more microformats than Oomph, and there are more debugging tools for developers.

hCalendar Microformat: Better Than vCal?

There is much hype written about the semantic web, which is supposed to add context to content online, aiding computers and humans in better understanding information presented online. One area where it's fairly easy to add content and context is by using microformats. This is a way to mark up information online so other applications can recognize events, contact details or reviews. The mark-up is in the form of a common set of class codes that do nothing to change visual display, but can be read by computer programs recognizing this format.

We recently created a faculty events system for tracking on campus workshops and conferences. For all events, we create a vCalendar file (used with a .vcs file extension) for import to programs like Microsoft Outlook and Entourage. The problem is that Firefox and Internet Explorer handle .vcs files differently, forcing some users to first download the calendar file, then import it to another application. Also, .vcs files are not easy to import to services like Google Calendar.

Thankfully, we mark up all events with the hCalendar microformat, which contains all event details, even some not visible on the screen. The easiest way to take advantage of this markup is to use the Operator Toolbar, which is a Firefox extension. This recognizes the hCalendar format, and lets visitors save items directly to Outlook, Google Calendar, Yahoo Calendar and other places. The picture here shows the Operator toolbar in action.

Jesse Rodgers, a web developer at the University of Waterloo has written about How can Microformats help Higher Education, pointing out that and their university has an events system that has all events marked up with microformats. It looks like they have decided to forego creating downloadable calendar files (e.g. vCal or iCal) altogether. Read Rodgers' research paper on microformats in higher education for a literature review on the topic, as well as a model for implementing microformats.

Never met a data scheme we didn't like

On the Georgetown Law Library website, we have a collection of research guides ranging from Accounting Research to Wyoming Resources. As noted in an earlier post, we've enhanced these guides by adding links to related resources.

Now we are also adding metadata to the guides, in the form of Dublin Core. This is descriptive information embedded in each guide used to uniformly describe its contents. This may help with search engine optimization, but we're mostly doing this to help researchers find and cite our materials. To view the metadata, you can install the Dublin Core Viewer, a handy Firefox extension. Here's a view of the embedded data for one of our guides using this viewer.

Also, you can take advantage of this metadata automatically if you use a program called Zotero to collect and manage your research citations. Zotero allows you to capture information directly from web pages to store in a local research database. By using Dublin Core metadata on our guides, Zotero recognizes this and provides a way to directly store citations to our guides in their database.

In the near future, we hope to add metadata to include abstracts for our guides, as well as usage information. If there are other ways we can help enhance the guides, please let us know.
