The class emphasizes RSS as a convenient alternative to more traditional methods of staying on top of professional literature and includes hands-on activities for participants to set up a feed reader, select and import individual feeds and OPML bundles, and view and edit feeds in a feed reader.
These widgets provide a clean, tabbed interface to access the current contents of top journals (selections being made from the core OPML bundles).
The only two aggregators that support reading lists at the time of this writing are OPML Editor (http://support.opml.org) and Blogbridge (http://www.blobridge.com).
Another OPML reader is Grazr (http://www.grazr.com), which allows users to add multiple Web-based OPML feeds.
OPML Editor (http://support.opml.org) is a top contender on my list.
We host your OPML files and provide you with personal URL links to your OPML.
Dave Winer, author of the OPML specification, explained that "OPML [is] an XML-based format that allows exchange of outline-structured information between applications running on different operating systems and environments" (http://www.opml.org/about).
As an XML format, OPML specifies a standardized set of metadata elements that describe outlines.
An OPML document consists of three parts: the <opml version=""> root element, a <head> that holds basic information about the document's history and display parameters, and a <body> that contains one or more <outline> elements.
OPML (Outline Processor Markup Language) is best defined as a list of feeds.
Most aggregators fall short in using OPML files since they only grab content when the user manually inputs the file.
If feeds were stale and deleted from the OPML file, they would also be cut automatically from the subscription list.
