OPML The OPML specification defines an outline as a hierarchical, ordered list of arbitrary elements. The specification is fairly open which makes it suitable for many types of list data. Support for OPML is available in Mozilla Thunderbird and many other RSS reader web sites and applications, can both import and export OPML files of subscriptions. XML format[edit] The XML elements in an OPML document are: This is the root element. Contains the content of the outline. Represents a line in the outline. Shortcomings[edit] The RFC 822 date format is considered obsolete, and amongst other things permits the representation of years as two digits. Validation[edit] Dave Winer has made a request for comments on a proposal for validating OPML and released a beta OPML validator. Katy Ginger from DLESE has published an XML Schema Document for validating OPML 2.0. Example OPML documents[edit] Alternative specifications[edit] See also[edit] References[edit] External links[edit]
Open Knowledge Foundation Harvard and MIT Release Visualization Tools for Trove of MOOC Data – Wired Campus - Blogs One of the visualization tools shows Harvard U.’s MOOC enrollment by country. (Harvard U.) Harvard University and the Massachusetts Institute of Technology have released a set of open-source visualization tools for working with a rich trove of data from more than a million people registered for 17 of the two institutions’ massive open online courses, which are offered through their edX platform. The tools let users see and work with “near real-time” information about course registrants—minus personally identifying details—from 193 countries. A Harvard news release says the tools “showcase the potential promise” of data generated by MOOCs. The aggregated data sets that the tools use can be also downloaded. The suite of tools, named Insights, was created by Sergiy Nesterko, a research fellow in HarvardX, the university’s instructional-technology office, and Daniel Seaton, a postdoctoral research fellow at MIT’s Office of Digital Learning.
