  24. 24. RSS is Important for Educational Designers. Just as news resources are indexed and distributed in the RSS network, so educational resources can be indexed and distributed in a learning object network. The model provided by RSS is very different from the model provided today by learning content management systems (LCMSs). In the world of the LCMS, everything is contained in one very large software application. Insofar as content is distributed at all, it is distributed in bundled content libraries. This means that educational institutions must make a major investment in software and expertise in order to access learning content. Stephen Downes about using RSS in education (Stephen’s Web, ) <ul><li>RSS, by contrast, is not centralized. It is distributed. </li></ul><ul><ul><li>Content is not distributed in bundles, it is distributed one item at a time. </li></ul></ul><ul><ul><li>There is no central store, repository or library of RSS content; it is all over the internet. </li></ul></ul><ul><ul><li>To access and use RSS content in a viewer or in a web page, you do not need a large software application. A simple RSS reader will do the trick. </li></ul></ul>
  25. 25. For this reason, many more people will use a distributed learning object network not only because it’s easier and cheaper, but because they can access much more content for much less money.
