As <abbr title="Rich Site Syndication">RSS</abbr> becomes more and more prevalent as a way to publish and share information, it becomes increasingly important that location is described in an interoperable manner so that applications can <strong>request</strong>, <strong>aggregate</strong>, <strong>share</strong> and <strong>map</strong> geographically tagged feeds.</p> <p> To avoid the fragmentation of language that has occurred in RSS and other Web information encoding efforts, we have created this site to promote a relatively small number of encodings that meet the needs of a wide range of communities. By building these encodings on a common information model, we hope to promote interoperability and &quot;upwards-compatibility&quot; across encodings. </p> http://tags.library.upenn.edu/makerecord/url/2246 http://tags.library.upenn.edu/makerecord/url/2246 &quot;TagCloud is an automated Folksonomy tool. Essentially, TagCloud searches any number of RSS feeds you specify, extracts keywords from the content and lists them according to prevalence within the RSS feeds.&quot; http://tags.library.upenn.edu/makerecord/url/2126 http://tags.library.upenn.edu/makerecord/url/2126 Check this out.
