1 Visit <strong>the</strong> SWOOP <strong>Web</strong> site at http://www.mindswap.org/2004/SWOOP to<br />

obtain <strong>the</strong> latest information on <strong>the</strong> tool, to download a free copy <strong>of</strong> <strong>the</strong> source<br />

code or binary release, and/or to try out <strong>the</strong> online demo.<br />

2 A URI is a generalization <strong>of</strong> <strong>the</strong> more common URL, roughly composed <strong>of</strong> a<br />

naming scheme or protocol indicator (http, ftp, mailto, etc.) a unique indicator<br />

(a domain space name for http, a mail address for mailto) and a “fragment id”<br />

which is a hash mark followed by a set <strong>of</strong> characters — thus, for example, an owl<br />

class called “person” from an ontology on a University server might be named<br />

by <strong>the</strong> URI http://www.thisuniversity.edu/OntologyLib/csontology#person.<br />

3 Bookmarks are ano<strong>the</strong>r example <strong>of</strong> hidden URIs, at least in <strong>the</strong>ir most common<br />

form. Browsers typically have many ways to review bookmarked URIs.<br />

4 We plan to extend our ontology evolution/versioning framework based on<br />

related work such as Stojanovic, Maedche, Motik, and Stojanovic (2002) in<br />

a specific project or working set. This practice is highly beneficial in understanding<br />

and debugging code.<br />
