Syntax of Abstract URIs

Any relative URI may be considered an abstract URI. In addition, URIs that begin with a set prefix may be considered abstract URIs. In the Archimedes project, we use the prefix http://archimedes/. For the Archimedes Project, the following are examples of abstract URIs:

• http://archimedes/036/01/001.jpg
• 036/01/001.jpg

These are not abstract URIs:

• http://mjschief.mpiwg-berlin.mpg.de/test.xml
• http://archimedes.fas.harvard.edu/036/01/001.jpg
