68        Loom browses RDF as hyperstructure
69        ==================================
70    
71        We want to allow the users to bring together any information
72        items they decide related, no matter which task the
73        information originates from. These connections build a
74        hyperstructure, which should be easy to edit and navigate.
75        Formerly, we used Ted Nelson's zzStructure as the form to this
76        structure, but our current browser utilises the RDF standard.
77    
78        Currently, we apply our previous experiences to the RDF browser
79        called Loom. After 4 weeks of development, it can already
80        browse structures and soon also edit. RDF does not have the
81        limits of zzStructure, but we have learned from Gzz how to
82        visualize rich structures.
83    
84        RDF is a standard of the World Wide Web Consortium for machine-
85        processable information, and the Semantic Web builds on it.
86        Several other projects are using or evaluating RDF for
87        hypertextual information as well. Others can use Loom for
88        browsing, and we can make good use of the existing RDF
89        libraries.
90    
91    ..  zzStructure, but there are several alternatives. We re-evaluated
92        some other structures after Ted Nelson received a patent on
93        zzStructure and wanted to enforce it, and found RDF better for
94        us.
