Models: Composites - structured components

• In hypermedia systems, composites can become arbitrarily complex.
• On the right are three composite components (nodes). The first has its multimedia object stored in an external but local file, while the other two have their multimedia object interally stored.
• The large composite on the left has a complex data structure, so one can come in with a key (e.g., a name in a directory) and then follow links to various other (possibly child) components.
