Browser 0.0 Berkeley Digital Library Project Multivalent documents is a new model of digital documents. This implementation is still available on for use on our scanned image document collection. MVD 0.0 should work on any reasonable Java-compliant web client. Also available are brief technical descriptions of layer data formats .
Some features are available for all documents in our scanned page collection.
Others features require additional markup and are found only on a subset. The multivalent document paradigm stands in contrast to the conventional monolithic document structures. Such documents generally are composed in a single mark-up language or document representation that is intended to anticipate all possible contents an author may wish to express. Such a specification is complex, and interaction with such a document is provided via concomitantly complicated viewers, generally of limited extensibility. In contrast, the multivalent approach presumes that a single document comprises multiple layers of different but intimately related material.
