||The architecture that supports the presentation of MOA2
Objects in the Library at UCB has five main Components:
MOA2 XML Objects. These are XML documents that have been encoded
according to the MOA2.DTD standard. Each MOA2 XML Object represents a digital
entity such as a digitized book, diary, photoalbum, etc.
MOA2 XML Repository. This repository on disk contains the MOA2 XML
MOA2 Java Objects. Before it can be used, each MOA2 XML Object must
be converted to an MOA2 Java Object. The MOA2 Java Object contains the
same information as the source MOA2 XML Object from which it derives. But
this information is arranged in a format optimized for queries and navigation
requests issued by the MOA2 Servlet.
