METS Navigator is a Java application that displays and navigates multi-page digital objects using METS. It renders HTML and assumes discovery happens elsewhere. The technologies used include Java Struts, Castor Java & XML data binding libraries, Ant, and it runs under a Web application server. METS Navigator uses the <fileSec>, <structMap TYPE="physical">, and <structMap TYPE="logical"> sections of METS to organize files by size and function, provide sequential paging of documents, and drive table of contents navigation respectively.
