Document Value Model: Value-oriented Programming for the Internet

Fritz Henglein, DIKU (Computer Science Dept, Univ of Copenhagen)

XML is all the rage.  How do we store and process XML documents,
however?  In this talk we present XML Value Store, a persistent
distributed (peer-to-peer) storage manager with a value-oriented
interface, the Document Value Model (DVM), for XML documents whose
parts may be distributed around the net and even moving around.  We
compare DVM with existing XML processing languages and specifically
the W3-consortiumbased Document Object Model (DOM).  We argue that,
apart from a series of technical advantages, the central benefit of
DVM is a simplified programming model that lets the programmer focus
on application logic, and the XML middleware on persistence
management, caching, replication, coalescing, encryption,
distribution, lookup, routing and internet data transport.
