Copenhagen Programming Language Seminar
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 (such as on a cell phone
at 140 km/h on a motorway). We compare DVM with existing XML processing
languages and specifically the W3-consortium based 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. We finally
sketch a simple extension of XML Value Store with remote
execution. Together with storing code in the XML Value Store this lets
users send queries to remote XML Value Store for execution and promises
highly scalable grid computing functionality with a simple,
problem-oriented programming model.
