3. Background
Major modernisation in ONS to automate data production processes wherever possible, reducing human intervention.
Need for a robust, controlled publishing process to minimise errors and improve efficiency.
Need to minimise technical skills required for publishing to the Internet.

4. Technology Base Data & Metadata Handling using:
J2EE Environment
Oracle 9i Database
Oracle Application Server
Publishing to Internet using:
Tridion Dialogserver V.5.0 Content Management System (CMS)
Result:
Major challenge to integrate data handling facilities with the CMS

5. Why XML?
XML mandated as integrating mechanism for UK Government Organisations
XML has been extended by a range of associated technologies:
XPath is a language for addressing parts of an XML document
Extensible Style sheet Language Transformation (XSLT) is a language for transforming XML documents into other types of document
Scalable Vector Graphics (SVG) is a language for describing two-dimensional graphics in XML. SVG drawings can be interactive and dynamic.
Using XML as a basis for dissemination adds to the overall system coherence

6. XSLT
Produces consistent output from XML files based upon a common schema.
XML File 1
XML File 2

7. SVG XML – based graphical display Good detail retention when zooming
Interactive
