  1. Schema Translation – OS Mastermap, but not as we know it Eddie Curtis, Snowflake Software, Greg Byrom, Richie Fyall GeoData Management Group Ordnance Survey 22nd September 2005

  2. Schema Translation – project objectives Objectives of the Schema Translation project were: • Prove the concept of schema translation using OS MasterMap as the source • Investigate technical feasibility & constraints of using XML translation software for this purpose • Understand implications of presenting Ordnance Survey data using different target schemas • Understanding implications for internal Ordnance Survey data management

  3. Target schemas chosen • EuroRoads would be first choice, but no schema available. • KML: Keyhole Markup Language for Google Earth. (Not GML) • Simple Features GML: • We created a simplified GML schema for both topographic and transport/routing data. • GOS-TP (Geospatial One Stop - Transportation Pilot): Transport network schema. • OKSTRA: Transport network schema for German road network.

  4. Translating OS Mastermap GML

  5. ITN to OKSTRA translation

  6. Conclusions To do schema translation: • Understanding of XML schemas is a necessity. Ability to analyse target schemas and decide which fields to match. • Schema documentation is a necessity. OS Mastermap schema very well documented, others vary. • Many XML schemas are still in research or development phases, especially market sector specific schemas. • Only semantically similar XML schemas can be used as target schemas. • Schema Translation is a flexible, useful tool for Ordnance Survey to produce data tailored to market requirements.
