OS MasterMap layer schemas
XML schema files and DTDs which define the contents and structure of OS MasterMap XML files. These are applicable for our longer-established layers; Topography and Imagery.
Version 9 – Current schemas
The version 9 schemas incorporate:
- Additional descriptive terms for OS MasterMap Topography Layer as well as a schema upgrade.
- English is removed as the default language, recognising that in many cases the name of a place is ‘accepted’, and may actually be, for example, Welsh.
- A change to the way chunkingPolicy and chunkSize are defined within the OSQueryResult.xsd, to satisfy contemporary XML validation.
