NROSH - National Register of Social Housing
Data Structures & NROSH XML Schema

The detailed XML schema described at the ODPM site defines the XML data structures and field definitions. However these data standards and XML schema are complicated to for non technical users such as housing managers and surveyors.

So rather than struggle with the technicalities of XML you will benefit from using software systems specifically designed for NROSH. You should also be looking for toolkit integrators that can process new survey data along with existing data held in other disparate systems and out dated housing management systems.
