# XML Schemas

Keyfax uses XML based schemas for defining start-up data and the results returned from Keyfax. \
\
Although the start-up and export  schemas are completely configurable, standard templates have evolved to support both **Repair Diagnostics** and **Enquiries** scenarios. 

The schemas defined here are intended as a definitive guide to how to pass input data and translate output from Keyfax into Housing Management Systems, Tenant Portals or other calling host applications.\
\
These schemas should be used whilst testing Integration scenarios, and as a general starting point for new installations.
