NaPTAN
Downloads & schema
To use the NaPTAN or NPTG schemas in your applications, you may either reference the appropriate URL for a particular version of the schema, or use a local copy of the schema files and directories for that version held on your own machine. This page provides the information you need to reference or download different versions of the schemas. Further information on the substructure of the schemas is given in the NaPTAN Schema Guide.
- Please note that if you use the XML Spy tool from Altova GmbH to view downloaded schemas off-line, then if your computer is not connected to the internet you may see an error message at load time indicating that the referenced subschema xml.xsd schema cannot be found. The subschema xml.xsd contains the lang attribute. The message is shown even though xml.xsd is present in the download directory structure and referenced by a catalog. The error is an artefact arising from shortcomings in XML Spy's current implementation of W3C catalog standards, and may be ignored. Other tools such as parsers and validators should work correctly. Known issues with XML SPY are summarised in the TransXChange Technical FAQ
- Users of XML SPY 2005 are recommended to obtain SP2 (Feb 2005) or later which fixes a number of serious errors in the validator. Known issues with XML SPY 2005 are summarised in the TransXChange Technical FAQ.
Note that NaPTAN uses a systematic versioning scheme in line with e-Gif standards.
