...the DfT — in conjunction with those who already use or will be making extensive use of the data — has conducted a thorough review of the original NaPTAN database standard (and other related standards). This resulted in the agreed development of a more robust version of the NaPTAN standard. NaPTAN v2 is the new standard. It has already been implemented on the national NaPTAN database, using data imported from local databases still operating to the v1 standard, as the start of the national migration to the v2 standard.
A further email letter about the migration was sent in April 2006, asking authorities to confirm which software they intent to use to maintain NaPTAN2 data.
The techical documents relating to the version 2 standard are on the Kizoom website.
They list the benefits of NaPTAN2 as being:
There then needs to follow a process of adjusting the content of the reorganised fields to meet the standards. This can be a lot of work and no deadline has been set for the data to comply. Once a region has converted to upload NaPTAN2 format feeds, users will not necessarily be able to depend on the content of the new fields meeting the NaPTAN2 standards.
Authorities should consider with their relevant regional traveline data manager whether the supplied software would be helpful to them, or whether there is a regional preference for an alternative and equally competent source of software for this purpose. Any alternative will be a matter for each authority to acquire from its own resources, but it is essential that whatever software is used provides complete implementation of NaPTAN v2 standard and a wide range of logical data checks over and above those which the XML schema can impose. A list of the checks that any alternative software should make can be made available on request from December 2005.
The NaPTAN data available to download from the National site is in NaPTAN2 format with an option to continue to download NaPTAN1. The conversion from one to the other is carried out by Thales whatever version is submitted, though not all the fields in NaPTAN2 will be populated if NaPTAN1 data is submitted. CSV and XML formats downloads will continue to be available for NaPTAN1 and NaPTAN2 formats.
If you choose to take the TransoniQ software, it will come populated with the last upload of your data as converted to NaPTAN2 by Thales, including the character changes referred to in the DfT guidance, and also some additional processing by TransoniQ to fit your place names into the new fields. You may wish to find out more details of any changes made to ensure that your data will continue to meet all your requirements.
Throughout 2006, you will continue to be able to upload data in NaPTAN1 format from your existing system, and you will be able to get an update of your TransoniQ system when you are ready to switch over to it for submitting your regular updates in NaPTAN2 format.
You should plan your migration in conjunction with your regional data manager to ensure that there are no consequences for the use of NaPTAN data within your regional systems.
DfT hope that all areas will migrate to NaPTAN2 as soon as possible and in any case before the end of 2006.
