Talk:TOID

Wikipedia previously had information about the semantic content of the TOID itself, in the Ordnance Survey article. This seemed wrong so I removed it. It read:

Every feature is given a unique topographical identifier or "toid", which also includes information about its type. For example, the height of a low bridge is encoded into its toid.

The error possibly came from the Guardian article. In support of my change, I quote the OS:

It would be possible to make the TOID intelligent; for example, it could be made up of the National Grid coordinates of each feature. However, this would impact on the strength of an identifier that stays the same throughout a feature's life cycle. (OS: TOID FAQs)
Every OS MasterMap feature has a unique identifier known as a TOID. This is a number that uniquely identifies that feature. TOIDs hold no intelligence; they are allocated sequentially as updates are applied to the database. The TOID will stay the same throughout the life of a feature. (OS MasterMap user guide)


I was just visiting the page and found the link "OS: TOID FAQs" http://www.ordnancesurvey.co.uk/oswebsite/products/osmastermap/faq/toidfaq.html is no longer working.
