[Talk-GB] TfL Cycling Infrastructure Database

[Tony Shield]

Hi

Looking at the demo I can't think of a reason why OSM would not want 
this data - I believe we do want this data.

Questions I have -

  * Are the tags suitable for a global database? Can and should they be
    reused elsewhere in UK? or globally? Is there a need for specific
    prefixed TfL tags?
  * Are there clashes with other cycling data in London?  What is a
    resolution strategy?
  * Will import and integration be performed by automatic processing?
    Usual OSM import rules? Clash detection and sanity checking?

Regards
