The format allows locations localised on one map to be found on another map to which the data have been transferred.[1]
OpenLR requires that the coordinates are specified in the WGS 84 format and that route links are given in metres. Also, all routes need to be assigned to a "functional road class".
The specification is licensed under a Creative Commons license.[2]
TomTom has published a library for the format under the GPLv2.[2]
