Hi Alexandre, What is the use case for adding geographic meta data to syslog messages? Why should this be an RFC?
Why would this not be payload (and therefore not part of any syslog standard)? Where would the data be sourced from, presumably a GPS attached to the device generating syslog messages? GPS typically output NMEA sentences, serialized as ASCII text. It might be easier computationally and standards-wise to adopt the appropriate NMEA sentence format, "GLL", and include that in the relevant syslog messages: http://www.gpsinformation.org/dale/nmea.htm#GLL. This solution would invalidate my next two comments. However GLL does not include altitude data so you would still have to account for that; currently GPS vendors use proprietary NMEA 0183 sentences for this purpose (there's information on the same page). The WGS 84 coordinate system referenced in the draft uses an X-Y-Z coordinate system, not latitude and longitude. You should explicitly call out that these are signed values and what valid sign characters are, etc., and not use "latitude" and "longitude". If you want to use latitude and longitude, the messages are missing cardinal compass direction references (N/S and E/W). Also altitude is presumably signed in this case. I hope this is helpful.
