Data gathered by CMX is stored locally in the database (see e.g. [[Dayfile.txt|dayfile]] and [[Standard_log_files|standard logfiles]] and a range of ini files, Extra Sensor files, Airlink logfiles etc...).

This chapter is about the | This chapter is about the [[Full list of Webtags]]. The names of the webtags are basically functional i.e. you can guess what the value says. The order of the tags in ''the local list'' is unknown, most likely it is a mix of time of origin, functionality and alphabetical ordering. The order of the tags in the full list is functional i.e. they are grouped by an arbitrary functional partition. Within such group no effort has been made to order according to another ordinal. | ||
