The openGPS consortium [1] is presenting the first draft of the ISO 25178-72 at the TC213 meeting in Vienna on 5th and 6th February with the title

"Geometrical product specification (GPS) — Surface texture: Areal — Part 72: XML file format x3p"

X3p is yet based on ISO5436-2 which is not describing its implementation in xml. It is also missing some useful extensions already implemented in x3p. Therefore part 72 of ISO 25178 has been created covering all features of x3p.... read more

On the last ISO-meeting the TC213 decided that the X3P data format derived from ISO 5436-2 will get an own standard. It will become a member of the ISO 25178 family: Its new name will be ISO 25178-72.
