After uploading a kicad board file I can get this:
Maybe some of their supported EDA packages can include the MPN etc. fields. KiCad doesn’t have name/value fields in the footprint/board file format.
@AndersG, you should contact Aisler and ask them if they could add support for full projects (or board + schematic files), or if they could take a BOM file in a specific format.
KiCad has customizable BOM generator, they (or even some volunteer) could write a BOM generator which generates the needed file if one of the existing BOM generators doesn’t give output which they could read programmatically.
