Thank you but I know this.
I create dictionaries by hand in open text format called
Lingvo DSL format and convert to html/opf using
open source Rubi script dsl2mobi. This script always creates valid html and opf files suitable for subsequent building machine-searchable dictionaries.
My upload is an html file created by dsl2mobi from short two-entry dsl file.
In works perfectly well with mobigen and kindlegen 2.9.
