I'm quite pleased with the simplicity of Xataface. Except for a couple minor bugs discovered with selection lists (doesn't allow using zero as an option value), had it up and running in a matter of minutes. The structure of the fields.ini and valuelists.ini optional files just plain makes sense:
# more cpu/fields.ini
[active]
widget:type = select
vocabulary = yesno
[oem_id]
widget:type = select
vocabulary = oem_id
[hyperthreading]
widget:type = select
vocabulary = yesno
#
# more cpu/valuelists.ini
[oem_id]
__sql__ = "select id,name from oem where active=1 order by name"
[yesno]
1 = "Yes"
2 = "No"
#
