Convert: DAB index

[chrisvire]

DAB can have multiple reversal indexes. The dictionary has a default or vernacular language which is the language being documented. There is also an analysis language, which is the language used to enter the notes, glosses, and definitions.

There is a reverse index of the glosses back to the head word in the dictionary. The data.sqlite database has an entries table that has id and name fields. The reversal index (which has the file name index-[langid].idx) has a list of glosses in a related language (often the analysis language) with the id from the entries table. It is a tab separated values file (TSV).

Here is the top of an example file:

abon ikan	1471
abu (sisa pembakaran)	1050
ada	2345
adat-istiadat	768
adu	604
aduh	0
advokat	16
