[Koha] Data Migration from "Alice for Windows" to "Koha"

[Mark Tompsett]

Greetings,

I don't know, but here is my guess.

Those two file formats (.dat or .rtf) probably could be renamed as .mrc or 
.mrk.

If you open those files in wordpad and see something like:
--- BEGIN SNIPPET ---
=020  \\$a971-508-125-8
=100  1\$aVirgilio S. Almario$eauthor
=245  10$aIbong Adarna
=260  \\$c1980
=300  \\$a32
=386  \\$b73$cPhp
=500  \\$aThree princes went on a journey to catch the elusive and 
enchanting Adarna bird, to cure the sickness of their father, the King. One 
of the best known Filipino folk stories, Ibong Adarna is filled with 
adventure and magic.
=500  \\$aTatlong prinsipe ang naglakbay upang hulihin ang mailap at 
kabigha-bighaning ibong Adarna, upang malunasan ang karamdaman ng kanilang 
amang hari. Isa sa mga kilalang kuwentong-bayan sa Filipino, ang kuwento ng 
Ibong Adarna ay puno ng abentura at mahika.
=521  0\$a9+
=546  \\$aFilipino (Tagalog) with English translation
=700  1\$aJordan Santos$eillustrator
--- END SNIPPET ---
Then it is a .mrk file

If you open those files in wordpad and see something like:
--- BEGIN SNIPPET ---
00582nam  2200157 a 45000010007000000050017000070080041000240940015[CUT OFF 
INTENTIONALLY]
--- END SNIPPET ---
This it is a .mrc file

You could then use MarcEdit (http://marcedit.reeset.net/downloads) to clean 
up your data and make sure you have a .mrc file.

You will need =952 fields to import nicely into Koha. I think 
http://bywatersolutions.com/2014/10/17/preparing-records-koha-import/ does a 
great job of describing some steps you likely need to do.

Hope this helps.

GPML,
