• name of project: unknown
• sponsor/requested by: Susanne
• class: literary resource catalog
• title: ?
• rights: ?
• original environment: supposed to be WIN95, but it seems as if it is plain vanilla MSDOS 6.x or lower. (yeah, let's talk about long term preservation right now!)

found at this excavation site:

1. one .EXE file plus a couple of binary files
2. *.DAT seem to carry the actual data, that is TIT.DAT and PERS.DAT
3. several other files named m/{TIT,PERS}\.[IE][0-9]/ which seem to carry some kind of index; these are not really relevant, as far as I can tell right now.

DAT File structure

• Files seem to be encoded in CP437

structuring elements

Code	Meaning
0xFF	seems to indicate a record separator
0x01	seems to indicate a sub-record separator
0x00	seems to indicate a field separator

statistics

code	TIT.DAT	PERS.DAT	Comment
0xFF	1	524	record separator?
0x01	3165	671	sub-record separator?
0x00	45000	6629	field separator?
0x0D 0x0A	3165	?	end-of-line/end-of-record?
0xDB			record filler?

TIT.DAT

starts with: 0xFF "000 620.005" 0x00 (that's 11 bytes)

PERS.DAT

starts with: 0xFF "000 1.100" 0x00

general notes

the DAT files data fields seem to be strings which are structred by the application, so this is outside of the scope of the perl module "DBF::Unknownw";

notes about the application level data ==

• seem like librarians have been at work here, each (sub-)records looks like this (first entry from PERS.DAT):

{
      'fields' => [
        '000 1',
        '100 Achleitner, Karl',
        '110 Karl (Carl) Kellnarn',
        '120 *30.10.1859 Braunau (O<99>)',
        '130 +17. 12. 1914 Senftenbach (O<99>)',
        '140 GG; Kosch 3; AK',
        '150 Lehrer'
      ],
}

• each field carries some three-digit numerical field code (MAB?), followed by the string representing it's content.
• 000 indicates the record number, "001" is it's value in the example above.

strange items

PERS.DAT

look at these items

• "000 114.100 Ehmann, Helene"
• "Bancalavi, Gustav"
