[Isis-users] MARC file import

[Piet De Keyser]

Renate,

Of course Ernesto's answer is, as always, correct - as he is the expert on CISIS. For non techis an easy way to convert such a MARC file is simply to import it into ISISMARC.

Renate

There are three features to note when importing/exporting marc files with Cisis or Winisis, etc using ISO 2709 standard

  1.  length of the line, wich in Isis is 80 chars (default) but you can modify it using 0 or marc
     *   including the end of line control, Isis uses two chars (LF+CR) by default or only one char in .mrc files
  2.  subfield deliminter, which is  ^  in Isis, but in marc it is a non representable ascii char (below 32)  \asc 29 in .mrc
  3.  leader bytes transfered in the first 20 bytes of the ISO file, and is not accesible neither in Winisis or Pft

Items 2 and 3 are implemented in Winisis, but item 3 is a feature only of CISIS

Therefore when you want to get the three items you have to do it using MX command,
I'd recommed to use 1660 version or MX, because it gets all the leader bytes

Let's say you want to import a .mrc file, from Library of Congress or Gutenberg project,


mx iso=marc=source.mrc  isotag1=3000  gizmo=gizdelim  create=myisisdb  now -all tell=100

  1.  iso=marc=source.mrc   is the source data, usually standard marc files comes with extension .mrc
  2.  isotag1=3000       you need this parameter so you move leader bytes into conventional field v30xx
  3.  gizmo=gizdelim    this is a gizmo to convert the delimiter \asc32 into our loved ^ as delimiter

If you don't have this gizmo  you can create it with the following instruction

mx null count=1 "proc='a1/1F/a11/hex/a2/^/'" create=gizdelim

Hi,

I want to import the catalogue of Project Gutenberg. It is available as a MARC file. I used the following mx command to convert is to isis.
mx iso=marc=gutenberg.iso create=dbn now -all

It seems to work ok, but when looking at the data, I notice that the ^ is not converted to isis format. It just shows

245  14    aTitle  h[electronic resource]  bStatement of responsibility

I see there are options for the import of the MARC file, but I do not know how to use them to get the ^ before the subfield.

Please help me with the correct format.
Thanks
Renate
