Embedded fields of UNIMARC #11

Open isergey opened 13 years ago

isergey commented 13 years ago

Thank you for pymarc! But pymarc can't handle embedded fields in UNIMARC scheme. Eg:

EX 1 Embedded fields technique 200 1#$aKesteven chronicle ... 205 ##$aFosse Way ed. 430 #1$12001#$aLincolnshire chronicle$1205##$aNorth Kesteven ed.

Sorry this has sat open for a while. Do you happen to have a record I can test with?

Field 463 have subfield $1 with inner fields 001, 101, 200 etc (inner record). Lang of record - russian, encoding UTF-8. Record file https://github.com/isergey/marc/raw/master/record.mrc

edsu commented 12 years ago

Thanks for the record. pymarc seems to be able to read it. For example this works:

record = pymarc.reader.MARCReader(file("record.mrc")).next()

What specifically isn't working for you?

isergey commented 12 years ago

Yes, it's work, but now inner fields handling as plain text. In my patch, inner fields converts to Field instances. it is more easy for working with record , as it seems to me.

edsu commented 12 years ago

I'm still confused about what is broken. Can you supply a unit test?

anarchivist commented 12 years ago

I think I understand. UNIMARC allows for fields to be embedded in certain linking entry fields (4XXs), as expressed in the "1" subfields in some of the records above.

@isergey - @edsu is right; we would need a unit test for the code to make sure it's working and further changes don't break the rest of the module.
