We've been studing the Koha Database Schema (for release 2.2). According to this document we find out that one biblio is shared by many biblioitems, as many as copies of the book we have. In order to load the database how do I represent this reality in MARC 21 records?

you mean biblio and items I think. If you really mean biblioitems, then you're wrong : 1 biblio means 1 biblioitem line. But may be many items.

You're right I mixed up in the schema, I'm not used to the notation used in this schema.

One idea we have is building a full MARC21 record for each copy of a title we have. If this is the way of doing things the Bulk marc import should take into acount this situation and make one biblio and as many biblioitems as copies of the book we have.

no, 1 biblio & X items.

Now is understood.

The other idea is Build a full record with as many 035 tags as copies of that book we have. Again bulkmarcimport should take into account this and build the biblio and biblioitems needed.

We want to know what is the proper way to build our records in order to get this reality fully represented in the koha database.

Yes, that's the proper way if you speak of biblio & items. in this case, the 035 subfields MUST be mapped to item tab (10) and don't map a 035 subfield in another tab (except for ignore).

Ok, we'll continue working towards this direction. Andres
