hi We are finishing to convert an old database and we are currently trying to fill the marc table. I am currently having problem with two fields of the marc_word table: tagorder subfieldorder I have the idea that the two fields contain the number of the field and subfield entered when adding a biblio/item. The tagnumber tells if the tag is the first asked , or the second, and so on, in the form. The subfield number indicates if the field is the first field or the second (and so on) of the tag. For example, if i need to enter five fields to add a biblio : (215a,215b,400a,801a,995f, for example) each field will have a tag number, from 1 to 4 (1,1,2,3,4), and a subfield number, respectively 1,2,1,1,1. I hope you will understand, it is not that easy to explain ! :) My question is : do Koha need those fields (for researches or something else ) , or can i leave them empty ? Thanks in advance Michel LERENARD
