Straight translations from MARC to [anything else] don't make sense unless you analyze not just the MARC coding but the intention and meaning behind the data element. (I covered this is in a code4lib journal article, to some extent.[1]) That some bit of data was broken up in a certain way in MARC is not necessarily meaningful in other situations. Title is a good example, and Thomale shows how hard it is to make sense based on MARC subfields.[2] One other example is personal author: the x00 field has a dozen or more subfields to encoding personal author data. In other MARC fields, all of that information is placed in a single subfield (because of the limit of 26 data subfields per tag). *100 **$a*Hamilton, Milton W. $q(Milton Wheaton), $d1901-** *773* *****$a*Hamilton, Milton W. (Milton Wheaton), 1901-** Yet one of the biggest problems in translating MARC to [anything else] is that because the data has only been expressed as text strings, no consistency checking has been done on the content. That 245 $p could have anything at all in it, including Aunt Martha's apple pie recipe. Developing a future format based on this data is a formula for failure, I'm afraid. Yes, we will need to translate our old data to some new form, but that is not the same as developing a new format intended to mimic the data of old one. kc [1] http://journal.code4lib.org/articles/5468 "MARC21 as Data: A Start" [2] http://journal.code4lib.org/articles/3832 "Interpreting MARC: Where's the Bibliographic Data?"
