I am a programmer with the Perseus Digital Library at Tufts University. We are
in the process of rebuilding our site's catalog based on MODS records. We are
particularly interested in FRBR because the nature of our materials is already
extremely hierarchical. In particular, we deal with multiple editions and
translations of works (like "The Iliad"), as well as commentaries, lexicons and
other secondary materials that relate to works. The collection is not very
large, and it is reasonably well organized: we already know which records are
expressions of which works, and we even have standard, authorized IDs for each
work (based on the Thesaurus Linguae Grecae and related projects).
What I have not been able to find in the literature is how to represent the
relation between an expression and a work in MODS. Would there be a record for
the work "The Iliad" as well as records for a Greek edition and a particular
English translation? Would the record for an English translation have two
<identifier> elements, one for the expression's ID and one for the work's ID? Is
there a standard way of declaring which is which? Would a given work be more
like an authorized uniform title, with a MADS record?
Thank you, and sorry if I have missed anything obvious!
