_______________________________________________________
It would be nice to extend logical fields to support generic functions that
given the MARC of a record returns a list of strings.
These logical derived fields would be available at indexing time, searching
time and formatting time (e.g. via a bfe_derived_logical_field).
They could be based on a plugin structure (as in BibFormat), with a
well-defined API. E.g. the function could accept the record object, and
return a list of tuple (derived string, relative MARC field if appropriate or
None otherwise, if the relative MARC field exists the string could be thought
as a subfield).
E.g. suppose that you have 123__ $a SURNAME $b NAME. Then a function can
take the above MARC and return:
[("SURNAME, N.", 123__ $a SURNAME $b NAME), ...]
BibIndex/WebSearch can just care about the string part, while BibFormat could
exploit also the knowledge about the relative field (if appropriate), to
create e.g. sensible HTML links with smart text.
