[Koha] MARC TODO list

[Tonnesen Steve]

I've generated a short TODO list for adding MARC support to Koha below.
I've also checked most of my files into CVS now.  I've placed most of them
in the koha/marc/ subdirectory, but the koha/C4/Catalogue.pm file is also
required to convert existing koha records to marc format.

Please do not use any of this on production systems yet!



TODO list

1.  Finish cataloguing api (Catalogue.pm)

2.  Modify existing code to use the new cataloguing api
  a. start with all write routines
  b. then all read routines

3.  Polish up MARC editor.  Must include some sanity checks to prevent
    modifications with the MARC editor rendering the data unusable by
    Koha.  
  a. don't delete the barcode, warning before modifying barcode
  b. don't mess up linkages between 852 and 876 tags
  c. Home branch and holding branch info should require warnings before
     updating.
  d. others?

4.  Need to create some indexes of the MARC data to aid in searches.
    Soundex searches would be nice.
  a. subject index
  b. title index
  c. author index
  d. dewey index
  e. itemtype index
  f. soundex indexes would require an index with 1 word in each record.
     For example, a book with the title "The Habitat and Lifestyle of the
     Elephant" would have entries for "Habitat", "Lifestyle" and
     "Elephant" all pointing to the book's record.  An sql query like
     "select Record_ID from soundex_index where soundex(word) like
     soundex('elefant')" would return a point to "The Habitat and
     Lifestyle of the Elephant".  (Personally, I think this is pretty
     silly, but I had some librarians ask for it, and it isn't overly
     difficult to implement).  Soundex searches should be configurable as
     an option somewhere.  For example, have a special interface for young
     children where they just type in a word and hit enter and soundex
     searches are used, but normal searches do not use soundex.  It would
     be annoying for titles with the words 'Rode' and 'Road' to show up
     when you search for 'Rhode', for example. 

5.  A million other things, probably...
