...Which is why
you, Ray, volunteered to nail down the attributes for DC indexes.

Ok, here's a start.  Please check the suggested mappings below for dc title word and string and if this seems to be the right approach I'll draft the remaining ones.

     DC Title

   1.dc.titleWord
        may map to either of the following combinations:
            a) attribute set: bib-1  -- use 1097,  structure: 2
            b) attribute set xd --  access point  1;    attribute set utility --
                expansion/interpretation 1, expansion/interpretation 3,
                comparison 3
2.dc.titleString
        may map to either of the following combinations:
            a) attribute set: bib-1  use: 1097  structure: 108
            b) attribute set xd --  access point: 1;    attribute set utility --
                comparison 3
 

I'll leave the remaining indexes for later, after I get comments on these two.
