[Dspace-general] custom submission

[instituto A.C.Jobim]

Hi this is my first post to the list
I am going to use DSpace in the Instituto Antonio Carlos Jobim, a great 
brasilian composer, my father.
We have catalogers working in our archives for about two years. They 
are using a simple database with Marc tags on the many many fields they 
use. It is not a real working MARC but follows their cataloging view. I 
have made a first import to dspace just for testing in my powerbook 
computer (Mac OS X). we already have some authority tables for relating 
persons, works(most music) and in the future recordings(Masters) of the 
songs.
I am planning to import these tables to tables similar to "dcvalue" so 
I can have my relations directly with postgresql accessing teh dspace 
tables. (I read somewhere that MIT is already adressing this issue).
I have tried to customise the jsp of the submission for our use in the 
Institute. the first change would be in the authors field where we 
would like to qualify the authors with their different roles (composer, 
lyricist, arranger, etc). I managed to introduce these new fields in 
the edit window after finishing submission, but not during the first 
stage of submission. It looks like it would be necessary to modify the 
submit servlet, what I would not like to do for future compatibility 
but I think MIT could change it in a way that any qualifier added to an 
element could be accessed by a pulldown menu, the same way we can do 
with the identifiers. I read in the list that a way to customise the 
submissions are being developed. I am looking foward to see it. I hope 
this post can be usefull
