[Koha] Some questions about mapping data between Koha and MARC

[Andres Tarallo]

Well I've finally imported some records into my Koha system.

Now I'm working with the mapping from my imported ITEMS (MARC) to the 
Koha database.We find that in the items TAB there're a lot if fields 
that can be mapped but don't have a mapping.We want to know what are the 
following fields intended for:

** *datelastseen : This field is managed by the circulation module?

**** datelastborrowed: Same question
 
**** renewals:

**** reserves:
*
** location: What is this intended for?
*
We've been wondering what's happens with the price and replacementprice, 
in which currency are they held?, our library has books that are 
purchased in our local currency (pesos uruguayos) and many that are 
imported (payed in dollars or euros). For us is very important to keep 
both the currency also, I think that this situation maybe common to 
other latin american libraries.

Thanks

Andrés
