I've been adding several coins to my collection in OmniCoin lately and ran into the fact that I have to repeat many similar things for each coin.
Would it be possible to create a system in which you can enter multiple coins more easily?
one way would be to create a form with several fields, organized like a table and that you can fill in and then post them all at the same time.
Another system could be: the member creates a comma separated values file with al required data in a specific sequence and loads that file into OmniCoin, which then processes the file.
each line is one coin and could look like:
United States, 2005, UNC, Ocean View Nickel "D", c:\pictures\D_obverse.jpg, c:\pictures\D_reverse.jpg
United States, 2005, UNC, Ocean View Nickel "P", c:\pictures\P_obverse.jpg, c:\pictures\P_reverse.jpg
etc. etc.
This would also apply for BanknoteBank.com obviously.
http://www.eurobilltracker.com uses both systems for users who have entered more than a certain amount of notes, and it makes it a lot easier and faster to enter notes.
