several things about external application sources

[Jérémy Frey]

Hello,

I'm trying to setup an external application source which fetch data from an 
online database. It works great, I managed to put 700+ books with it.

In order to improve the script, I have some questions :

- Will you add other values than "keywords" in the adding dialog ? I had to 
create different sources : one for looking for an author, the other for the 
title, etc. It would be better to be able to select the type of information 
we want, like for amazon. Another argument to add : %2 ?

- As I said, my script gets data from internet, and because of that it's 
sometimes slow to retrieve all informations. It would help me a lot if there 
was a way to add an entry in two steps. First tellico lists books 
fetched by the script ("fetch.py -author asimov") with few informations 
(author, title, year). Then,  when the user wants to add an entry, tellico 
run the script again (for example "fetch.py -author asimov -entry 12") and 
put in the database the new result (this time the script also gets cover 
image,  publisher, comments, etc.). The server which hosts the database 
will appreciate, I'm sure.

- Last but not least (in fact it's first on my wanted list) : update infos. 
Looking a little at the source code, I understood that you haven't yet 
implemented the update event for an external application. I haven't 
tested this new feature with other sources and I don't know how it actually 
works.  Send a command like "fetch.py -update [name of a field]" would be 
perfect : I put a link to the page of the database, like the amazon link. 
And like amazon, the link contains a unique ID.

Err...I think I finished. Except these details, tellico is now the software 
I've always dreamed to have in order to manage my books. Great job ! :-)
