[OAI-implementers] Questions from a novice

OAI is based on the HTTP protocol (i.e. the Web).

There are a number of implementations of the protocol that use Perl, but
there are also implementations in Java, PHP, C (I think). You should be able
to implement OAI in any programming language that is supported by a Web

In OAI 1.x, and 2.0, OAI requests are in the form of a URI (i.e. you can
type them into a web browser's location and they'll work). The Web server
responds with XML, just the same as it would normally respond with HTML to
human clients.

In ASP you should be able to change the header that the Web server sends
out, including the MIME type (which must be text/xml for OAI responses), or
change the status code in the event of an error. You will also need to make
sure you are producing XML in the UTF-8 encoding - there may be an option in
ASP to do this.

n.b. I would suggest waiting for OAI 2.0 (June 1st) before putting a lot of
effort into building a 1.1 OAI export.

All the best,
