[OAI-implementers] How many records should typically be returned over OAI-PMH?

[Hussein Suleman]

hi Dan

i dont think there is a de facto standard ... but i recall some people a 
while back saying responses should not exceed about 1MB in size because 
of limitations of popular XML processing tools

if your responses are about that size and the RE does not accept them, 
let me know and ill increase the limits ...

ttfn,
----hussein

ps. personally, i think 500 records is fine
