tellico and SRU Servers as own data definition. (found a problem)

Sun Jun 24 07:26:59 UTC 2018

Ahoi! :-)
after digging through the sourcecode and working with the network
sniffer i identified following working search string:

http://services.dnb.de/sru/dnb?accessToken=TOKENNUMBER&operation=searchRetrieve&version=1.1&maximumRecords=25&recordSchema=MARC21-xml&query=%22Scheibenwelt%22

the recordscheme marcxml is not known at the dnb, it has to be
MARC21-xml, and at first i had problems with dc.title, too. but that
seems to work.
this only seemed to work, if i edit the config-file and entered there
the correct value.

at the moment i think, there could be a problem with the order of HTTP
parameters, but i have to verify that.

at the moment the search results only show one result, though more are
delivered. but i have to look into that.

its exciting to hack again! :D
