Hi to all, I report the developing of a metasearch in Koha Opac. a)The path that I try on Marsiglia meeting, to reuse the z39.50 interface of intranet, was a dead end. It is too slow, It download the records, insert them ino resevoir then display. b)Now I try to use pazpar2 with less modificaton on Koha as possible. c)So I create a new opac template and opac cgi d)I create a syspref to display a link to metasearch in opac header e)I doing also pazpar setup on command line. In fact it in not very difficult using this example: https://github.com/ssp/pazpar2-all f)You nee to insert a specific config in koha-httpd.conf Now I'm working on opac template and I have same problems with js (pazpar2 is called by ajax). I plan to release code with a big wiki page on installation for Koha 3.22 Bye Zeno Tajoli -- Dr. Zeno Tajoli Servizi Innovativi -- Automazione Biblioteche z.tajoli@cineca.it fax +39 02 2135520 CINECA - Sede operativa di Segrate
