Dear Colleagues, I would like to replace an old-fashioned library cataloging system with Koha 3.0, but I am not sure, weather Koha will suit my needs. My records are in UNIMARC format. The library uses a hierarchical structure of bibliographic records to store the information about series, issues of serials, content of cataloged books (i.e. for each article/chapter in the book an individual bibliographic record is created and field 463$0 was used to point upwards at the in bibliographic records of the issue/book; 461$0 was used to point from individual issues record to the record of a serial). Installing Koha (3.0 from git, w/Zebra, UNIMARC flavor), importing and indexing records went well (all records went to biblio/biblioitems/items tables), despite of suspicious entries in log file while importing and then querying the database: 23:15:32-23/07 zebrasrv(29) [warn] Index 'tpubdate' not found in attset(s) 23:15:32-23/07 zebrasrv(29) [warn] Index 'Modified-code' not found in attset(s) 23:15:32-23/07 zebrasrv(29) [warn] Index 'char-encoding' not found in attset(s) 23:15:32-23/07 zebrasrv(29) [warn] Index 'char-encoding' not found in attset(s) 23:15:32-23/07 zebrasrv(29) [warn] Index 'char-encoding' not found in attset(s) 23:15:32-23/07 zebrasrv(29) [warn] Index 'script-Title' not found in attset(s) 23:15:32-23/07 zebrasrv(29) [warn] Index 'Country-heading' not found in attset(s) etc. The biggest challenge however seems to be the re-building the relations/hierarchy between records and to present the dependencies to the users and librarian in Koha interface (i.e. to have a link upwards from individual chapter/article to the book/issue of a serials it is a part of etc. and, on the other hand side, to be able to review the book/issue and to be presented with the list of chapters/articles). My questions are: 1.Does Koha, at the current stage of development, supports that kind of inter-record hierarchical dependencies, especially book<-->chapters? 2.If yes, how could it be applied? (N.B. my study of Koha led me to the Link feature in tag definition, but it seems not to work properly: 1) the query generated by the little glass that appears after a subfield in MARC view, if the Link feature is active, (e.g. 200f: http://k3:8080/cgi-bin/koha/catalogue/search.pl?op=do_search&idx=200f,phr&type=intranet&q=<autor_name>) gives no results, whereas performed with the same author from Normal view (http://k3:8080/cgi-bin/koha/catalogue/search.pl?q=au:<author_name>) works OK. 2) The little glass does not appear (AND the subfield does not appear AT ALL) if it is 46x$0 subfield (although the subfield is present in the record and it is marked to be shown in MARK framework definition). ) I would appreciate any help / suggestions. Greetings, Janusz Kaczmarek Warsaw
