[DISCUSSION] Database schema & coding guidelines
by Paul Poulain 04 Jul '12

04 Jul '12

In the wiki page http://wiki.koha-community.org/wiki/DB_schema_bugs, an insconsistency has been noticed: primary keys column name can be: id (in authorised_values table), xxxid (cityid), xxx_id (label_id), xxxId (limitId), xxxcode (branchcode), xxxnumber (borrowernumber) => choose how to name PK and update schema accordingly The bug 7065 add a foreign key to the reserves table, so I think it's time to clearly choose how we name primary keys. The possible options are below, my opinion: 1- id alone => will result in complexity & mistakes, this option must be discarded 2- xxxxid => short option, may result in hard readability. 3- xxxxId => we haven't decided if we want UC in field names. I won't discard this option, but does not favour it. 4- xxx_id => _ still undecided in field names, I'm not sure it's much better than the xxxid one 5- xxxxnumber => number is quite long, and may result in very long field names, which is not good. I does not like this option. Let's start the discussion -- Paul POULAIN http://www.biblibre.com Expert en Logiciels Libres pour l'info-doc Tel : (33) 4 91 81 35 08

A C4::Logger module would be useful ?
by Jonathan Druart 04 Jul '12

04 Jul '12

HI all, I have developped a logging module (based on LogLite). I think it could be useful for Koha. A new system preference controls the log level (eg. level warning for production and debug for development). It can be used by a simple script or into Koha. How it works: See Bug 8190 ( http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=8190) Please have a look at that, and tell me what do you think about it. Technically, is it satisfying for you? I think it could help us to increase the code quality. Any others ideas are welcome ! ++ Jonathan

[discussion] Privacy issue (bug 3280)
by Paul Poulain 03 Jul '12

03 Jul '12

Hello Koha users & developers, The bug 3280 fixes a problem in cart sending in opac : the behaviour has changed, and for security reason, it will be possible only for logged-in users. A question has also been raised : we could also add the IP address of the sender in the mail that Koha sent. Do you think : 1- we could 2- we should 3- we shouldn't (and why) I start arguing = I think we should, and in France, I think it's a legal issue, you must be able to answer any legal request from a court (9-11, thank you :\ ) It's right we have the username, but the IP address is a good complement -- Paul POULAIN http://www.biblibre.com Expert en Logiciels Libres pour l'info-doc Tel : (33) 4 91 81 35 08

Hello koha-devel, After our discussions during the hackfest, a wiki page has been written. Now, it's time for the first patches, to see how it could look like. I made some work on bug 8309. That's not a request for signoff, but to look at the code, comment, discuss, ... Note: if you want to play with those patches, look in admin/categories.pl and testrelations.pl. You'll have to install Moose and DBIx::Class, (available on probably all linux distros) -- Paul POULAIN http://www.biblibre.com Expert en Logiciels Libres pour l'info-doc Tel : (33) 4 91 81 35 08

Bug 6557 pushed, please check localised frameworks
by Paul Poulain 29 Jun '12

29 Jun '12

Hello devel & translate, I just pushed the patch for bugs.koha-community.org/bugzilla3/show_bug.cgi?id=6557 . It fixes a nasty long-lasting problem, BUT will work only if your frameworks are OK. The popularity is based on biblioitems.totalissues field, that *must* be linked to 942$0 field. It's the default for MARC21 in english, I've fixed UNIMARC in french, *please* check your language/marc flavour. If the biblioitems.totalissues is not linked to 942$0, you'll get a nasty (and unclear, i've asked for a follow-up to have something more understandable): Tag "0" is not a valid tag. at /home/paul/koha.dev/koha-community//C4/Biblio.pm line 3870 *nengard* = this one will need a large/complete documentation ! -- Paul POULAIN http://www.biblibre.com Expert en Logiciels Libres pour l'info-doc Tel : (33) 4 91 81 35 08

Experimental Support for MARC Records as a Proper Datatype in the PostgreSQL Database by Marc Balmer Sitting in one of the nice pubs in Edinburgh during KohaCon, I had this idea to add MARC records as a proper datatype to the PostgreSQL database server. After a discussion with Marc Véron and Dobrica Pavlinusic about what that could mean, I decided to just try it and I have now a basic implementation (or, more a proof of concept). Here is some information on this: If MARC records are a proper datatype, that means they are stored right in the database, are backed-up, can be restored, replicated, etc., just with the standard database tools. If a function is provided to access individual fields of a MARC record, then this can be used in SQL expressions, e.g. for selects or to create views, etc. As PostgreSQL supports functional indexes, you can create indexes on individual MARC fields, giving you super fast access to your data. How does it look? There is a datatype called ‘marc’ for now: CREATE TABLE books ( id serial, sig varchar(16), marc_record marc ); MARC records are loaded into the database as raw, binary records, encoded in hexadecimal: INSERT INTO books (sig, marc_record) VALUES (‘a01b’, ’3030383830…..’); To access individual MARC fields, the function ‘marc_field()’ was created; it returns VARCHAR: SELECT id, marc_field(marc_record, ’020') AS isbn FROM books WHERE sig = ‘a01b’; Of course MARC fields can be used to search data: SELECT id, marc_field(marc_record, ’020') AS isbn FROM books WHERE marc_field(marc_record, ’245') like ‘whatever%’; An index on a specific field can easily be created: CREATE INDEX books_isbn_idx ON books (marc_field(marc_record, ’020')); As syntactic sugar, the expression marc_record@’020' is equal to marc_field(marc_record, ’020'). Marijana Glavica kindly let me use a MARC database of ~250,000 records to make some tests, here are some real world examples: books=# \d test_marc Table “public.test_marc” Column | Type | Modifiers ——–+———+——————————————————– id | integer | not null default nextval(‘test_marc_id_seq’::regclass) marc21 | marc | books=# select count(id) from test_marc; count ——– 246727 (1 row) How many Croatian books do they have? books=# select count(id) from test_marc where substring(marc_field(marc21, ’008'), 37, 3) = ‘hrv’; count ——- 52582 (1 row) Of course much more complex queries are possible with this, and using the right indexes it is really, really fast. One query I tested went from 8.4 seconds to 0.21 ms with the right index. That’s a speedup of 40,000 times. Thanks to Marijana, Dobrica, and Marc for feedback, interesting discussions and ideas! Feedback and suggestions are of course more than welcome at marc(a)msys.ch. Adding VIAF Autosuggest for New NAME Authorities by Stefano Bargioni The Pontificia Università della Santa Croce has written a script to enhance authority cataloguing using VIAF. While adding new authorities of type *NAME, the VIAF catalog can be browsed using its autosuggest API. The script adds a field on top of the /cgi-bin/koha/authorities/authorities.pl page. Typing three or more letters, a popup will be populated with the first ten names. Upon selecting a name, information about the sources of the authority name will be displayed, as well as the full authority record from VIAF, or LC if available. This is an initial version. The next version will try to copy the VIAF authority record into Koha. Comments and help to bargioni(a)pusc.it will be appreciated.

Re: [Koha-devel] Social library

Thanks. It's very hard to find some volunteer to help, but i think i can call someone working with me working together. I just try to tell everyone what i really want and hope. Maybe i need time to make it come true, but i think, who love Koha must answer a question: What should we do with Koha, to make our patrons stay longer and longer in our website (it means that our website is not only the place for search some books, which is easier with google, but also the place for them to talk more and more about their favorite books, share them with friends). Of course they can do with sharing on facebook, on twitter, but it's really perfect if it shares automatically with Koha. When i was young, i stayed in a library, looked at a nice girl, wondered what kind of book she was reading. Now with Koha, if i know her, it's perfect when i can see what kind of books my friends are reading, how do they think about it?... right? I know, maybe some people thought about this before but it's quite difficult. Hope that if anyone want to make it, i can help about expanding some ideas, collect some experiences. Thanks all! ________________________________ From: BWS Johnson <abesottedphoenix(a)yahoo.com> To: Quocuy <nguyenquocuy_1102(a)yahoo.com> Sent: Tuesday, June 26, 2012 1:15 AM Subject: Re: Social library Salve! > Ok! I will wait for u. If u have time, we gonna talk about it more and more > then. I'm back now. I think the overarching thing that I have to say is that it sounds like part of what you want is already done, and the parts that aren't yet done sound like logical extensions. Stephen Johnson talks about the notion of the adjacent possible in innovation, and what you seem to be talking about all seems to fall in that realm. To me, it would boil down to a few different options if you discover that precisely what you want doesn't exist yet. You could pay for support so that a developer that does know Koha can just code what you want. You could find a volunteer somewhere that knows how to code, but doesn't necessarily know Koha. The last option is to learn everything yourself and then just do it. Whatever happens, if you ensure that you upstream what you change, it would be great. I will say that your attitude helps a whole lot. You sound very positive to me. As long as you're very patient, people might get around to implementing different ideas, but the free route tends to take a very long time. There's an olde sign here that reads Fast Cheap Good You can have any 2. It's very true for Koha. :) Half the battle is trying to chunk things out to allow for easy consumption and describing precisely what you want the best that you can so that a developer can get a bead on what exactly you need. If you do a good job with the division of tasks, then it's easy for people to pick up a little scrap as in quilting and stitch things together. Cheers, Brooke
