Bibliotouch

Requirements

Developed and tested with :

• Server :
  • NodeJS 7.9
  • NPM 4.2.0
  • Mysql 5.7
  • Windows 10
  • Ubuntu 16.04.2
• Browser :
  • Firefox 53 - Best compromise
  • Chrome 58 - Strugges to handle elegantly huge number of HTMLElements
  • Edge 40 - Touch events and some CSS features are buggy or disabled by default, otherwise it's OK

Installation

Setup database for first import

Bibliotouch initial document import (from Koha) is looking for a mysql database with credentials corresponding to the config file found in bibliotouch-server/config.

The db should have a table BIBLIOITEMS (corresponding to an export of the Koha database we are based on).

All the following commands are run from the root folder

Front packages installation

npm --prefix ./bibliotouch-front/ install

Front building

npm --prefix ./bibliotouch-front/ run build

Server installation

npm --prefix ./bibliotouch-server/ install

Server initial import

npm --prefix ./bibliotouch-server/ run flush This will empty the index when run and then is going to look for a mysql server to import documents from. Once the import from the mysql server is done it is going to update its records using the Koha OAIPMH url given in the config file.

Server test

npm --prefix ./bibliotouch-server/ test This will run the Express server and check that the homepage is showing

Server start

npm --prefix ./bibliotouch-server/ start This will start the web server and a bunch of processes to make sure the index is kept updated.

1. Update from the Koha OAIPMH endpoint (using the date from data/lastUpdate.json file)
   1. Authorities tree (models/authorities.js) is going to be updated
   2. Themes (models/themes.js) are recalculated
2. Set a cron job (editable in config file) to update again
3. Start the Express server

The website is then available on http://localhost:8080

If you want to change the listening port, get into package.json file and change the start script by adding --port [YOURPORT] to the command line.

Example : "start": "node app.js --port 1234"

Advanced

Modify MARCXML Mappings

The current MARCXML mapping reflects the the current use by the library of ENSSIB which mostly respects the standard which can be found at bnf.fr. However you might want to tune the mappings for your own use case. It is possible however huge changes may have you to modify some code.

Simple mapping modification

Go to config/default.json and look for koha.kohaTags, there you can find the default mappings in use.

For example : if you want to set the mapping for dewey classification value from 676.a to 677.a+b

Current default values :

"dewey" : {
    "tag" : ["676"],
    "code": ["a"]
},

modify it to make it look like this :

"dewey" : {
    "tag" : ["677"],
    "code": ["a","b"]
},

Several tags or codes edge case

Sometimes you want to map several tags or codes to a same value. The are two ways to handle this :

• Concatene all the stuff in one string
• Get an array of the different elements

To tune this behavior you have to get your hands dirty and get into the code. Look for importers/kohaImporter/kohaImporter.js and the function parseRecordObject which holds all the logic.

Add a new MARCXML field

You are up to a great adventure ! First get familiar with what is explained in Modify MARCXML Mappings. Then look for importers/kohaImporter/kohaImporter.js and the function parseRecordObject.
