QA Catalogue Web

A data quality dashboard for library catalogues

This web application provides a web interface to results of QA Catalogue for quality analysis and statistics of metadata from library catalogues.

The results in form of CSV files, JSON files, a SQLite database, images and a Solr index are made browseable on the Web with PHP and JavaScript.

Installation

In the following:

$DATADIR denotes the base output directory of data analysis with QA Catalogue
$APPDIR denotes the directory where QA Catalogue Web is installed
$CATALOG denotes the catalogue class (such as loc, bl, k10plus...)

Analyse your catalog with QA Catalogue Backend), the result will be saved in a subdirectory of $DATADIR and in Solr.

Download

Install this software into a web server with PHP enabled (Apache or Nginx with PHP-FPM).

Create a temporary directory and download the current version to an application directory served by your webserver (here we use /var/www/html/$APPDIR):

mkdir tmp
cd tmp
wget https://github.com/pkiraly/qa-catalogue-web/archive/master.zip
unzip master.zip
mv metadata-marc-web-master /var/www/html/$APPDIR

or clone the git repository:

git clone https://github.com/pkiraly/qa-catalogue-web.git /var/www/html/$APPDIR
cd /var/www/html/$APPDIR

# optionally checkout a tagged release
git checkout v0.7.0

Requirements:

sudo apt install locales gettext php-sqlite3 php-yaml php-curl composer
sudo locale-gen en_GB.UTF-8
sudo locale-gen de_DE.UTF-8
sudo locale-gen pt_BR.UTF-8

Setup

Change into the application directory:

cd /var/www/html/$APPDIR

Install PHP dependencies and create required cache directories and permissions:

composer install

The script will further tell you to change ownership of directories if the application is served as wwww-data but installed as another user.

If you also want to locally change the source code (see contributing), allow www-data to get the current state of the working directory:

sudo -u www-data git config --global --add safe.directory "$PWD"

Configuration

A configuration file in INI format is required. Prepare configuration file:

echo "dir=$DATADIR" > configuration.cnf

The catalogue class should explicitly be specified:

echo "catalogue=$CATALOG" >> configuration.cnf

Additional configuration parameters are listed below. Data type and version number when the parameter was introduced are given in parentheses:

id (string) the machine name of the data directory. By default, it comes from the URL as the path of the application (qa-catalogue). With this parameter the administrator can overwrite the path. Note: this parameter was called db previously. For compatibility reason we will support db as well for some time.
multitenant: (bool, v0.8.0) flag to denote if the site is in multi-tenant mode, i.e. it hosts the evaluation of multiple catalogues. If it is set you can specify general and catalogue-specific settings, e.g. versions=false is a general setting, while versions[loc]=false is a library specific settings, which override the previous one.

The following parameters can be set either for all catalogues (parameter=value) or for each individual catalogue (parameter[id]=...).

dir (string) the base output directory of data analysis with QA Catalogue
catalogue (string) the catalogue class given in lowercase. The value catalogue can be used for generic catalogue. Set to value of id by default.
default-tab (string) the tab which will be displayed when no tab is selected. This will be the tab which will be opened by the root URL (the landing page). If no default-tab has been set, start will be used. The possible values are: start (default), data, completeness, issues, functions, classifications, authorities, serials, tt-completeness, shelf-ready-completeness, shacl, network, terms, pareto, history, timeline, settings, about, record-issues, histogram, functional-analysis-histogram, control-fields, download, collocations.
indexName (string) name of the Solr index of a particular catalogue, if it is different from the name of the catalogue or the URL path.
dirName (string) name of the data directory of a particular catalogue, if it is different from the name of the catalogue or the URL path.
versions (bool) denotes if there are versions for a catalogue. Possible values: true (there are versions), false (there are no versions). Default: false.
display-network (bool) show or hide the network tab. Possible values: true (display the tab), or false (not to display). Default: false.
display-shacl (bool) show or hide the SHACL-based custom validation tab. Possible values: true (display the tab), or false (not to display). Default: false.
templates (string) directory with additional, custom Smarty templates for customization. Default: config.
mainSolrEndpoint (string, v0.8.0) the URL of the main Solr endpoint. Default: http://localhost:8983/solr/.
solrForScoresUrl (string, v0.8.0) the URL of the Solr core that is used for storing the results of validation. Usually this index is merged to the main core, so this property is needed on the special case when the validation is not merged. Default: http://localhost:8983/solr/. In multi-tenant mode you can specify it for a particular catalogue with mainSolrEndpoint[<id>]. (Its previous name was solrEndpoint4ValidationResults.)
showAdvancedSearchForm (bool, v.0.8.0) show or hide advanced search form. Default: false
logHandler (string) where to log to. Allowed values are file, and error_log (default).
logFile (string, v0.8.0) a path of the log file if logHandler is set to file. Make sure the file is writeable by the webserver. Default: logs/qa-catalogue.log.
logLevel (string, v0.8.0) the minimal logging level. Possible values are: DEBUG, INFO, NOTICE, WARNING, ERROR, CRITICAL, ALERT, EMERGENCY. If you set WARNING you will not receive DEBUG, INFO, and NOTICE messages. Default: WARNING.
label (string) name of the library catalogue
url (string) link to library catalogue homepage
schema (string) metadata schema type (MARC21 as default or PICA)
language (string) default language of the user interface
linkTemplate (string) URL template to link into the library catalogue ({id} will be replaced by the trimmed record identifier). This parameter does not work for all cataloueg classes.

Example:

id=bvb
display-network=0
indexName[bvb]=bayern
dirName[bvb]=bayern

setup additional directories and permissions:

sudo chgrp www-data -R _smarty cache
ln -s $DATADIR/[catalogue]/img images/[catalogue]

On Apache webserver add these lines to its configuration (/etc/apache2/sites-available/000-default.conf):

<Directory /var/www/html/$APPDIR>
  AllowOverride All
  Order allow,deny
  allow from all
</Directory>

You can access the application at http://localhost/$APPDIR.

Customization

Templates

Some parts of the web interface can be customized with local files in directory config (not existing by default) or another directory configured with parameter templates:

config/header.en.tpl and config/header.de.tpl shown at bottom of each page (right after the <body> tag)
config/footer.en.tpl and config/footer.de.tpl shown at bottom of each page (right before the </body> tag)
config/about.en.tpl and config/about.de.tpl: Additional information shown in the "about" tab.

Catalogue class

Basic properties and default configuration settings are defined in a catalogue class which extends the generic class Catalogue. The application includes catalogue classes for known libraries, but you may want to define additional changes that go beyond simple configuration settings.

Here is an example of a custom catalogue class:

class Gent extends Catalogue {

  protected $name = 'gent';
  protected $label = 'Universiteitsbibliotheek Gent';
  protected $url = 'https://lib.ugent.be/';
  protected $marcVersion = 'GENT';

  function getOpacLink($id, $record) {
    return 'https://lib.ugent.be/catalog/rug01:' . trim($id);
  }
}

$url contains an URL of the catalogue in the library website, $marcVersion is the abbreviation of MARC version used in the analyses.

Please create a new file in the directory classes/catalogue. You do not have to do any other registration. The convention is to uppercase the first letter of the class name. In configuration this name is given in lowercase (Gent => gent).

Translation

Now the user interface is translatable via gettext methods. We provide two language files (German and English). In .tpl files you can add translatable text as

{_('translatable text')}

_ is a built-in alias for the PHP function gettext. If there are variables in the translated string, in the .tpl file you should use the _t function, defined by the project, like this:

{_t('number of records: %d', $number_of_records)}

You should add the translations into locale/de_DE/LC_MESSAGES/messages.po as

msgid "translatable text"
msgstr "übersetzbarer Text"

and into locale/en_GB/LC_MESSAGES/messages.po as

msgid "translatable text"
msgstr "translatable text"

If the message string contain variables, use sprintf compatible placeholders, such as '%d' for integers, '%s' for strings, '%f' for floating point numbers etc.

msgid "Found <span id=\"numFound\">%s</span> records"
msgstr "Found <span id=\"numFound\">%s</span> records"

Of course the message identifier could be different, and dense but now I think that it is more understandable (so translatable) this way. When you add a translation please add a comment to denote which page the original text appears, such as

# completeness
msgid "by document types"
msgstr "nach Dokumenttypen"

Once you have done, you should generate the .mo files from the .po files with the following command:

composer run translate

If translations have been changed, Webserver or FastCGI respectively may need to be restarted to clear the translation cache, e.g.

sudo service apache2 restart

Please let us know if you would like to see more languages supported.

Troubleshouting: if the translation would not work you can check if a given language (locale) is available in your system. In Linux you can check it with

locale -a

If the locale (e.g. 'de_DE.UTF-8') is not available, you can install it with

locale-gen de_DE.UTF-8

Note: translation is in a very early phase.
