Enabling or disabling languages

Open the file GeoHealthCheck/ and look for the language switcher (e.g. ‘en’,’fr’) and remove or add the desired languages. In case a new language (e.g. this needs a new translation file called *.po) is to be added, make a copy of one of the folders in GeoHealthCheck/translations/; rename the folder to the desired language (e.g. ‘de’ for german); start editing the file in LC_MESSAGES/messages.po and add your translations to the ‘’msgstr’‘. Don’t forget the change the specified language in the messages.po file as well. For example the messages.po file for the german case has an english ‘’msgid’’ string, which needs to be translated in ‘’msgstr’’ as seen below.

-#: GeoHealthCheck/
-msgid "This site is not configured for self-registration"
-msgstr "Diese Webseite unterstützt keine Selbstregistrierung"

Customizing the Score Matrix

GeoHealthCheck uses a simple matrix to provide an indication of overall health and / or reliability of a resource. This matrix drives the CSS which displays a given resource’s state with a colour. The default matrix is defined as follows:

low high score/colour
0 49 red
50 79 orange
80 100 green

To adjust this matrix, edit GHC_RELIABILITY_MATRIX in instance/
