CollectiveAccess is designed to be fully localizable. We are working to get CA translated for use in as many languages and locales as possible. To learn more about the mechanics of creating a new translation, read on.

Components of a Translation

Translating CollectiveAccess into your own language requires that you translate three distinct sets of text:

  • User interface text: like other localizable applications, CollectiveAccess has a list of text messages (“strings”) that require translation. These messages are presented to users while the application runs and do not vary from installation to installation and configuration to configuration. Therefore all users of CollectiveAccess who speak a given language can benefit from a user interface text translation for that language.

  • Date/time parser settings: the date and time parser – the piece of code that interprets and outputs dates – has its own language specific settings that must be defined in a translation. These settings include not only translations of the months of the year and other date-related text, but also locale-specific values that affect the formatting and presentation of dates. As with user interface text, these settings are generally useful to all speakers of a language. They do not vary between configurations.

  • Installation profiles: profiles contain installation-specific configuration information about every data element in your system, as well as controlled lists, relationship qualifiers and more. The names, descriptions and values of these configuration elements are translated into your target language within the profile, and then loaded into the database at installation time. Since configuration profiles are often specific to a single user (or group of users), they usually contain only the language(s) used by the author. This means that even if there already exists user interface and data/time parser translations for your target language, it is likely you will still have to translate your desired installation profile.

The default language used in CollectiveAccess code is English, so all user interface text translations are from English to the target language. Similarly date/time parser settings are usually translated using the English settings file as a starting point. Pre-made installation profiles are in the preferred language of the author. All standards-based profiles created by the CollectiveAccess project use English.

Editing User Interface Text

CollectiveAccess uses the Gnu GetText system for managing translations of user interface text. GetText stores both original English-language messages as well as translations in an editable file with the .po extenson. Using a special utility one can convert the .po file for use in the running application as an .mo file. Note that only .po files are editable. .mo files are derivatives designed for optimal performance.

User interface translations are stored in the app/locale directory. Each specific locale (a “locale” is the combination of a language and a culture) is represented with a directory. Inside each directory are two files: messages.po and

For editing translations, we are using online tool Transifex, where you can submit translations (and later review them). If your language or language variant is not enabled on Transifex, write us to and we will create it. After translation completion contact us, and we will copy translation to application sources.

Creating a Localization File for the date/time Parser

The next step is to localize the date/time parser. To do so copy the English language date/time parser settings file in app/lib/Parsers/TimeExpressionParser/en_US.lang to a file with your locale in the name in app/lib/Parsers/TimeExpressionParser and edit to suit. The file includes comments describing the meaning and format of various settings.

Localizing an Installation Profile

At this point you have a translated application. You still need a translated configuration, however. If you decide to use an existing [[installation_profile]] as the basis of your system then you will likely need to edit the profile adding localized text as needed. All display text in a profile is tagged with a locale string and supports specification of multiple locales. Simply add your translation alongside the existing text tagged with your selected locale.

Installation-specific Translations

In some cases the terminology used in the translations in app/locales are not quite what you want. Naturally, you can modify the terms used in the locale files to suit your purposes. However, this approach comes with a problem: you risk losing your changes when updating your CollectiveAccess installation, as the standard locale files in the update will overwrite your changes.

To avoid this problem, CollectiveAccess supports installation-specific locale files. Simply create a directory for your locale in app/locales/user and use it to house your custom messages.po and CollectiveAccess will always use an installation-specific locale, when present, in preference to the standard locale files.

Translating Pawtucket

Pawtucket uses a similar system for localization. It has locale files in app/locale and date/time parser settings in app/lib/Parsers/TimeExpressionParser.
