How do you manage the String Translation Process?

Question

I am working on a Software Project that needs to be translated into 30 languages. This means that changing any string incurs into a relatively high cost. Additionally, tra

Answer 1

The localised projects I've worked on had 'string freeze' dates. After this time, the only way strings were allowed to be changed was with permission from a very senior member of the project management team.

It isn't exactly a perfect solution, but it did enable us to put defects regarding strings on hold until the next release with a valid reason. Once the string freeze has occured you also have a valid reason to deny adding brand new features to the project on 'spur of the moment' decisions. And having the permission come from high up meant that middle managers would have no power to change specs on your :)

There are a number of major issues that need to be considered when internationalizing an application.

• Not all strings are created equally. Depending upon the language, the length of a sentence can change significantly. In some languages, it can be half as long and in others it can be triple the length. Make sure to design your GUI widgets with enough space to handle strings that are larger than your English strings.
• Translators are typically not programmers. Do not expect the translators to be able to read and maintain the correct file formats for resource files. You should setup a mechanism where you can transform the translated data round trip to your resource files from something like an spreadsheet. One possibility is to use XSL filters with Open Office, so that you can save to Resource files directly in a spreadsheet application. Also, translators or translation service companies may already have their own databases, so it is good to ask about what they use and write some tools to automate.
• You will need to append data to strings - don't pretend that you will never have to or you will always be able to put the string at the end. Make sure that you have a string formatter setup for replacing placeholders in strings. Furthermore, make sure to document what are typical values that will be replaced for the translators. Remember, the order of the placeholders may change in different languages.
• Name your i8n string variables something that reflects their meaning. Do you really want to be looking up numbers in a resource file to find out what is the contents of a given string. Developers depend on being able to read the string output in code for efficiency a lot more than they often realize.
• Don't be afraid of code-generation. In my current project, I have written a small Java program that is called by ant that parses all of the keys of the default language (master) resource file and then maps the key to a constant defined in my localization class. See below. The lines in between the //---- comments is auto-generated. I run the generator every time I add a string.

public final class l7d {
...normal junk


/**
 * Reference to the localized strings resource bundle.
 */
public static final ResourceBundle l7dBundle =
        ResourceBundle.getBundle(BUNDLE_PATH);

//---- start l7d fields ----\
public static final String ERROR_AuthenticationException;
public static final String ERROR_cannot_find_algorithm;
public static final String ERROR_invalid_context;
...many more
//---- end l7d fields ----\
static {

    //---- start setting l7d fields ----\
    ERROR_AuthenticationException = l7dBundle.getString("ERROR_AuthenticationException");
    ERROR_cannot_find_algorithm = l7dBundle.getString("ERROR_cannot_find_algorithm");
    ERROR_invalid_context = l7dBundle.getString("ERROR_invalid_context");
    ...many more
    //---- end setting l7d fields ----\
}

The approach above offers a few benefits.

1. Since your string key is now defined as a field, your IDE should support code completion for it. This will save you a lot of type. It get's really frustrating looking up every key name and fixing typos every time you want to print a string.
2. Someone please correct me if I am wrong. By loading all of the strings into memory at static instantiation (as in the example) will result in a quicker load time at the cost of additional memory usage. I have found the additional amount of memory used is negligible and worth the trade off.

Not only did we use a database instead of the vaunted resource files (I have never understood why people use something like that which is a pain to manage, when we have such good tools for dealing with databases), but we also avoided the need to tag things in the application (forgetting to tag controls with numbers in VB6 Forms was always a problem) by using reflection to identify the controls for translation. Then we use an XML file which translates the controls to the phrase IDs from the dictionary database.

Although the mapping file had to be managed, it could still be managed independent of the build process, and the translation of the application was actually possible by end-users who had rights in the database.

I'm not sure the platform you're internationalizing in. I've written an answer before on the best way to il8n an application. See What do I need to know to globalize an asp.net application?

That said - managing the translations themselves is hard. The problem is that you'll be using the same piece of text across multiple pages. Your framework may not, however, support only having that piece of text in one file (resource files in asp.net, for instance, encourage you to have one resource file per language).

The way that we found to work with things was to have a central database repository of translations. We created a small .net application to import translations from resource files into that database and to export translations from that database to resource files. There is, thus, an additional step in the build process to build the resource files.

The other issue you're going to have is passing translations to your translation vendor and back. There are a couple ways for this - see if your translation vendor is willing to accept XML files and return properly formatted XML files. This is, really, one of the best ways, since it allows you to automate your import and export of translation files. Another alternative, if your vendor allows it, is to create a website to allow them to edit the translations.

In the end, your answer for translations will be the same for any other process that requires repetition and manual work. Automate, automate, automate. Automate every single thing that you can. Copy and paste is not your friend in this scenario.

Answer 5

If available, use a database for this. Each string gets an id, and there is either a table for each language, or one table for all with the language in a column (depending on how the site is accessed the performance dictates which is better). This allows updates from translators without trying to manage code files and version control details. Further, it's almost trivial to run reports on what isn't translated, and keep track of what was an autotranslation (engine) vs a real human translation.

If no database, then I stick each language in a separate file so version control issues are reduced. But the structure is basically the same - each string has an id.

This google book - resource file management gives some good tips

You can use Resource File Management software to keep track of strings that have changed and control the workflow to get them translated - otherwise you end up in a mess of freezes and overbearing version control

Some tools that do this sort of thing - no connection an I haven't actually used them, just researching
