PO (Portable Objects)
− Using LingoHub you don’t have to pass your PO files on to your translator.
− Translators don’t have to edit the files. Your files need to be machine readable and follow
a strong syntax
− The file won’t be readable by the gettext system if the person editing the file forgets
about a quote or uses charactersnot allowed by the used character set.

⟶ LingoHub checksthe validity of files at import. Translators use the LingoHub editor for translations.
They no longer have to deal with the syntax of PO files. After finishing translationsyou can export
syntactically correct PO files.

POT (Portable Object Templates)
− POT have the same structure as PO files, they just contain the keys (“msgid”) of your
translatable content
− Use POT files if you have chosen the strategy that your keys hold texts of your source
language (instead of generic keys)

Workflowusing POT files for translations
1. POT files are created by extracting translatable strings
form your source code or CMS.
2. You pass the POT files on to your translators.
3. Your translators import the files into their CAT tool.
4. After translations are finished, translators will create PO
files and send them back.
Workflowusing POT files with LingoHub
− LingoHub allows you to import POT files and export
corresponding PO files. That’s great for starting a
translation project.
− LingoHub offers a feature called Continuous Translation. If
you export-adapt-import your resource files, LingoHub will
detect changes automatically and keep the project in-sync
to your resource files.

− MO files are machine readable representationsof PO files.
− They are smaller in size and valid after creation.
− Using an invalid PO file might break your application. You won’t be able to create an MO
file if the source PO file is incorrect.
− The easiest way to create a MO file is:
