Pimcore XLIFF 2.0- 

A standard for translation management

XLIFF = XML Localization Interchange File Format

This is an XML format for the representation of hierarchically structured contents. The format is specially designed for the low-loss exchange of translation data and the associated context information. It is XML-based and therefore extensible.

The specification is aimed at the translation industry. It specifies elements and attributes to store content extracted from various original file formats and the corresponding translation.

In the meantime, XLIFF version 2.0 is available

There are several good reasons for using XLIFF2.0

Xliff 2.0 is a little more tidy than XLIFF 1.0, and makes the separation of markup and text a little easier.

The biggest advantage over XLIFF1 is that notes and annotations for the translator can be attached   these can now be attached to the DataObject or document in the Pimcore backend as "notes".

We have published the module.

You can find it on Github or in the Pimcore Marketplace.
