Just heard that WPML, the WordPress Multilingual Plugin, has added XLIFF interface to streamline translation of WordPress websites.
With the new XLIFF interface, we can now use CAT tools on WordPress sites. WPML's XLIFF interface works with any CAT tool; it has been tested with Trados, Déja Vu , SDLX, AcrossA, Wordfast, MetaTexis, StarTransit Satellite PE, OmegaT and memoQ.
This will allow both translation agencies and freelance translators to leverage their existing infrastructure, increasing translation quality and reducing costs, and we'll cut down translation time (and cost) by 50%.
Has anyone tried it yet?
