What OpenTM2 is

OpenTM2 is a free, open-source Windows desktop application for managing translation projects and automating repetitive work for professional translators. Its Workbench combines a translation editor, translation memories, and project glossaries, with terminology management and alignment tools. The maker says it supports all languages, including bidirectional scripts and East Asian ideographic languages. Supported formats include HTML, Java properties, OpenOffice, XHTML, XLIFF, generic XML, and TMX translation memory databases; TMX, TBX, and XLIFF are supported for exchanging translation assets.

For software localization, the Workbench includes XLATE, an editor for translating interface strings in context and resizing dialog boxes for translated text. Scripts can automate project creation, file import and pretranslation, word counts, and export. Translators on the same local network can share translation memory databases, with offline synchronization options for remote translators. OpenTM2 is released under the Eclipse Public License. The maker provides an installer and updater, source code through GitHub, and a built-in update mechanism. Translator and developer references cover API and command-line use; technical questions and issue submissions are directed to its community collaboration site and JIRA tracker.
