OpenTM2
What it is
OpenTM2 is a free, open-source Windows desktop program for managing translation projects and automating repetitive work. Its Workbench brings together 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. It handles formats such as HTML, Java properties, OpenOffice, XHTML, generic XML, XLIFF, and TMX databases, and supports TMX, TBX, and XLIFF for exchanging translation assets. For software localization, its XLATE editor lets translators work with interface strings in context and resize dialog boxes for translated text. Scripts can automate project creation, file import and pretranslation, word counts, and exports. Translators on the same LAN can share translation memory databases; remote translators have offline synchronization options. OpenTM2 is released under the Eclipse Public License. The maker presents it for translators, language service providers, and enterprise workflows, and provides an installer/updater, source code, documentation, and community channels for technical questions and issue submissions.
