1. Introduction

MOLTO promises a translation tool based on Grammatical Framework, a programming language for multilingual grammars. The Grammatical Framework (GF) is used in the MOLTO project to build translation systems for EU languages. The user of the MOLTO translation tool need not know how to write GF grammars. She is supposed to use domain specific grammars developed by others to translate documents in the domains covered. Basic domain language coverage does not guarantee that all terms and idioms in the translatable document are covered. The MOLTO translation tool should handle lexical gaps in a way that benefits and benefits from a wider community of translators. It should also provide fallback solutions when a text is not covered by the available grammar(s).

This report explains the components of the MOLTO translation tool API. The API is the main value because end user translation environments and tools are many and change quickly with time, while MOLTO tools should have a more long lasting value. The components of the API include at least the following (The Core API):

• translation editor
• grammar manager
• document manager
• term manager

Provisions for interfacing with further typical CAT tool components will be considered (The Extended API).

A model implementation of MOLTO translation tools based on the API will be demonstrated in the MOLTO prototype due as deliverable 3.2 in February 2012.
