<H1>Purpose</H1>
|

<P>
|
|
This phrasebook is a program for translating touristic phrases
|
|
between the 15 European languages included in the
|
|
<A HREF="http://www.molto-project.eu">MOLTO</A> project
|
|
(Multilingual On-Line Translation):

|
|
<P>
|
|
It is implemented by using the GF programming language
|
|
(<A HREF="http://grammaticalframework.org">Grammatical Framework</A>).
|
|
It is the first demo for the MOLTO project, released in the third month (by June 2010)
|
|
but to be updated in the course of the project.
|
|
</P>
|
|
<P>
|
|
The phrasebook has the following requirements:
|
|
</P>
|
|
<UL>
|
|
<LI>high quality: reliable translations to express yourself in any language
|
|
<LI>translation between all pairs of languages
|
|
<LI>runnable in web browsers
|
|
<LI>runnable on mobile phones (also off-line: forthcoming for Android phones)
|
|
<LI>easily extensible by new words (forthcoming: semi-automatic extensions by users)
|
|
</UL>
|
|
|
|
<P>
|
|
The phrasebook is available as open-source software, licensed under GNU LGPL.
|
|
The source code resides in

The missing concrete syntax entries are added to the <CODE>Words</CODE><I>L</I><CODE>.gf</CODE>

files for each language <I>L</I>. The
|
|
<A HREF="http://code.haskell.org/gf/lib/doc/synopsis.html#toc78">morphological paradigms</A>
|
|
of the GF resource library should be used. Actions (prefixed with <CODE>A</CODE>, as <CODE>AWant</CODE>) are
|
|
a little more demanding, since they also require syntax constructors. Greetings (prefixed
|
|
with <CODE>G</CODE>) are pure strings.
