JAXA thinks

• HP witch written in English

- is one of barrier for Japanese user - If Japanese cover page, user guide, it will helpful

• For multilingual - We do not need translated results - Japanese Keywords will be useful

Development policy

• Localize GCMD user interface

- Cover page

- Keywords

- User guide

• Do not modify original source code

- keep updating source code

Idea of Localization

NASA GCMD

Server

Establish translation Server for localize

English user

Local lang user

Internet

Internet

Example

Benefits

• can apply any kinds of language • No system environmental change for

GCMD

• As far as keep user interface, no modification need for the translation server

Methods of localization

• Localize web pages.http://gcmd.nasa.gov/index.html

– Create JSP (Java Server Pages) which contains non-locale-specific text (HTML tags).

– Create “Resource Bundle” which contains locale-specific text (English key and other language pairs).

• Localize GCMD’s “Science Keywords”.http://gcmd.nasa.gov/Resources/valids/keyword_list.html

– Create a localized “Science Keywords” database which contains English and other language pairs.

Generate dynamic pages from non-locale-specific HTML/JSP, localized

“Resource Bundle” and localized “Science Keywords” database

Localization of web pages

• Using JSP and “Resource Bundle”.– Generate dynamic page from JSP.– At this time, locale-specific text (e.g.

Japanese) are loaded from “Resource Bundle” by English key.

• Using the localized Science Keywords”.– The localized "Science Keywords“ in web

pages are dynamically generated querying a localized database by English key.

Translation of “Data Set Text Search”

• Input keyword on the web browser– When Submit button was clicked, request to the

translation server with keyword.

• Sentence and translated keyword on the translation server– If keyword was matched on the localized “Science

Keywords” database, translate it into English.

• Behave as proxy of the GCMD server– Request to the GCMD server by English keyword.– Receive response from GCMD server, and send it to

the client web browser.
