Using language identifiers

American English ("en") is the default language of the MDEX Engine.

If your application contains text in non-English languages, you should specify to the MDEX Engine the language of the text, so that it can perform language-specific operations correctly.

You use a language ID to identify a language. Language IDs must be specified as a valid RFC-3066 or ISO-639 code, such as the following examples:

da – Danish
de – German
el – Greek
en – English (United States)
en-GB – English (United Kingdom)
es – Spanish
fr – French
it – Italian
ja – Japanese
ko – Korean
nl – Dutch
pt – Portuguese
zh – Chinese
zh-CN – Chinese (simplified)
zh-TW – Chinese (traditional)

A list of the ISO-639 codes is available at:

How to supply the language ID

You can supply the language ID for source data using one of these methods:

A global language ID can be used if all or most of your text is in a single language.
A per-record language ID should be used if the language varies on a per-record basis.
A per-dimension/property language ID should be used if the language varies on a per-dimension basis.
A per-query language ID should be used in your front-end application if the language varies on a per-query basis.

The following topics describe these methods of specifying the language ID for your data.
