Subject Re: Internationalization of property values
Date Fri, 02 Mar 2007 20:18:33 GMT
JSR 283 speaks directly to this... From the latest jsr-283.doc:

> 4.11.1 Internationalization
> The mix:lang mixin node type defines a single string property, jcr:lang, that
> can be used to specify the natural language in which the content of a node is
> expressed. The jcr:lang property is based on the standard XML attribute,
> xml:lang.
> [mix:lang] mixin
>   - jcr:lang (string) mandatory
> 
> This node type is optional.
> The format of the jcr:lang property should be the same as that of the xml:lang
> attribute, that is, a language code as defined in RFC 3066 (see
> http://www.ietf.org/rfc/rfc3066.txt), examples include "en" (English), "en-US"
> (United States English), "de" (German) and "de-CH" (Swiss German).
> 
> 4.11.2 Natural Language Text
> The following predefined node type can be used for storing natural language
> text.
> [nt:naturalText]
>   - jcr:text (string)
>   - jcr:messageId (string)
> 
> This node type is optional.
> Nodes of type nt:naturalText are intended to be used in place of simple string
> properties when the content being stored is known to be text in a natural
> language (or a message ID representing such a text). The text can be
> represented within the node either directly as in the jcr:text property or
> indirectly using the jcr:messageId property, that the application would then
> use to look up the  appropriate literal text. Note that nodes that use the
> literal jcr:text property might also be assigned the mix:lang mixin type,
> which would provide information as to the language of the text.
