Multilingual Resources

To switch language, add to query part of url:

• language= to get this resource in that language
  • example: http://www.site.org /blog/about-languages.html?language=en

• setLanguage= to set a language for that session. All resources will respond in that language until next setLanguage or explicit request for language as as above.
  • example: http://www.site.org /blog/about-languages.html?setLanguage=en

DocGroup

DocGroup is a group of documents, which are related, multilingual for instance. We can understand this group as another dimension to subdocuments and versions.

In multilingual case every document in a group is in language, but normally for the same content. Aida/Web also treat all documents in a group as identical and all have the same Url. To define which document to show you need to change a language in web session.
