Introduction

This addon is an archetypes multilingual keyword widget for Plone.

How to use

As any widget for Archetypes:

from Products.Archetypes.atapi
from archetypes.linguakeywordwidget.widget import LinguaKeywordWidget
atapi.Schema((
  atapi.LinesField('subject',
     multiValued=1,
     accessor="Subject",
      widget=LinguaKeywordWidget()),
))

How it works

Keywords are stored in catalog but prefixes with language code before write and unprefixed before display. It means if you have widget / viewlet /view that access to data you must first remove language that way:

keywords = context.Subject()
linguakeywords = []
language = context.Language()
for keyword in value:
    if keyword.startswith('%s-' % language):
        linguakeywords.append(keyword[len(language) + 1:])
    else:
        linguakeywords.append(keyword)
return linguakeywords

redomino.keywordalias

keywordalias achieve same goal in a different way. With keyword alias your keywords are translated in backoffice. With linguakeywords you have just different keywords.
