The Translate Toolkit aims to support version 1.1 of the ODF standard, although it should work reasonably well with older or newer files to the extent that they are similar.
Our support is implemented to classify tags as not containing translatable text, or as being inline tags inside translatable tags. This approach means that new fields added in future versions will automatically be seen as translatable and should still be extracted successfully, even if the currently released versions of the Translate Toolkit are not aware of their existence.
More complex tag uses are still needed to extract 100% correctly in some complex cases. Following issues are known:
in spreadsheets you need to put the translation in both the value attribute and the
in spreadsheets only extract strings from cells with
we don’t seem to be extracting user defined metadata
we don’t seem to be extracting strings embedded in charts (axis, caption etc.)
