Re: [office-collab] Merge Enabled Change Tracking in Calligra

["Dr. Peter Rakyta" <rakyta.peter@multiracio.hu>]

Hi Svante!

Iam glad that you could try out our work. Until now we mainly focused on text manipulation (addition, deletion), but we have already started the work
regarding the support of style/format/tables changes. The main code parts are already developed, but there are still some bugs to fix in there.
So, we are planning to continue the work on the MCT in Calligra, however, I think we would need more feedback from the SC regarding the standard
itself. For example, since all the ODF implementations use their own internal document model, we are not sure about the very details of the format
change operations. That is, for example, what is needed to be specified...
Thus, I think we will continue with the support of text operations in tables, since we had already several discussions about this issue in the past.

(In principle the redo.xml file contains change operations that were taken back in the documents. Thus, the redo.xml file would be filled with data if
you revert the document into an earlier revision by the dialog window. This way we could retain the reversibility of all operations on the document.)

Best regards,
Peter
