Svante,

The chat notes from Jan 13 2016:

anonymous morphed into Jos van den Oever
Patrick: I am getting repeated call fails from Skype. will try again
in just a minute
Patrick: Andras Timar, Jos van den Oever, Patrick, Peter Rakyta - in
attendance
Patrick: How are paragraphs counted? in what order?
Patrick: changes have to be ordered, only one change can win
Patrick: one actor has the role of judging who comes first
Patrick: conflicts between writing in a table cell and someone deletes
a column
Patrick: webodf presumes everyone is in real time and do whatever they
want, resolve conflicts in real time.
Patrick: asynchronous editing would be a much different situation
Patrick: two kinds of collaboration, real-time, interchange of edits
and asynchronous collaboration
Patrick: both can be addressed with an immutable document scenario
Patrick: smaller set of features for real time collaboration because
of the difficulty of managing the changes
Patrick: larger set of features for asynchronous change tracking
Patrick: with OT, could move a change that causes conflict to the end
of the stack and apply the other changes
Patrick: transforming the operations and not as applied to the document
Patrick: could transform XPath statements for application to the documen
t
Patrick: There is the immutable document plus the changes -
Patrick: The hard part is coming up with the 1. addressing system
Patrick: Second part would be the operations supported, different for
real time versus asynchronous
Patrick: third, format to store the changes
Patrick: many forms to store - real time would exchange the messages -
format messages, but also the format stored in document -
Patrick: fourth messaging protocol - would need to be specified

raph.js
Jos van den Oever:

.js
Patrick: cursor is part of the document
Patrick: only transformations that can handle conflict are in webodf -
immediate collaboration
Patrick: Next 27th January 2016 - at 15:30 UTC
Patrick: Continue discussion of proposal
Patrick: Libre Office is talking about collaborative editing
Patrick: Libre Office has a new window feature, distribute the view of
the document, accept remote keyboard as well, keyboard sharing over
the network
Patrick: do need MS or Libre Office interested - No one from Open Exchan
ge
Patrick: if we can fix change tracking, in such it can extended to do
collaboration

Those attending would like to meet again on 27 Jan 2016, so if you
could push out an agenda, etc. ?

Hope you are having a great week!

Patrick
