helpful to see the actual code changes for it.
It is something like Excel's PivotCache, and better to save it in
the document file.
If that, we need the approval of the ODF format proposal relate it.
OOo 3.x has a cache (ScDPCacheTable), but it isn't saved, and the
results are still created using ScDPItemData. We'll have to see how we
can put these things together. Also, you're right, we'll have to clarify
the file format handling.
A little update on the file format part:
The current plan is to extend the "ODF format version" list box in the
options dialog with an additional entry, to select between "1.2" and
"extended 1.2" ("extended" in the ODF 1.2 sense).
If "1.2" is selected, nothing is saved that is not in ODF 1.2.
If "1.2 extended" is selected (the default), extensions are saved as
"foreign" elements/attributes (this means, in a different namespace -
but accept both namespaces when loading).
Also, we want to use extensions sparingly, and generally only if a new
feature is really used. This is difficult with the cache table, where
the obvious approach is to always write it.
File format extensions are also needed for shapes in charts and notes in
Impress, so the UI and configuration change will probably be implemented
for one of these features (details will be sorted out next week, but
then I will be on vacation).
