Description Jerome Fenal 2013-12-18 09:50:14 UTC
Problem description: 

When creating templates, you usually start with a basic branding which is after declined over variations (backgrounds for instance), but should retain the main attributes, such as styles, etc.

It would really be interesting, as with styles, to have a hierarchy of slide masters, with the same workflow as styles (create new master from this master), identical, which you can change the needed attributes only.

Currently, without the ability to even copy slide masters, the workflow is to write down every single step of customisation for a master, and restart all over again for another one with only different attributes (such as style list, frame placement or just background).

With inheritance, it would enable to modify the top-most slide master, and have attributes such as fonts, colors (to adapt to a different background image for instance) et al. modified on all children, the same way it works with styles.

Steps to reproduce:
1. Go to View => Master => slide master
2. Try to create a new slide master from an existing one
3. Modify the new slide master for the only attributes needed.

Current behavior:
not possible. You cannot even copy an existing slide master. (BZ#45617 at https://bugs.freedesktop.org/show_bug.cgi?id=45617)

Expected behavior:
There should be a context sensitive entry in the Slide pane on each slide master, that enables the "Copy slide master" or better "Create new slide master from this one" which would retain inheritance.

This will likely require a change to the ODF specification. Currently ODF v1.2, Part 1, §10.2.4 states:

> The <draw:page> element is a container for content in a drawing or
> presentation document.
> ...
> The <draw:page> element has the following attributes: ... draw:master-page-name 19.194 ...

ODF v1.2, Part 1, §16.9 states:

> In drawing and presentation documents, the <style:master-page> element is
> used to define master pages as common backgrounds for drawing pages. Each
> drawing page is directly linked to one master page, which is specified by 
> the draw:master-page-name attribute of the drawing pages style.
> ...
> In drawings and presentations, master pages can be assigned to drawing 
> pages using a style:parent-style-name attribute.[1]
> ...
> The <style:master-page> element has the following attributes: 
> draw:style-name 19.219.27, style:display-name 19.472, style:name 
> 19.498.2, style:next-style-name 19.499.2 and style:page-layout-name 19.504.

[1] Note that the wording here may be inaccurate ("style:parent-style-name" should probably read "draw:master-page-name"). Refer https://issues.oasis-open.org/browse/OFFICE-3679

In other words <draw:page> (Draw/Impress page) can have a master page (via the draw:master-page-name attribute) but there does not appear to be any mechanism (parent attribute) by which a <style:master-page> element (master page) can have a parent of another <style:master-page> element. Doing so would also likely complicate ODF documents considerably. 

Status set to NEEDINFO until developers / OASIS expert can comment further on the feasibility of this enhancement.
