Multi-Parent Node -2

Multi-Parent Node -2

[aartist]

Before sometime, I asked if it is possible to have multi-parent node
in org-mode.
The answer was 'NO' because it is a hierarchical  structure.  I assume
that with 'link' mechanism, it might be possible.



I like to know, if it is possible to have multi-parent nodes at all in
emacs, not restricting to org-mode.

Yes.

What would that mean?  Can you describe a use case?

The answer was rather that org-mode nodes only can have one org-mode parent.

Yes, of course.

You mean if someone already have written something for this special
type of graph? (It is kind of bidirectional trees, don't know what it
is commonly called.)

EmacsWiki is your friend then: http://www.emacswiki.org/

I went there and searched for "graph". Not very much, but maybe COGRE
and graphviz contains something useful for you. Not sure.

Actually I wanted to mimic the structure of the 'TheBrain' program.
(http://www.thebrain.com) .  My idea was to arrange the information
linking in better way. The 'tag' mechanism of org-mode provides this
in a way, but a visual linking  can  become more useful.

For example, tagging a node, would bring all nodes with that tag
together and display in other-window.

You can already use Org with freemind, check the contrib/ directory of
org-mode.  You will just have a tree-like graph but this is a good way
to think of what we need for a more "rhizomic" graph.

Well, Org allows you to do that...  with the agenda view.

The agenda view is not as sparkling as an interactive mindmap but still,
it lets you navigate through things easily :)

For further discussion on how to make Org more friendly to mindmapping
software, please bring this discussion to the orgmode mailing list.

Thanks!
