[O] exclude certain tags from inheritance

[David Belohrad]

Dear all,

could someone help me with this?

I'm tagging my projects using different tags:

- ordinary 'whatever' tags like MARS, 2013, ProjectX ...

- tags starting with ampersand: @Me, @John, @David

- tags starting with hash #SpecificBehaviour, #LocalModification

As you can see, the first item is generic, project related, and I need
to inherit those tags within the tree. The other two items are specific:
second is to tag person who is in charge of the todo, third is a
'non-generic' tag defining very specific activity. The two I need to
have always non-inherited.

I've learned that there is org-use-tag-inheritance, which can be setup
to a regular expression. I'm not very strong in this elisp thingy. Could
someone help me to construct the expression such, that all tags starting
with @ or # will be excluded from inheritance?

many thanks
