Org-mode archive with inherited tags

The issue

By default only the tags directly attached to an org record will be saved in the archive file. I want to keep all the tags attached to an org record when I archive it, even the inherited ones.

Explanation

In org-mode tags are inherited by default. In case of org tree like this:

	
Header1        :tag1:

	
* Sub Header1   :subtag1:

you may find that **Sub Header1** has `:tag1:subtag1:` tags attached to it.

This is something reflected in Agenda view. Also if you try to find headers with `:tag1:` the **Sub Header1** will be one of those even though we didn't directly attach that tag to it. That's the tag inheritance.

If you try to archive **Sub Header1** you will get this kind of record in the *_archive.org file:

	
Sub Header1 :subtag1: <--- this is the tag


  :PROPERTIES:
  :ARCHIVE_TIME: <date>
  :ARCHIVE_FILE: <original org file>
  :ARCHIVE_OLPATH: <org path>
  :ARCHIVE_CATEGORY: <org file category>
  :ARCHIVE_ITAGS: tag1 <--- this is the inherited tags
  :END:

As you can see the `tag1` is missing in the heading. It is available in the `ARCHIVE_ITAGS` though. For me it would be much better if I can see all the tags immediately in the record heading. It will also allow me to filter my archived records by those tags.

Solution

(setq org-archive-subtree-add-inherited-tags t)

It's as easy as that. Now the archived heading will look like this:

	
Sub Header1 :tag1:subtag1:

which is exactly what I wanted.
