Dear all,
I know that org-mode supports links to local files via relative file:
URLs, e.g. file:filename.html. It also supports links to fragments (aka
anchors/bookmarks) in remote files via http: URLs, e.g.
http://www.example.org/filename.html#section2.
Now, is there a way to combine these? I would like to use something
like file:filename.html#section2 to link to a fragment in a file that is
in the same directory as my org file. For portability reasons I don't
want to use any other way of linking to that file than a relative file: URL.
Please read on if and only if you are interested in my reasons for
wishing for such a feature :-)
My concrete use case is that before learning about org-mode I managed my
personal knowledge in a TiddlyWiki (http://www.tiddlywiki.com/), and
some of my knowledge I'm still keeping there. (Why? See below.) The
pages ("tiddlers") in a TiddlyWiki can be accessed as fragments of the
TiddlyWiki HTML file, e.g. file:/path/to/tiddly.html#WikiPage. I have
my TiddlyWiki file in the same directory as my org file and would like
to link to specific pages of it using file:tiddly.html#WikiPage in order
to achieve a tight integration between both knowledge collections.
FYI, and really just FYI, as I don't want to start a flamewar: The one
single thing that I still like better in TiddlyWiki than in org-mode and
that I haven't been able to reproduce in org-mode is that I can organize
my knowledge in a hierarchical and linked way by tagging pages with
other pages. E.g. I could have a page OrgMode tagged with
ProductivityTool, where ProductivityTool would not merely be a tag, but
the name of another page, which contains general information about such
tools. That is, to the best of my knowledge, not possible in org-mode,
which treats outline headlines and tags as two completely different things.
Cheers, and thanks in advance for any help,
Christoph

If you search for "ID markers" in the ML archives, you will find a
proposal by me that provides mechanism for this that is non-brittle.
In the meantime maybe you can use the existing brittle mechanism for
search links (see the manual) in combination with a personal special
keyword that you never change. A possibility anyway. You might need
to change a hook.

thanks for this pointer. This is definitely helpful and interesting
information for me – when working _within_ org-mode. I am actually a
semantic web researcher and thus highly interested in giving everything
an ID that can be linked to – not just for my research, but, of course,
also for my personal knowledge management.
But my question in this thread was a different one: linking to fragments
of _external_ files, most commonly HTML files that I'd like to open
outside of Emacs in a browser.
Cheers,
Christoph

Hi Christoph,
Really?
Very strange.
I thought I had explained pretty clearly in the proposals that ID
markers can be put in comments in the /external/ files.
If you look up file link search, you will see that it is breakable by
corrupting the thing searched for.
Org IDs in external files -- which I propose to be in ID markers --
are as unbreakable as you can arrange in a practical way.
In any case, it is just a proposal, so if it doesn't work for you, no
need to use it.
Samuel

Ah, OK, sorry, I didn't notice that. But, anyway, I'm not sure if I'd
want to put such markers into all pages of my TiddlyWiki. And while
that would still be _possible_, I'm sure that there is also a use case
for linking to fragments of local HTML files that you really don't want
to change or can't change. Imagine being a non-privileged user and
linking via file:///path/to/software/manual.html#feature to some section
of the manual of a software installed by an admin user, or to some
downloaded e-book or archived web page.

BTW that reminds me of purple numbers
(http://en.wikipedia.org/wiki/Purple_Numbers), which I have seen in some
wikis. But they don't scale as well as your ID markers.
Cheers,
Christoph
