I'm working on an introduction on worg. Hopefully I'll have something by
the end of this week including an example org file.

Oh, OK, I'm not using this, so there might be issues there.

That's a general problem. The exporter needs to map between org and tj
terminology. In most cases this is not a problem as the terminology
comes from tj, e.g. 'limits', 'vacation' or also 'allocate'. Here I
assume that the property in org mode is named the same and capitalized
the same as in tj. I guess this should be stated in the documentation.
In other cases where the exporter needs to map between org and tj, e.g.
for effort, but also for completeness or dependency information, the
exporter is more forgiving. Specifically in the case of Effort it does
the downcase as "Effort" is an established property on org. For
completeness information it maps the TODO state (whether it is done or
not). And dependencies are taken from the BLOCKER attribute (which is
I don't know if this is a good solution. I just tried to stick to the tj
property names as close as possible and only allow different names if
those concepts and names are established in org mode under a different
terminology. Hope that clears things up a bit.

Well resource names in tj have to conform to [A–Za–z0–9_], so what I did
in the exporter is look for an ID attribute in the resource or silently
generate an id from the resource headline. So if do not specify an ID
your resource Alf will be converted (and made unique) in
`org-taskjuggler-get-unique-id'. I guess this is a bit behind the users
back and also needs better documentation. In your case the resource will
be downcased to 'alf'. I have resources like "Domain Expert", which will
be converted to "domain_expert". That's why I usually add an ID property
to resources so I can easily allocate them.

Thanks for the patches. More comments below. I have an updated version
locally which also supports optional depends attributes like gapduration
and gaplength (which were requested by T Helms on the list). I hope to
publish this on a branch in the repo.

Hm, yes. Good idea. Do you have an idea how this could be done easily in

Yes, I didn't even realize that a new version has come out as I'm still
using the old C++ Unix-only version.

Oh, OK, good catch. Does this also work if `org-odd-levels-only' is not

I'd rather have the capitalisation as closely to the tj terminology as
explained above. I'd prefer to update the documentation here.

I guess this is also a documentation issue. If you know how resources
will be named (either with an ID or with
`org-taskjuggler-get-unique-id') then it should be more clear how to do

Yes, of course. I had fixed that one already locally.
So, thanks again for the feedback. I hope to have the worg page and the
code in the branch soon so things should become clearer.
