Hello,
now that I learned how to use a hammer, everything looks like a nail.
So I want to use Org-mode for this; my question is, did anyone do
anything similar and has some suggestions how to structure this
material?
I'm going to prepare a course in mathematical analysis (together with
the former-Scrivener-user-friend, btw). The course will be divided
into very small modules (one proof, for instance, will correspond to
*at least* one module, and often more). We want to emphasize the
connections between the ideas behind the theorems, proofs and
calculation methods, so basically the whole material will be divided
into these modules and partially ordered by the relation "... has to be
studied before ...". How to represent such a partially ordered set in
Org-mode? One idea that comes to my mind is writing a normal outline
(tree) with all the modules (possibly nested), and including links to
all "prerequisites" in every such module. Any other ideas?
Best,

Sounds for me like a typical taskjuggler project, and fortunately there
is ob-taskjuggler.el. See

Thanks, but not really. My problem is not about /TODO/ dependencies -
I may as well actually /write/ the project in a totally different
order. What I want to specify is the order of /studying/ that stuff,
which finally might be turned into links to the prerequisites in each
module or something like that.
Thanks anyway,

Do I get it correctly that taskjuggler is all about /TODO/
dependencies? If yes, it seems to be a solution to a different
problem...
Thanks anyway

I am teaching a course this fall and I am actually using org-mode as the
format of the notes (students will be reading them in Emacs). So, I will
just be putting links to org-files directly into them, and in places
where I want to remind them of previous material. I wrote up each
"lecture" in a separate file, and provide the order in a separate table
of contents file.
If you plan to export the org files, I would use org-id links in a
section at the top of each file that indicate which previous material
should be mastered. These should export as links in html or latex.

I did not do it, but still have one suggestion.
Each module could come with a name (e.g. CUSTOM_ID) and you could add a
:PREREQ: property listing all the other modules that are
prerequisite of that one.
It might then take some lisp to convert the data into an actual
dependency graph. graphviz might also come in handy for this task : it
allows to draw directed graphs easily. see below, I ended up writing
some of that lisp.
Imagine an org file like this:
#+BEGIN_SRC org
,* Module A
:PROPERTIES:
:CUSTOM_ID: A
:END:
,* Module B
:PROPERTIES:
:CUSTOM_ID: B
:PREREQ: A
:END:
,* Module C
:PROPERTIES:
:CUSTOM_ID: C
:PREREQ: A
:END:
,* Module D
:PROPERTIES:
:CUSTOM_ID: D
:PREREQ: A B
:END:
#+END_SRC
It could be translated to an graphviz code like this one very easily :
#+BEGIN_SRC dot :file dot-example3.png
digraph test123 {
{A} -> B;
{A} -> C;
{A B} -> D;
}
#+END_SRC
which then compiles into a dependency graph. (note that "{A}-> B" could
also be written as "A -> B", but an automated translation mechanism
doesn't need to do that)
Here's some more graphviz code (taken from the manpage IIRC, the
comments in french are mine) to see what it can do if you want more:
#+begin_src dot :file dot-example.png
digraph test123 {
// on peut faire un digraphe sans tête de flèches!
edge [arrowhead=none];
// créer des flèches
a -> b -> c;
// créer des flèches d'un noeud vers plusieurs
a -> {x y} [weight=10];
// donner la forme d'un noeud
b [shape=box];
// donner un nom, une couleur, etc. à un noeud
c [label="hello\nworld",color=blue,fontsize=24,
fontname="Palatino-Italic",fontcolor=red,style=filled];
// créer une flèche avec un label et un poids.
// si on diminue le poids (4, 3, 2, 1, 0), la flèche se courbe.
a -> z [label="hi", weight=60];
// label multiligne.
x -> z [label="multi-line\nlabel"];
//
edge [style=dashed,color=red,arrowhead=normal];
{rank=same; b->x};
}
#+end_src
Because I was curious, I wrote a few lines of elisp to do the
conversion:
;; call this one via M-x ...
(defun yf/org-dependencies ()
(interactive)
(with-output-to-temp-buffer (get-buffer-create "*OrgFormatDeps*")
(princ "digraph OrgDeps {\n")
(org-map-entries 'yf/org-format-dependency)
(princ "}")
(terpri)
(pop-to-buffer (current-buffer))))
;; this is a helper function
(defun yf/org-format-dependency ()
(let ((id (org-entry-get (point) "CUSTOM_ID"))
(prereqs (org-entry-get-multivalued-property (point) "PREREQ")))
(when (and id prereqs)
(princ
(concat " {"
(mapconcat 'identity prereqs " ")
"} -> "
id
";"))
(terpri))))

I'm quite curious to know how you solved the problem, since I might try
to do something similar (but probably not with Org mode). Would you like
to share your solution ?
Thanks,
