It sounds like you want to use tables like key-value stores. I think adding such behavior directly to Org-mode would overly complicate the data structures passed between code blocks (which currently only consists of scalars and tables). However, maybe the following could work.
Here's an example table with key/value data. #+name: table | keys | values | |------+--------| | foo | 1 | | bar | 2 | | baz | 3 | | qux | 4 | Here's a code block which can access the data in such a table by key. This could be added to the library of babel to make it usable from any Org-mode file. #+name: by-key #+begin_src sh :var data="" :var key="" echo "$data"|awk "{if(\$1 == \"$key\") print \$2}" #+end_src And here's an example usage. #+headers: :results verbatim #+begin_src sh :var foo=by-key(table,"foo") :var baz=by-key(table,"baz") cat <<EOF Pulling the data from the above table we find that foo is $foo and baz is $baz. EOF #+end_src #+RESULTS: : Pulling the data from the above table we find : that foo is 1 and baz is 3.
