Examples for Topological Sorting on Large DAGs

Question

I am looking for real world applications where topological sorting is performed on large graph sizes.

Some fields where I image you cou

Answer 1

I'm not sure if this fits what you're looking for but did you know Bio4j project?

Not all the contents stored in the graph based DB would be adequate for topological sorting (there exists directed cycles in an important part of the graph), however there are sub-graphs like Gene Ontology and Taxonomy where this ordering may have sense.
