Somewhat tangentially related: I am currently creating a package that will allow people to maintain a database of LaTeX notes, and the Julia package will automatically be able to parse this database of LaTeX notes to extract citations, references, and it will allow authors to generate graph diagrams depicting the inter-relationship and dependencies of definitions, theorems, calculations, references, and results. It might be possible to substitute it in place of a docs system in the future, but for now it’s a prototype concept for maintaining a body of research and citations and making it into a computational graph database.
My hope is to have it fully functional by October, but the prototype is moving along nicely, 0.7+ only.
