Hello, I'm using org-reftable.el [1] from the contrib path of the Git repository since several months. It is a useful addition to integrate my personal archive of notes, data sheets, and pages that I tore out of journals into Org Mode documents.
Now that I wanted to refine this system, I stumbled across the other packages mentioned in the subject. It seems that they are all revisions of the same project from Marc Ihm. IIUC, org-index.el is the newest version that was preceded by org-favtable.el, org-reftable.el, and org-refer-by-number.el. Currently we have org-favtable.el and org-reftable.el in the contrib path whilst org-index.el is only available via Worg [2]. Marc, could you please clarify this confusion? Anyway, thank you for sharing this add-on!
