Quoting Antoine Latter:

The only thing I'd add would be the additional actions "ReplacedBy", "ExtendedBy" and "RedesignedBy".

I was actually thinking that this was the part that HackageDB could do automatically on the page that the actionBy applied to. There should be enough information in the DB (somewhat like Roel's reverse dependencies work) and the alternative would be having to re-release a package (that you don't necessarily own) to add the actionBy field.

I wanted the second set because I may want to establish the link even if I'm not the maintainer of the second package.

I would imagine that the second set of actions would be otherwise identical, and the link would show up on either package regardless of which set of verbs was used.

Exactly. Sometimes the new package designer may be unaware of the prior art, or may be too timid to declare obviating another's work. Also, allowing for both sides to declare the link can help to serve as verification of the relationship. If someone uploads the 'awesome' package which declares itself to replace everything on Hackage, should we just accept it at face value? Moreover, a feature like this new field would be useful for pruning the list of packages shown on the index, but do we want to allow the maintainer of package A to simply fiat that package B shouldn't be shown on the index anymore? We have a nice community, but security and validation are still good things to plan into the design. -- Live well, ~wren
