(Firstly, I apologize if this is not the right mailing list for this question. But haskell-cafe seems to be the place to go when in doubt.) I'm using the hackage-db package (Distribution.Hackage.DB) to analyze Hackage programatically. It parses 00-index.tar and provides a mapping from package name and version to a GenericPackageDescription. I've figured out how to get most of the information I want from the GenericPackageDescription. But one piece of information that's present on the Hackage web pages that I'd like to be able to get is "Upload date", but I can't find this information anywhere in the GenericPackageDescription. Am I missing it? It looks like the modification dates of the cabal files inside 00- index.tar correspond to the upload date. Is this correct? If so, I could parse this out of 00-index.tar myself (using the "tar" package). Is that the best way to do what I'm trying to accomplish, or is there a better, less "reinventing the wheel" way that I'm missing? Thanks, --Patrick
