What is MetaCPAN?

The CPAN is one of the best things about Perl. http://search.cpan.org goes a long way towards making the CPAN searchable, but it could be so much better. The code behind http://search.cpan.org is not open source (that we know of), so we're not able to contribute back to it. Instead of coding a replacement for search.cpan.org, we're proposing a free, open web service which will provide useful data about CPAN distributions, modules and authors.

Take http://cpanratings.perl.org as an example. There is no simple way (which we know of) to query a web service in order to get a module's rating. As it stands, you need to download a .csv file, parse it and then extract the data you're looking for. This would be much easier to use if you could simply query a web service, receive a JSON data structure and then be on your way.

Getting Started

Initially this project was proposed as a web service which could be used specifically by iCPAN, an iPhone application which keeps an offline version of most CPAN modules. Here's a brief synopsis of what we were thinking.

Here's a loosely organized list of topics which merit further discussion:
