JIRA

I'm currently building a module to import JIRA issues (http://www.atlassian.com/software/jira/) into nodes. There's an existing JIRA Authentication module, but I can't find anything that gets JIRA issue information out of JIRA and into Drupal.

So far the module can connect to JIRA's SOAP API, pull all issues from a filter, and push basic info into nodes. The import happens each time cron runs. The module first deletes all existing JIRA Issues content. Once its in nodes its pretty simple to slice and dice the data in Drupal using views etc.

Trac[1] and JIRA[2] seem to be likely candidates whenever software development projects need issue tracking, revision control, and wiki-esque functionality all integrated nicely. Trac is itself open source, and JIRA, while not open, is at least free for open source projects to use[3].
