There are 3 ways to add your own data to Karmasphere.
The most straightforward and recommended starting point mechanism is the web site. To begin use the "create feed" mechanism. To update the data in the feed, sign in to your account and then edit your feed. Note that it may take up to a minute or two for your data to propagate throughout the Karmasphere infrastructure so don't be surprised if you can't query your data and get results with the latest data immediately.
If you want to update a feed from a remote site or automate its update, you can use Karma-Publish.
If you'd like to discuss a more formal syndication relationship then contact us. We already support many protocols and formats for automatic data syndication including rsync, ftp and http. We are happy to discuss syndication of both community and commercial data feeds.
