For those of you who don't know what Delicious.com is (yes it's the same as del.icio.us), I'll just borrow their overview from their getting started page:

Delicious is a social bookmarking service that allows you to tag, save, manage, and share Web pages all in one place.  With emphasis on the power of the community, Delicious greatly improves how people discover, remember and share on the Internet.

Here on DevCentral, when new content is added, we regularly add it to various social networking sites, including Delicious.  There are some great browser plugins that help you with sharing content and I regularly use the Shareaholic Firefox plug-in.  But, it's still too much manual work for me so I figured I'd try to automate it a bit.

I previously published a PowerShell library for Twitter (PoshTweet), for TwitPic (PoshTwitPic) as well as one for the Bing Search API (PoshBing) so I figured I'd build on those and write one for Delicious.  The Delicious API documentation is defined here. 

The API is broken down into the following functions:

Credentials

• Set-Delicious.Credentials - set the client credentials for the delicious.com account.
• Get-Delicious.Credentials - get the client credentials for the delicious.com account.

Posts

• Get-Delicious.PostsUpdate - Returns the last update time for the user, as well as the number of new items in the user's inbox since it was last visited.
• Add-Delicious.Post - Add a post to delicious.
• Delete-Delicious.Post - Delete a post from delicious.
• Get-Delicious.Posts - Returns one or more posts on a single day matching the arguments.
• Get-Delicious.PostDates - Returns a list of dates with the number of posts at each date.
• Get-Delicious.RecentPosts - Returns a list of the most recent posts, filtered by argument. Maximum 100.
• Get-Delicious.AlLPosts - Returns all posts. Please use sparingly.
• Get-Delicious.PostHashes - Returns a change manifest of all posts.
• Get-Delicious.PostSuggestions - Returns a list of popular tags, recommended tags and network tags for a user.

Tags

• Get-Delicious.Tags - Returns a list of tags and number of times used by a user.
• Delete-Delicious.Tags - Delete an existing tag.
• Rename-Delicious.Tags - Rename an existing tag with a new tag name.

Tag Bundles

• Get-Delicious.TagBundles - Retrieve all of a user's bundles
• Set-Delicious.TagBundles - Assign a set of tags to a single bundle, wipes away previous settings for bundle.
• Delete-Delicious.TagBundles - Delete a bundle.

Usage:

The usage is fairly straight forward.  First you must load the functions into your runspace.  This is most easily done by "dot sourcing" the script.  Then you will call the Set-Delicious.Credentials function with your delicious credentials.  At this point you should be all set to submit bookmarks with PowerShell.  The following code creates a new bookmark for my blog with the Add-Delicious.Post function and then retrieves the entries from the last day you posted with Get-Delicious.Posts.
