Current Status

On Hold

This project was completed for Google Summer of Code but was not able to be merged into Banshee until months later. The main tag reading framework in Banshee had moved to Gstreamer which does not support Creative Commons tags. Another Google Summer of Code project this year was able to get a patch to Gstreamer to make this possible. When I have more time, I will try and recreate this plugin and project for Banshee.

What is it?

ccBanshee is a Google Summer of Code (SoC) project that enables Banshee users to view, verify, and manipulate license metadata embedded in media files. Verification is the main goal of this project and is explained in greater detail on the MP3 page.

This project has three parts to it:

How Does it Work?

Valid licenses
When your songs are imported or played, the license metadata is verified.
If the claim is valid, the appropriate logo is displayed to represent the valid license.

Viewing license metadata Toggle the license column
Users can view the song license metadata URL by opening the
"Edit Song Metadata" window and clicking the Advanced Properties tab.
The license column can be toggled
on and off via the Columns dialog.

Where to Get it?

  2. Run Banshee.

Google SoC Roadmap (2006)

Project start (May 23)

May 24

  • Planning and Design
    • Poke around in code and network with other developers

Notes: I'm in Russia durring this time and do not have adequate computer resources for coding.

June 11

  • Lay out Banshee code for initial proof-of-concept code
    • Modify database to handle basic license information
    • Update library view to show database changes

Notes: The current state of Banshee will make modifying the database and PlaylistView difficult. The library view is hardcoded and a large amount of time will have to be devoted to designing an acceptable license view addition.

June 18

Notes: Many updates have been made to the way license metadata is storied in the ID3 tags. More attention will be given to updating entagged-sharp to these changes if not already done.

June 25

Mid-project (June 30)

July 2

  • Add claim validation functionality
    • Write necessary network code
    • Implement XML parsing of page claim validation

July 16

  • Add support for other media types such as OGG

July 23

  • Banshee plugin abstraction (tentative)
    • Modify and update Banshee plugin API to handle database changes and library view access
  • Abstract Banshee-ccLicenser to plugin API
