Ran into this today while surfing. Thought it would be a good addition to our resource section (assuming no one has already added it).
Credits for the chart go to Meredith Scheff-King
Credit for the joints go to Professor Jochen Gros and Friedrich Sulzer.
The digital joints and description can be found in multiple file formats for download at the following link as posted by Jochen Gros: 50 Digital Wood Joints | Flexible Stream
There are also some projects and their files available at that site if you poke around a bit.
