Obviously, Dynamo Nodes aims to be a unified portal for Nodes, which includes Custom and Core Nodes, along with the opportunity to Search, Tag, Rate, and Comment on specific nodes and their use.
A similar indexing or glossary effort was undertaken by Thomas Vogt, and his work has been collected in a Node Book for Dynamo. You can download the Node Book for Dynamo v2 at:
I would sincerely encourage anyone who wants to work on a glossary or index like this to contact me and I will invite you as a Contributor here on Dynamo Nodes. If we work together we will be able to make and maintain the best resource for Dynamo Nodes on the web.
