Hi - I recently started schemaorg-coda.dpb.io with some tools that personally help me investigate some of the more technical aspects and changes of the Schema.org specifications. Example links:

• Changes from v29.2 to v29.3 - detailed list of property changes between the releases.
• Changes on main - same details, but compared to development source code.
• duration history - term-specific changelog across releases.
• Organization examples - based on processed RDF graphs instead of manual term tags.

It is a cleaned up version of some internal tools that I have relied on over the years. My use cases have been to identify changes for data processing algorithms, occasionally review historical definitions, find specific examples more easily, and cross-reference details with canonical source code. I wrote a little more about the background in a blog post.

Not sure if this sort of thing is relevant to anyone else, but figured I could mention it here, just in case!
