Log Analytics / Sentinel - Dictionary of Solutions, Schemas and Variables

Hi Team, does anyone know of a good centralised repository (like a dictionary) of Azure Solutions mapped to their Log Schemas, and a definition of the fields within each?

For example, if you take a look at the following LA workspace logs:

Thanks
