Jon Radoff has an interesting "7 layer model of the Metaverse" at https://medium.com/building-the-metaverse/the-metaverse-value-chain-afcf9e09e3a7 and a mapping of the recent Facebook/Meta announcements at https://medium.com/building-the-metaverse/facebook-as-a-metaverse-company-d5712198b22d.
Needless to say we all have our own variations/comments on this. For me I think that Infrastructure/Decentralisation/Spatial should be the bottom 3 layers, and really the Human Interface should be the outer one - you don't (or shouldn't) build you virtual experience on the human interface, you should build the experience and then open up to as many interface types as you can. Discovery could perhaps be split between internal discovery (how you find out about stuff in the world) and external discovery (how you find out about experiences, and particularly how one experience links to another). And should the Creator economy sit on top of the experience as in a true Virtual World prople are using the experience to create the economy, and then enhance the experience (so circular!). Perhaps something more like a network model would be more realistic (if less eye-catching) given the interconnectivities involved - it's not quite the ISO 7 Layer model diagram.
I'll have to dig out one of my old models.
Jon also has a Market Map of the Metaverse at https://medium.com/building-the-metaverse/market-map-of-the-metaverse-8ae0cde89696 - which is likely to be quite dynamic!
Jon also has a Metaverse Canon Reading Guide at https://medium.com/building-the-metaverse/the-metaverse-canon-reading-guide-9eb1b371b505
