My intent is to help people understand how the SOM and SMCP work by comparing it to LwM2M, but unfortunately I feel that I don't quite yet fully "grok" LwM2M. That makes it difficult to write up a fair comparison.

For example, based on my understanding, LwM2M seems to focus on devices checking in with and being managed by a central management resource, whereas SMCP allows for a more decentralized, ad-hoc structure. SMCP devices can be centrally managed, but emphasis has been put on the ability to configure relationships between devices that don't rely on a third party. But it's unclear to me if I'm properly understanding LwM2M in making that comparison.

I believe I was looking at the LwM2M v1.1 specs while writing up the linked wiki page.
