I want to get more knowledge of M43 standard, and I assumed that as a standard it should be available with all specifications for the public — or at least for purchase — but couldn't get one. The official website http://www.four-thirds.org/en/microft/ gives only a high-level overview. I want to understand the communication protocol.

Where one can get standard documentation? Is it public?


No. Micro Four Thirds is not an open standard. The specification is available to member companies, which are listed here. It's not a tiny list, but it's not large, either.

Your best bet is found on the contact page, which says (sic):

To Manufacturers considering developing or selling the Four Thirds compliance product.
