Help! Is there standardization in i2s?


I have been interested in upgrading my Streamer and DAC. If I purchased a DAC and Streamer from different manufactures will their I2s's (sorry) all mate with each other?
If not, will cable manufactures make i2s patch cords?

As I understand it, I2S has no standardization, only proprietary implementations.  That seems not likely to change in the marketplace.
Really, No standard, What year are we in??? I2s has been around quite awhile. Someone better get working on that 😤 
Nostradamus and CAlifornia Psychics would agree that the 6moons article is informative…I 
looks like I might have to make my own cable.
Alvin - Thanks for the info!
I2S is an electrical specification, not a mechanical/physical one. Vendors using it outside their box normally turn it (I2S is single-ended) into an LVDS set of differential signals. The allocation of those signals to physical pins in the HDMI connector is different between vendors.
