No. "Meta" is the most overused bullshit term ever.
It simply means "about".
Any "mata" data has to be external.
You can't have an object with internal meta data (about itself) because that data's existence (regardless of it's content) alters the object, and is part of it.
Even if it were self-referential, it's not meta.
And even if you want to use the word meta to describe it, the shape of a physical object is certainly not meta data. If we're referring to an object as data, then the entirety of the object's physical state must be described as such.
If all else fails, lower your standards.
