Richard Welke, Professor and Director at Georgia State University, commented:
Any process improvement or change process is a metaprocess of the process it’s targeted at. And, of course, it in turn can have a metaprocess (the process for deciding when and how to change the process improvement, or more generally BPM process). Hence it is a meta-meta-process
relative to the specific organization process or “routine” being examined/managed.

A similar argument can be made for “data”. Any data that describes other data is metadata. Metadata, in turn, can have metadata (the data that describes metadata, or more generally a repository model). Hence it is meta-meta-data relative to specific business data being managed.
I don’t think any ‘meta-” above meta-meta-process or meta-meta-data would be meaningful (add value). I could be wrong I suppose.
 This series of point/counterpoint replies is a follow-up to my post “Meta Here. Meta There. Meta Everywhere?” (March 31, 2014), which generated a surprising amount of great discussion. (Thanks all!) Refer to: http://www.brsolutions.com/2014/03/31/meta-here-meta-there-meta-everywhere/
The definition I’m using for meta- is from Merriam-Webster’s Unabridged Dictionary [3b]:
3b: of a higher logical type – in nouns formed from names of disciplines and designating new but related disciplines such as can deal critically with the nature, structure, or behavior of the original ones *metalanguage* *metatheory* *metasystem*
