Had this general idea for a simple binary interchange format which describes flat arrays, specific use case being able to write import/export plugins in the native scripting languages of a few different tools, and then being able to accept the resulting files in C# and JavaScript applications.

Its design would also strongly encourage the use of SOA (struct-of-array) design, which lends itself to strong SIMD.

You can find the specification for this format here.
