Headerless data

From the change wiki

Headerless data is a standard for raw data files. Instead of using a file header, the exact data type is defined in the file extension. For example, File:population.data-float64-8640x4320 is a 2D array, size 8640x4320, of 64-bit floating-point numbers.

Specifications

The file extension always starts with "data-",

and then is followed by either "float32-", "float64-", "int8-", "int16-", "int32-", "int64-", "uint8-", "uint16-", "uint32-", or "uint64-",
and then is followed by numbers separated by 'x', defining the dimensions. The first dimension is always the "width": data is sequential along this dimension.

Data is encoded in binary little-endian form.

About

The standard was devised by User:Elie on this wiki, specifically for data processing. It is not a very formal standard yet.
