Binary Sparse Format Specification

This is part of a new effort to create a binary storage format for storing sparse matrices and other sparse data to disk.

Minutes from our meetings are available here (see also: previous minutes).

Specification

Here is a table listing the current tensor frameworks that support the format:

Language	Framework	Status	Notes
C	binsparse-reference-c	under development	converts between binsparse and in-memory sparse matrices
C++	binsparse-reference-impl	under development	converts between binsparse and in-memory sparse matrices
Julia	Finch.jl	under development	converts between binsparse and Finch matrices and tensors, supports custom format spec
Python	binsparse-python	under development	converts between binsparse and scipy.sparse matrices

The working version of the specification can be found under spec/latest/index.bs.

The spec is written in bikeshed – a variant of markdown. To render the spec locally:

To render the spec online, see api.csswg.org, or use the following commands:

Rendered versions will generated for pull requests.
