CL-DTYPE
CL-DTYPE is a Common Lisp library implementing the DType networking protocol, introduced by MIT Media Labs.

From FramerD: Representing knowledge in the large by K. Haase: Dtypes are designed to provide an external representation for these internal structures and must support:

  • 1. Fast conversion from external format to internal structures
  • 2. Compact representation (in terms of disk space and bandwidth requirements)
  • 3. Portability between C, C++, LISP, and Scheme (at least)
  • 4. Lightweight state-free parsing and production

Currently it is an early (0.0.1) release, still incomplete: float works incorrectly, compilation on CMUCL fails (SBCL is fine).

You can download it here.

CL-DTYPE author is Yurii Rashkovskii with significant help of Victor Sovetov.
