2. ErlPort
Uses Erlang port protocol to simplify connection between languages

3. ErlPort
! Released 1.0.0alpha at Jun, 2013
! 488 stars (Github)
! Supports Module-Function-Arguments (MFA) API (chain code)

4. Erlang Ports and Port Drivers
! byte-oriented interface to an external program
! Erlang can communicate with it by sending and receiving lists of bytes,
including binaries

5. Erlang External Term Format

Erlang
! As Erlang has a fixed number of types, there is no need for a programmer
to define a specification for the external format used within some
application
