Aresti System software was developed in the early 1990's by Alan Cassidy. It works in conjunction with the graphic and logic capabilities of Microsoft's Visio drawing software package, which must also be present in the users' computer.

Legacy versions of the Aresti software remain usable with MS Visio. Development and updates to the code and its reference database beyond 2020 however appears unlikely.
