Simon seemed to enjoy discovering that the era in which he started his career (the 80s) still has resonances today. In an experience he describes as “akin to finding a live trilobite on a fossil beach”, FLOSS Weekly 510 discovered that the MUMPS database GT.M is still alive, is now open source under the AGPL, is called YottaDB and is going strong. GT.M was (and is) the original NoSQL database, powering healthcare long before anyone thought to call it NoSQL.
YottaDB demonstrates one of the great strengths of open source, public escrow. While the copyright holders of GT.M have no interest in a public project, releasing it under an OSI-approved open source license has liberated the code and allowed K.S. Bhaskar to start a new kind of company to make it globally available.
