It was first published in 1980, the current version (4.0) has just been released. As for it not being well developed, that's a matter of opinion: it's sufficiently well developed to be supported by all major CAD vendors and the bulk of the spec. has been submitted to ANSI for approval. NIST (formerly National Bureau of Standards) is the controlling organization.
