Historical Notes

The Original Creation of the LLUP Protocol

The ideas behind LLUP were originally developed by M. David Peterson, the influences of which date back to 1996 when, as part of his contracted duties with the Site Builder Network at Microsoft, began working with the Channel Definition Format , the very first commercial implementation of the then emerging XML standard and the precursor to RDF, RSS, and Atom. It wouldn't be until late 2003, however, that the ideas that, at that point, had been slowly percolating for seven years, were first put to paper and subsequently sent off to various friends, family members, co-workers, and colleagues for feedback. Russ Miles, who immediately saw the potential of LLUP after reading the original documents, caught on fire, springing into action to help refine, polish, and put into technical presentations, diagrams, overviews, and summary's all of the details that would help define and shape the technical architecture and direction of the LLUP specification. At the same time, and as a direct result of his work on the technical documents, he began to spread the vision of LLUP to anyone who would listen, in particular the British government and military of whom, through his day job, he worked closely with on a day-to-day basis.

The LLUP Acronym

While the 'LL' in LLUP now represents 'Limited Lifetime', when the original ideas behind the protocol and subsequent draft were developed, the second 'L' had two separate meanings: 'Lifetime' and 'Location'. It has since been decided that the more important term between these two is Lifetime as it represents something that must be a part of every message: The start DateTime and expiration DateTime, where as a geographical location that the message applies to is completely optional given that not all messages have a geographical limitation to their applicability.
