The Sixth Day

6 It was said, "Let there be languages for scribbling conversations: since it is good to write down and share. Let there be three languages, one for outlining, one for foundations, and one for enriched details." And it was so. And according to the kinds of conversations there were made many outlines and foundations, called patterns of conversations. Then it was said, "Let patterns include other patterns, details include other details, so that they be fruitful and increase in number without too much scribbling. But you can even scribble fully a pattern inside another pattern, a detail inside another detail, so that they can multiply anywhere you like. Indeed let the languages be enriched with Rule of Scoping (that is Brown's decree). And let foundations rule over details, while details enrich and give feedbacks to foundations. Let this be Fundamental Rule of Conversation." So conversations can now include conversations either by name or by texts and they are built on foundations.

And it was said, "We will give all three languages a good Way of Descriptions, common to all: start from declarations of participants and channels, then move to interactions which use them: this is the Rule of Description: declaration first then description." And it was also said, "We will also give all three languages, Rules for Fast Scribbling. They will be yours for scribbling as fast as you like without ruining rigour. But you can also respect Rules for Full Scribbling if you like. It is good to be explicit (this is Matthew's decree). So be fruitful and increase in number."

And it was said, "Modellers, do not hate Programmers; Programmers, do not hate Modellers; I give each People, a whole language, and these languages will have many fruits each with enlightened seeds in it, so that you can write what you like in the style you like and get what you like. They will be yours for your hearty scribbling, do it to your heart's content. And to all modellers and programmers of the earth and all the designers and analysts—everything that has the breath of digital architecting life in it—we give these languages. And so these languages, one for foundation and one for enriched details, and many others which will elaborate these two, will work together very well, so you can work together very well."

It was said a language of assertions helps design, so it now elaborated both foundations and details. So patterns relate with each other by assertions, specifying reciprocal responsibility (this is Frankel's decree of Design by Contract).

And it was said, "Let the languages for scribbling interactions take different forms so that scribbling can be done by two- and three- dimensional drawing, for many who like drawing. And let there be good tools for scribbling, including Projection and Runtime (which are Marco's and Ray's)." And it was also said, "Let all these languages for interaction work well with other useful tools and languages which are on the earth for good reasons."

And we saw all that had been made, and it was very good. And there was evening, and there was morning—the sixth day.

Thus the languages for interactions on the earth were completed in all their vast array.

By the seventh day we had finished the work we had been doing; so on the seventh day we took rest from our work (obviously we were very tired). And we were happy (that is I hope we shall be happy) because it is always good to have tea or lunch or Vodka after all the work of creating that had to be done has been more or less superbly accomplished.

(An acute reader may guess there is a further tale which details events that took place in a garden in the east: the garden of architects, where we shall find Humanity in Digits: but that demands a different time and occasion: as is often said, there is a time for everything.)

NB: Comments on the events on the Sixth Day will be presented as independent posts, one or more for each topic: since each topic, such as DBC, will demand not a short footnote but a wholesome technical discussion.
