Ein Begriff der durch Christopher Alexander, einen in Kalifornien lebenden gebürtigen Wiener Architekten, geprägt und popularisiert wurde, vor allem in seinem frühen Werk "A Timeless Way of Building" und im gleichnamigen Buch "A pattern Language":
In einer "Childs-Just-So-Story of Pattern Language" finden sich folgende Gedanken:
Once upon a time, we wrote a book called A Pattern Language and that is how we got our name.
Now, a pattern is an old idea. The new idea in the book was to organize implicit knowledge about how people solve recurring problems when they go about building things.
For example, if you are building a house you need to go from outside to inside and there are centuries of experiments on how to do this in a "just so" way. ....
Patterns are easy to remember and set out as if-then propositions.
The book gave 253 patterns about solutions that are known to work.
People liked our book very much. We were surprised though, when we found out computer programmers liked it, because it was about building not programming. But the programmers said, "this is great, it helps think about patterns in programming and how to write reusable code that we can call upon when we need it."
Now a pattern language is about patterns being like words.
They stay the same but can be combined in different ways like words in a sentence. They can be used as in a network where one will call upon another (like a neuron network).
When you build something you can put patterns together to form a language. So a language for your house might have patterns about transitions, light, ceiling height, connecting the second floor to the ground.
A community might put together a language including patterns about public and private spaces, cars, pedestrians and parking. Using languages helps you to visualize and think about what will really make you comfortable, really comfortable.
Good languages are in harmony with geography, climate, and culture.
