Knowledge can be defined as awareness of facts or as practical skills, and may also refer to familiarity with objects or situations. Knowledge of facts, also called propositional knowledge, is often defined as true belief that is distinct from opinion or guesswork by virtue of justification.

Describing knowledge in written or spoken language, including in the form of computer programs, we codify knowledge in the form of as Ideas, Concepts and as Systems of Concepts. Concepts represent Ideas.
We can also express knowledge in other forms than written or spoken language, for example in the form of physical entities, artefacts such as buildings, machines, visual models, styles, designs, or in visual or performing arts.
Please note that these categories may overlap: a painting or a sculpture is also an artefact. And a bungalow constructed with boulder walls is an artefact that partly consists of natural physical objects that are not artefacts.
I share my personal knowledge on Systems, Sustainability and Knowledge in my external brain The Sustainability Web , contributing to our Knowledge Commons.
