The [Data, Information, Knowledge, Wisdom (DIKW) pyramid](https://en.wikipedia.org/wiki/DIKW_pyramid), also known as the wisdom hierarchy, knowledge hierarchy, information hierarchy, and knowledge pyramid, is a fundamental model in [[knowledge management]] literatures. Possibly originated from Eliot, T. S. ["Choruses from " The Rock ""](https://www.poetrynook.com/poem/choruses-%C3%B4%C3%A7%C2%A3the-rock%C3%B4%C3%A7%C3%B8). _Poetry Nook_. > Where is the wisdom we have lost in knowledge? > Where is the knowledge we have lost in information? The framework has been expanded, revised and debated by many authors. See Rowley[^1] for a review. [^1]: Rowley, J. (2007). The wisdom hierarchy: Representations of the dikw hierarchy. J. Inf.
