There’s all sorts of wisdom in academia. It seems to have started in business schools, but LIS has taken up the banner too. It’s only a matter of time before we start awarding MSWS degrees. It’s in handbooks of Measuring System Design. This isn’t on UNC’s subscription, so I couldn’t say what the SI unit of Wisdom is, but I’ll take a guess at the kilowit. Other brave souls have attempted to identify the definitions of the Wisdom hierarchy (and why it changes to the Information Hierarchy when Information Scientists talks about it, and the Knowledge Hierarchy when Knowledge Management professionals are involved). See The wisdom hierarchy: representations of the DIKW hierarchy for one effort.
We should have plenty of time afterwards for tea and cake. “Data organization.” “Human Information Organizing Behavior.” “Knowledge Organization Systems.” What would characterize a “Wisdom Organization System?” Self Archiving has failed. Stealth Archiving is the answer. An ordinary person spends there time getting out avoiding tense situations. A repo-rat spends his time getting in to tense situations.
TThere’s a critical difference between subject based knowledge organization schemes created to organize books and other documents, (e.g. LCC, DDC, and LCSH), which are defined in terms of the things which a work is about, and rigorous, class based ontologies that are based on the properties of the things themselves. Some relationships may be valid in terms of subjects, but may not apply directly to the things themselves. For example, a car wheels are part of cars, and cars are a type of vehicle. These relationships are always* true, and are examples of two different types of hierarchical relationships - partitive (is-part-of) (BTP) , and generic (is-a-kind-of) (BTG) Always-aboutness is the combination of all the different types of hierarchical relationship - this is the Broader Term (BT) relationship. In terms of aboutness, we can easily say that everything about car wheels is always about cars, and everything about cars is always about vehicles. We can also directly infer that everything about car wheels must always be about vehicles. In other words, the always-aboutness relationship must be transitive. Transitivity doesn’t hold when you mix different types of hierarchy - car wheels are not a kind of vehicle, but that has nothing to do with the transitivity of plain unqualified Broader Term. When thinking about systems for organizing information, it’s absolutely critical to remember the difference between the document, and the thing the document is about. Or in other words:

Defining CyberinfrastructurePosted by: ses in Emperors etc., Kings, New Clothes, Presidents
When I coined the term cybrarian back in 1991, all I was trying to do was come up with a cute name for a Usenix birds of a feather session for people working on sites protocols and software for finding and sharing information on the net (We’d need a bigger room now.) It wasn’t creating a new reality - the word just sounded pretty, and would be easy to filk with. Cyberinfrastructure is different. It doesn’t scan well. Simon This is the latest version of the Doorbell -> Mammal graph; it shows the direct and indirect broader terms of doorbells in LCSH. This incarnation of the graphic adds one new piece of visual information that seems to be very very suggestive. Dashed lines are used to indicate broader term references that have never been validated since BT and NT references were automatically generated from the old SA (See Also) links in 1988.
