The Boisot KM model is based on the

The Boisot KM model is based on the key concept of an "information  good“ that differs from a physical asset. Boisot distinguishes information from data by emphasizing that information is what an observer will extract from data as a function of his or her expectations or prior knowledge. Boisot (1998) proposes the following two key points:

The more easily data can be structured and converted into information, the more diffusible it becomes.
The less data that has been so structured requires a shared context for its diffusion, the more diffusible it becomes (Dalkir, 2011, p.82).
Boisot's model can be visualized as three dimensional cube with the following dimensions:

from uncodified to codified,
from concrete to abstract,
from undiffused to diffused.
He proposes a Social Learning Cycle (SLC) that uses the I-Space to model the dynamic flow of knowledge through a series of six phases:

Scanning: insights are gained from generally available (diffused) data
Problem-Solving: problems are solved giving structure and coherence to these insights (knowledge becomes 'codified')
Abstraction: the newly codified insights are generalized to a wide range of situations (knowledge becomes more 'abstract')
Diffusion: the new insights are shared with a target population in a codified and abstract form (knowledge becomes 'diffused')
Absorption: the newly codified insights are applied to a variety of situations producing new learning experiences (knowledge is absorbed and produces learnt behaviour and so becomes 'uncodified', or 'tacit')
Impacting: abstract knowledge becomes embedded in concrete practices, for example in artifacts, rules or behaviour patterns (knowledge becomes 'concrete') (http://www.innovators.edu.pk/node/205)
The proposed Social Learning Cycle (SLC) serves to link content, information, and knowledge management in a very effective way - the codification dimension is linked to categorization and classification; the abstraction dimension is linked to knowledge creation, and the diffusion dimension is linked to information access and transfer.(http://www.innovators.edu.pk/node/205).
