So let's look at the bird and see what it's doing -- that's what counts.” -- Richard Feynman We need systems that better describe the concepts we employ Science is dynamic Concepts used change and evolve Concepts are situated … in place, in time, in tasks, in knowledge schemata, among individuals and communities Thus, static, unsituated concepts (and ontologies and knowledge maps) will produce static science We need methods to support dynamic and situated concept development, sharing, and application What’s in the soup? A nexus of knowledge structures (Whitehead, 1923) Situations in CyberInfrastructure Creation Application Represented by Who did it? Who should use it? Collections of people Where was it made? Where does it apply? Collections of sites / scales When was it made? When does it apply? Collections of temporal intervals How was it made? How should it be used? Collections of methods and data Why was it made? Why should it be used? Collections of research questions, motivations, theories 1.
