Description in:

3. Knowledge Management Means - model and instances –
Tetherless World Constellation
Means - model and instances –
Often the model is really a schema or data model
These models are either close-world semantics or informal ontologies (see ontology spectrum)
Limits ontology ‘management’ due to heterogeneity
Success may depend on a rationalization choice, e.g. all closed or all open (world)…
Level of knowledge representation, RDF, OWL, OWL 2 is another factor
Use of ontology must drive management choices

4. Management Creation of logical collections Physical data handling

6. Knowledge Management Supposition:
Tetherless World Constellation
Supposition:
Models and formalisms will evolve as people and their communities ‘come up to speed’
Modes of use will expand, i.e. application levels will use combinations of inference, rules, query
Integration framework, mid-level ontologies with modules imported
Been an ideal to date but has been limited in application
Recent progress and emerging better practices tell us that curation (people-intensive) is essential (no formalism or tool to do this, yet)
Use cases, use cases, use case
New features of OWL 2 are looking very promising

Nope, I am not going to list them on a slide

Due to curation needs:

Yes, this is a repeat
Governance framework is / will be needed:
ESIP?
Problem: domain/ application practitioners separated from ‘technology’ practitioners
Use cases are the implementation test(s)
