The Science of Classification  Taxonomy is often undervalued as a glorified form of filing—with each species in its prescribed place in an album

 Classification is a fundamental and dynamic science, dedicated to exploring the causes of relationships and similarities among entities.

 Classifications are theories about the basis of natural order, not dull catalogues compiled only to avoid chaos." Stephen Jay Gould (1990, Wonderful Life p.98)

"Nothing about us without us" Consumer ownership of health information

1. Health services meet my needs 2. I share my health record with my providers 3. I have rights & responsibilities on my health and my community's health 12 |

Promises: Sharing the power of information – Connecting information sources for health • Talking to each other:

meaningful exchange

– IT for those most in need - compass for equity – Creating digital tools to overcome: • The information paradox : least information on big problems • Information asymmetry : between providers and consumers • Digital divide : between have's and have-nots – Home for international public goods

Constraints in the real world  Human variability – People can’t always interoperate • Machines will never interoperate better than the people that use them

 Too many requirements … so priorities unclear – Intimately intertwined with EHRs, Public health, Decision support, Clinical care…

 Poor match of problem space & solution space – Poor definition of purpose • “What’s it for?”

 20 years of intensive work in IT has not yet provided a solution  Temptation to do more than is possible
