5. What is a
Minimum Information Standard?
The answer to this question, for a domain:
"What is the minimum information necessary
for an independent scientist to carry out an
independent analysis of the data?"
Quackenbush, 2005
For Phylogenetics, this is MIAPA:
Minimum Information About a Phylogenetic Analysis

Producers' and Consumers' attitudes
Most important

9. Half of all metadata types are
critically important to two+ subfields

10. The majority of metadata types are
easy to produce for all subfields

Producers and Consumers?

12. Metadata at work:
The Open Tree of Life Project
Conflicting Data, Conflicting Needs:
● A Single, 'Best' Tree of Life
● Access to Underlying, Conflicting Trees
13. A new research area:
Computational data provenance
...Huh?
14. A new research area:
Computational data provenance
Computational: The result of a computation
Data provenance: Where/how it came to be
As science becomes more and more
computational, we need to know more about
our data!
16. Discussion
Will our survey results predict actual behavior?
What tools, if any, will preserve and encourage
submission of computational data provenance?
Is computational data different from measurement
data, classification data, or other types of
metadata? If so, does that affect our work?
