Overview:What is Phylogenetics?
What is Phylogenetic Data? ...many things! Source: DRAFT: Current Best Practices for Publishing Trees Electronically, 2010. Stoltzfus et al. http://wiki.tdwg.org/twiki/bin/view/Phylogenetics/LinkingTrees2010

What is aMinimum Information Standard?The answer to this question, for a domain:"What is the minimum information necessaryfor an independent scientist to carry out anindependent analysis of the data?" Quackenbush, 2005For Phylogenetics, this is MIAPA:Minimum Information About a Phylogenetic Analysis
What do we need to know to analyzethis tree?
Overview:What is MIAPA? Source: Leebens-Mack et al. 2006
Overview:Producers and Consumers attitudes Most important metadata type Least important metadata type Source: Cranston MIAPA survey, 2012 (unpublished)
Half of all metadata types arecritically important to two+ subfields Source: Cranston MIAPA survey, 2012 (unpublished)
The majority of metadata types areeasy to produce for all subfields Source: Cranston MIAPA survey, 2012 (unpublished)
How to balance the needs ofProducers and Consumers? Most important metadata type Least important metadata type Source: Cranston MIAPA survey, 2012 (unpublished)
Metadata at work:The Open Tree of Life Project Conflicting Data, Conflicting Needs: ● A Single, Best Tree of Life ● Access to Underlying, Conflicting Trees
A new research area:Computational data provenance ...Huh?
A new research area:Computational data provenanceComputational: The result of a computationData provenance: Where/how it came to be As science becomes more and morecomputational, we need to know more about our data!
Reprise:What is Phylogenetics?a perfect field for computational data provenance!
DiscussionWill our survey results predict actual behavior?What tools, if any, will preserve and encouragesubmission of computational data provenance?Is computational data different from measurementdata, classification data, or other types ofmetadata? If so, does that affect our work?
