Data is variable

• Not always textual• Not always tabular• Not always fixed• Not always clearly authored – think of archival

provenance• Not always associated with publication

I need that data now!!! I don’t care how messy it is – I

can fix it!

I’ve wasted too much of my life fixing other’s people’s bad

data. I’m not interested until you’ve cleaned it up and

documented it. Besides, I have other things to think about

When is my dataset a new dataset?

Authorship

• Reference data – cell-level provenance versus single author data table

• ‘Cleaned’ data – can pass through many hands• Synthesis…

Potential wins

• Provenance of machine-gathered data – linking observations to instrument descriptions

• Linking data in multiple places• Data and publications and plans• Robust assertions about data versioning• Association of data with institutions

More wins

• Assertions at table and variable group level• Linking that crosses disciplinary boundaries:– Biochemistry and neuroscience– Naval history, economics and climate science

• Linking that crosses research and administrative boundaries

Challenge? Opportunity

• Linked data can improve administration of research and research data

• The real potential is in improving research quality and efficiency

• The same actors can’t do both• The actions don’t need to be in lock-step
