Problem statement: the rocky landscape

1. “My grant requires a data sustainability plan”2. “I know I should be doing something more to protect my stuff,

but I don’t know what”3. “I don’t want to preserve my stuff, just store it forever”

In other words: a gap...between published research and underlying data

A gap...between published research and underlying data

As a result, datasets are– Difficult to discover– Difficult to access– Difficult to archive – Second-class citizens in the scholarly record

Second-class citizens in the scholarly record.

Research dataData is difficult to manage after project funding ceases

Who has it?

How do I get it?

What is it’s impact?

Where is it?

Journal articleLibraries keep it safe.

Many libraries and archives have it .

Many libraries and archives have it and will share it.

I can monitor its impact.

I know how to find it.

A choice

If the scientific record is at risk– Results can’t be reproduced– Science fails, global

catastrophe ensues

Better data publishing, sharing, and archiving
