## WTF!? Austerity
|
||
|
||
> Reinhart and Rogoff’s work showed average real economic growth slows (a 0.1% decline) when a country’s debt rises to more than 90% of gross domestic product (GDP) – and this 90% figure was employed repeatedly in political arguments over high-profile austerity measures.
|
||
<!-- .element: style="text-align:left;margin:0px;width:100%" -->
|
||
|
||
> The most serious was that, in their Excel spreadsheet, Reinhart and Rogoff had not selected the entire row when averaging growth figures: they omitted data from Australia, Austria, Belgium, Canada and Denmark.
|
||
<!-- .element: style="text-align:left;margin:0px;width:100%" -->
|
||
|
||
> When that error was corrected, the **“0.1% decline” data became a 2.2% average increase** in economic growth.
|
||

## The good, the bad, and the ugly
|
||
|
||
> Traditionally, researchers have been taught to record every detail of their work, including experimental design, procedures, equipment, raw results, data processing, statistical methods and other tools used to analyse the results.
|
||
<!-- .element: style="text-align:left;margin:0px;width:100%" -->
|
||
|
||
> In contrast, relatively few researchers who employ computing in modern science [...] typically take such care in their work.
|
||
In most cases, there is no record of workflow, hardware and software configuration, and often even the source code is no longer available (or has been revised numerous times since the study was conducted).
|
||
<!-- .element: style="text-align:left;margin:0px;width:100%"" -->
|
||
|
||
> We think this is a seriously lax environment in which **deliberate fraud** and **genuine error** can proliferate.

||

## Persistent identifiers
|
||
|
||
- We all "know" Ute Habel
|
||
- But neither her name, nor any one picture of her is a good identifier
|
||
|
||
- https://trr379.de/contributors/ute-habel is one!
|
||
- unique
|
||
- gives context
|
||
- resolves to more information
|
||
- never changes
|
||
|
||
Many parties can independently collect and associate information with `trr379:contributors/ute-habel` that is afterwards easy to identify and aggregate.

## What about something like ORCID?
|
||
|
||
https://orcid.org
|
||
|
||
- Everybody *could* have one
|
||
- Everybody *should* have one
|
||
- **Not everybody has one!**
|
||
|
||
- We cannot wait for everything to make *itself* identifiable
|
||
- We cannot require a particular global identification system for everything, because there isn't one for everything.

# What did we do?
|
||
|
||
- We did, what we did before with Ute Habel, but for reals!
|
||
- We collected metadata on *you*
|
||
|
||
- The process was uncoordinated, but structured and validated
|
||
|
||
**This was possible, because we agreed on a data model<br>
|
||
and an identifier scheme!**

# Data metadata
|
||
|
||
- This system associates data availability metadata with a<br>
|
||
*content identifier*
|
||
|
||
- This content identifier allow anyone to report information on any file content in the same way we can gather information on people
|
||
|
||
- Such *metadata datasets* allow sharing structural information on a dataset, without necessarily having to share the actual content
|
||
|
||
- These DataLad datasets are a portable datastructure that can even record data provenance metadata
