## Learning objective
In this unit you will learn ...

* Awareness for wide variability
* Strategies to harmonise data
* Data collections, initiatives (e.g. GlobaLID)

## Prior knowledge
... building upon what you already know ... 

* none

## Material
... by doing these things: 

Powerpoint/lecture
Exercise: Mapping of data sets (e.g. column titles of different datasets that need to be correlated by dragging, by click on column title more info

## Learning content

* Where to find lead isotope data?
* Handling legacy data
* Challenges in metadata (e.g. “galena” vs. “lead ore”)
* Bridging gaps/harmonise metadata
* Existing initiatives
* Advantages of FAIR and LO data

## Self check
Now you can provide answers to the following questions: 

* ...
