Merging
Merging works occurs in 2 steps:
1. Linking works
Using features from the source data to calculate which works are linked.
e.g:
the
BNumber
from a Calm recordMarcfield
776$w
linking a Sierra record to it's digitised counterpart
This is carried out by the transformers of the respective sources data.
How are works currently linked?

2. Merging linked works
Merging works consist of a few steps
Choose a field to be merged e.g. items
Choose a target - the work that we will merge into.
e.g. Works from Calm
Choose the sources - works that will be merged into the target.
e.g. Sierra works with a single item
