 A Java library to create and modify RO-Crates.
 The aim of this implementation is to **not** require too deep knowledge of the specification,
 and avoiding crates which do not fully comply to the specification, at the same time.

-or take a look at [how to adapt the examples from the official specification](#adapting-the-specification-examples).
