* Such identifiers are always generated and maintained by the depositor themselves.
* If the definition of the identifier in ChEMBL needs to be updated by the depositor, then the same identifier must be used in another deposition, and the original definition is then overwritten.
* Identifiers must consist of a between 1 and 200 visible ascii characters.  Non-visible characters such as spaces will be stripped from both ends.

## Deposition Job.

* A deposition job is defined as the collection of files loaded together in a single run of the loader.
* The loading of a deposition job either completely succeeds to load, or it completely fails.
