A custom type describes a specialized sub-entity that extend a standard LOGS entity model by additional customized fields that are ordered in customizable sections.
Example:
Imagine a group that does NMR & EPR experiments, both methods use the LOGS core entity-type “Samples”. To emphasize the different type of samples used in the experiments for better discrimination, easier filtering and accurate meta-data tracking, an admin creates the following custom types:
-
NMR Sample,
-
EPR Sample.
The customized types extend the standard meta-data fields by the following custom fields & sections (for reference see Custom fields):
NMR Sample
