a) What is a concept dictionary?
A Concept dictionary is the fundamental building block of OpenMRS. Similar to a dictionary defining the function, meaning, and relationships of the words, the concept dictionary defines the name, code, and appropriate attributes for any observations or data collected (including medical tests, drugs, results, symptoms and conditions). To even further simplify the concept dictionary, one could compare it to an infinitely large Excel spreadsheet, where patients are represented as rows and concepts are represented by columns.

- What are concept reference mappings?
OpenMRS does not want to be a vocabulary standard. There is a lot of up-keep involved with managing universal codes used around the world. Instead, every openmrs installation is free to add new concepts, change concepts, etc in their local installation. Therefore, a concept can have any number of mappings to any number of other vocabularies, or 'concept sources'.

What are system metadata ?
System metadata are concepts, htmlforms, locations, roles, programs, etc.
The SHR database contains concepts, mappings and FOSAID numbers (per locations) that need to be preserved for it to work successfully. Therefore, It is importaint to be able to prreserve this data.

In order to backup or transfer system metadata, we may use the OpenMRS metadata sharing module. This module allows metadata to be transferred between different OpenMRS installations. It supports metadata defined in the core o external modules ( provided appropriate handlers are registered). Conflicts between local and incoming metadata can be identified and resolved. The module can be used both through an API and a web interface.
For further information on the metadata sharing module, see here.
The appopriate use of these will help you to preserve importaint system metadata.
