How reset works in data, format, context, and service externalizers
The reset process for the data, format, context, and service externalizers can update their tags in memory using an updated file, add definitions if they do not exist, and remove definitions from memory. The following table summarizes what happens when you reset a definition. In the table, def1 is the definition in memory and def1' is the updated definition. A hyphen indicates no definition. The first column of the table shows the definition in memory before the reset process, the second column contains the updated definition, and the last column describes what the reset process did.
