In Identifier Hierarchy, specify the hierarchy that will appear in
the WorldServer Explorer. At the top level is the table, then the
identifier column or columns:
If there is more than one identifier column, you can change the order
of the columns as needed by clicking Move up (for example,
if ID and language are the identifier columns, you may want to place language higher than ID in the Explorer hierarchy).
Click Join to join the columns as a hierarchy level (for example, if you join
language and locale identifiers, then English+England, English+US, and so on will be hierarchy levels).
Choose one of the identifiers to be the asset level. The asset-level
identifier is the identifier that will become an asset in Explorer;
it is the lowest hierarchical level visible in Explorer. Content that
is hierarchically lower than the asset-level is contained within the
asset-level.
For example, you may want to designate the language
as the asset level, which means that all of the content for the table
that is in a particular language will appear as one asset in Explorer.
This saves you from having a very large number of assets generated
by individual strings.
