Which tool allows the creation of a schema-only layer package (Ipk) in ArcGIS desktop?

The creation of a schema-only layer package (Ipk) in ArcGIS Desktop is accomplished using the Package Layer tool. This tool is specifically designed to generate layer packages that include the layer's schema—essentially, the definition of the layer's data structure, settings, and symbology—without including the underlying data itself. This is particularly useful for scenarios where users wish to share the framework of the layer while avoiding sharing the actual data, which may be sensitive or proprietary. By doing this, it allows others to recreate the same layer in their own environment, provided they have access to the original data source.

In contrast, other options serve different functions. Export Replica Schema is aimed at creating a schema for a geodatabase replica, which is related to synchronizing data across databases rather than creating a layer package. Package Map compiles both layers and their datasets into a comprehensive package, which does not fit the requirement of being schema-only. Create Schematic Folder is focused on organizing schematic diagrams and does not pertain to layer packages at all. Therefore, the correct choice stands out because it meets the specific need for creating a package that contains only the schema information.
