Process Namespace
In emakin, after you define your data model, it's its namespace is set to be empty by default. Using empty namespace is not harmful but you may want to set an namespace to your data model if you need to exchange data with other external applications.
...
If you have an external system and need to use it 's data types in your model; you can add it as a new namespace and provide XML Schema Location to load. If you specified a schema location Emakin will be try to download schema and store in "External Xml Schema Sets" to use. If schema is not accessible from network you can manually add (with basic copy and paste) XSD file content to the "External Xml Schema Sets".

Emakin provides couple of namespaces to make an easier process development.
