CodeSpace: http://standards.iso.org/iso/19115/-3/srv/2.0
Number of items: 3

Entry | Definition
--- | ---
loose | service instance is loosely coupled with a data instance, i.e. no MD_DataIdentification class has to be described
mixed | service instance is mixed coupled with a data instance, i.e. MD_DataIdentification describes the associated data instance and additionally the service instance might work with other external data instances
tight | service instance is tightly coupled with a data instance, i.e. MD_DataIdentification class MUST be described
