The SWIM service ecosystem is used to:

• understand how the various services, service developments and SWIM Registry relate to each other
• promote harmonisation by identifying opportunities for service definitions
• promote harmonisation through the use of services in multiple contexts
  
• promote harmonisation by identifying shared characteristics between services (e.g. service categories, standardised implementations)
• enable more efficient service developments by making relevant artefacts available
