# Import

When importing a SmartSockets message to an EMS message, `tibemsd` sets these JMS properties:

- `JMS_TIBCO_IMPORTED` gets the value `true`, indicating that the message did not originate from an EMS client.
- `JMS_TIBCO_MSG_EXT` gets the value `true`, indicating that the message might contain submessage fields or array fields.
- `JMS_TIBCO_SS_SENDER` gets the value of the SmartSockets `sender` header field (in SmartSockets syntax).

In addition, `tibemsd` maps SmartSockets message properties to EMS properties; for details see SmartSockets Message Properties.
