Property
Description
Publishable
Specifies whether the document type can be published and subscribed to.
Connection alias name
Name of the messaging connection alias to use with this publishable document type. The messaging connection alias specifies which provider will receive and route instances of the publishable document type. A value of DEFAULT indicates that default messaging connection alias will be used.
Connection alias type
Displays Broker or Universal Messaging to indicate which messaging provider is used by the selected alias. This property will be blank if the document type cannot be published to a messaging provider.
Provider definition

Specifies the format used to encode and decode instances of this publishable document type.
Select...

IData
A serialized IData object. An IData object is the universal container that Integration Server uses to receive input and deliver output. An IData object contains an ordered collection of key/value pairs.
When a document is encoded as IData, triggers that subscribe to the document type can specify provider filters for the _properties header only.
Protocol buffers

When a document is encoded as a protocol buffer, triggers that subscribe to the document type can specify provider filters for the body of the message only. Note that the body of the message includes the headers as well.
Note:
The Encoding type property applies to publishable document types used with a Universal Messaging connection alias only. The Encoding type property will be blank for other types of messaging connection aliases. For example, if the publishable document type uses a Broker connection alias or the IS_LOCAL_CONNECTION connection alias, the Encoding type property is blank.
