Custom Metadata Columns

Column	Description
Source	Depends on the inbound data type for the connector. For HL7 v2.x messages this will usually be the Sending Facility value in MSH.4.1.
Type	Depends on the inbound data type for the connector. For HL7 v2.x messages this will usually be the Type and Trigger values in MSH.9.1 and MSH.9.2.
Version	Depends on the inbound data type for the connector. For HL7 v2.x messages this will usually be the Version value in MSH.12.1. Note that this custom metadata column is not added to new channels by default, though this may be changed in the Server Settings Tab.

Name Description Channel ID The unique ID of the current channel. Channel Name The name of the current channel. Message ID The unique ID of the current message. Raw Data The raw content of the destination connector message (equal to the encoded content of the source connector message). Transformed Data The serialized internal representation of the post-transformer message data. Encoded Data The state of the message data as it exists in the transformer. Message Source Depends on the inbound data type for the connector. For HL7 v2.x messages this will usually be the Sending Facility value in MSH.4.1. Message Type Depends on the inbound data type for the connector. For HL7 v2.x messages this will usually be the Type and Trigger values in MSH.9.1 and MSH.9.2. Message Version Depends on the inbound data type for the connector. For HL7 v2.x messages this will usually be the Version value in MSH.12.1. Message Hash The SHA-256 hash of the encoded data of the destination connector message. If n

Select Data Types

The table at the top of the dialog shows all currently configured connectors for your channel. Since response transformers have their own inbound / outbound data types, for destination connectors you can expand the node in the tree and view the Response row underneath a particular destination. For a new channel, all data types are set to HL7 v2.x by default. This can be changed in two ways: The Connector table has Inbound and Outbound columns with drop-down menus. Select the drop-down arrow inside of the cell to make a selection: Use the drop-down menu in the Inbound Properties or Outbound Properties sections: Note: Since a message flows from the source connector directly to each destination connector, every destination inbound data type is always equal to the source outbound data type. Therefore, you may notice that the inbound data type is not editable for destination rows. In order to change the destination inbound data type, change the source outbound data type.

General Channel Properties

General Channel properties are configured on the Summary Tab within the Edit Channel View and include: Unique ID, name, and description. Links to Code Template Libraries: These let the channel know which custom functions are available in specific JavaScript contexts. Links to Library Resources: These let the channel know which custom Java classes are available in specific connectors and/or JavaScript contexts. Deploy/Start Dependencies: These determine which channels are dependent on this one, and also which channels are dependencies for this one. This way you can have some channels deploy and start before others. Attachment Handler: This allows you to extract pieces of any incoming message and store them separately. As a message processes through a channel, multiple copies of it will be held in memory at once (for the raw / transformed / encoded versions of a message). Attachments are stored only once, so by using them you can greatly reduce your channels' memory footprint. Message St

Edit Data Types

You can edit the properties for the destination transformer's inbound data type. A filter only has access to the inbound data type, while a transformer has access to both inbound and outbound data types. Additionally, when editing the destination transformer the inbound data type may not be changed, since it must remain the same as the source connector's outbound data type. However, you can still edit the properties for the destination transformer's inbound data type. An image of the Message Templates tab editing the inbound data type. When selecting the Properties button, a dialog opens allowing you to edit the various inbound or outbound properties for the data type. This is a subset of the view shown in the Set Data Types Window. For additional information, see About Data Types and Data Types. Parent topic: Message Templates Tab

Add a Column to the Metadata Table

By default, eight columns are shown: Id, Connector, Status, Received Date, Response Date, Errors, Source, and Type. You can add columns to and remove columns from the table, one at a time, using the Column Options icon/menu in the list's column header. Note: The Messages Lists for all channels have the same column configuration; that is, any columns added to/removed from the Messages List of one channel are added to/removed from the Messages List of all channels. You can add as many available columns as you would like, though not all will be visible onscreen at once. If all columns cannot be viewed onscreen, a horizontal scroll bar appears below the Messages List. Scroll left or right to view the desired columns/data. Removing a column does not remove its data; the data reappears when you add the column back to the Messages List. Use the following steps to add a column to the Message List. On the far-right side of the Message List column header, select the Column Options icon. On the C

Metadata Table Columns

Column Description Id The unique ID that identifies the message within the current channel. Note that a single message can have multiple connector messages for each connector (source / destinations) in the channel. Each connector message row is organized by this column in the table. Connector The name of the connector. (e.g. "Source", "Destination 1") Status The current status of the connector message. Valid values include: Source connector statuses: Received: If the source queue is enabled, this means the message has been committed to the database and added to the source queue, but has not yet been processed. If the source queue is disabled, this means the message has not yet finished processing through the source connector. Filtered: The message has been rejected by the source filter, and will not flow any further through the channel. Transformed: The message has passed the source filter/transformer, and the source encoded data has been dispatched to any destinations. Error: An error
