In the Message Streams workspaceEvents workspace, you can search by event type and if you bring up Message Stream process only, you can create and manage see options and additional columns specific to message streams and specify message stream options. Message Message streams are Eagle's rules-based packaged instructions for extracting, transforming, and loading data from multiple file formats into and out of Eagle databases. You can manage data triggered and scheduled streams and copy and customize Eagle-provided default streams. To schedule message streams, access the Schedule workspace and create and schedule Message Stream Process events.

Note
Eagle recommends that you do not create custom message streams with eagle_* names and that you do not change or delete Eagle's default message streams.
About Data Formatting Files
From the Message Streams workspace, you can access and modify data formatting files used by message streams to transform and prepare data for loading into and out of Eagle databases. Reviewing and modifying data formatting files may be useful when troubleshooting message stream issues.
Each message stream specifies data delivery instructions (inbound or outbound in relation to Eagle databases), supports a single data format, and uses a single Ruleset file. A Ruleset file directs data in the message stream to the appropriate Rule file for formatting based on the message type. For example, if the message stream is designed to load security reference data, the Ruleset file may route fixed income securities to one Rule file for processing and equity securities to another Rule file.
For inbound message streams, the Rule file parses the incoming data and performs any additional lookups and validations. The data elements are then mapped to the Eagle tag format to allow loading into Eagle databases. For outbound message streams, the Rule file maps the data extracted from Eagle databases to the external system's specified format and performs any additional processing, if required.
Note
Eagle also supports the Eagle ML 2.0 XSD specification with a set of generic XML-based interfaces described as XSD and implemented on the Message Center framework as message streams. Eagle ML allows you to exchange data with increased accuracy and achieve optimal data exchange efficiency. For more information about EagleML, visit the EagleML wiki pages.
