SIF Message Objects

SIF's Infrastructure defines a set of Message Objects (synonyms in other vocabularies include stickers and envelopes) that underpin its asynchronous data exchange capabilities. SIF Agents wrap commands and Data Objects in appropriate Message Objects to accomplish interoperability functions. Zone Integration Servers lightly parse the Message Objects to control the routing of data from Agent to Agent. SIF Data Objects are the subject of the Entity Relationship Diagram previously discussed here. To reprise: Data Objects are the implementation of SIF's data model for interoperability (students, staff, enrollment, etc.). Data Objects also happen to be the essential unit of data exchange in SIF. The following diagram illustrates an overview of SIF Message Objects (click the image to view it standalone).
