SIF Zone

Four Elements make a SIF Zone

Software Application, Data Objects, the Agent, and the ZIS

Software Application
    * A software program implemented with a school or district
SIF Data Object
    * Sets of information shared by software applications using the rules of the SIF Specifications.
    * The contents of Data Objects are defined by the SIF Specifications
    * Data Objects are shared through SIF messages and written using standard XML notation.
SIF Agent
    * A software program, written by a vendor, that serves as the intermediary between the software application and the SIF Zone
    * An Agent is able to publish messages when events occur in its application, react to incoming events, and can request data and process responses from other applications.
    * The Agent publishes and receives messages through the Zone Integration Server (ZIS)
Zone Integration Server (ZIS)
   * A software program that serves as the central communications point in a SIF Zone
   * The ZIS keeps track of all the agents registered in the Zone, and manages all transactions between and among Agents
   * The ZIS is what enables Agents to provide data, subscribe to events, publish events, request data and respond to requests.
   * The ZIS is also responsible for all access control and routing within the Zone.
