3 Ed-Fi Data Standard & Implementation Suite Ed-Fi Data Standard The Ed-Fi Data Standard serves as the foundation for enabling interoperability among secure data systems and contains a Unifying Data Model designed to capture the meaning and inherent structure in the most important information in the K 12 education enterprise. Ed-Fi Operational Data Store and API The Ed-Fi Operational Data Store (ODS) provides a place to store information that integrates and catalogs secure real-time data from other systems within your agency, regardless of the source and supports transactional data. The Ed-Fi ODS API provides the ability to selectively create, read, and update information stored in an Ed-Fi powered ODS, maximizing developer productivity and success. Ed-Fi Dashboards Ed-Fi Dashboards provide a starting point for developing student performance dashboards that put real-time, actionable information at the fingertips of educators. Ed-Fi Tools Ed-Fi Tools aid developers implementing the technical components of the Ed-Fi Implementation Suite. Specifically, the online Ed-Fi Validation Tool helps users streamline the testing process by verifying exchanges are working correctly.

8 Architecture JSON ASP.NET WebAPI Model Binder Resource Models Generated Model Mapper Entity Models NHibernate DB-specific SQL EdFi_ODS Web Server NHibernate ORM Mappings When the ASP.NET WebAPI framework receives the JSON payload, it is deserialized into the C# Resource class model. The data is then copied to the Entity model which matches the structure of the database 8

10 Security and Data Access Authentication 2-legged OAuth2 Authorization two-pronged approach Relationship-based: Applications are associated with one or more LEAs for which they can submit and access education data Resource-based: Applications are given the right to access or perform operations against specific resources. For example: A SIS vendor is only authorized to access or perform operations against students and staff that are associated with the local education agencies that they serve An assessment vendor can only view and modify assessment metadata and data that is specifically related to their own assessments API Profiles : Enable field-level data access policy Ed-Fi ODS / API Security & Profiles Deep Dive 9:50am) 10
