This report summarizes a series of Data Sharing Workgroups that occurred in 2014 and 2015.

Purpose of the workgroups: To provide community input on topics related to data sharing functionalities in the BioSense platform.

Summary of work: The Data Sharing Workgroup (DSW) began by establishing a charter to orient workgroup members and establish a unified purpose and responsibilities. The DSW would meet regularly to describe appropriate use cases and opportunities for the sharing of syndromic surveillance data, identify appropriate partners for data sharing, and define parameters for effective sharing that adequately address data security and the principle of least privilege in data access. Initial discussions focused on two primary concerns: identification of system functionality that was needed to facilitate increased data sharing and the potential need for data use agreements to govern data-sharing relationships between jurisdictional partners. Identifying and describing system functionalities became the primary focus and resulted in a priority list of roles and functional needs/restrictions associated with each role that was submitted to the governance group for review.
