The 211 Data Structure and Style Accelerator Group was brought together to refine existing guidance for resource data elements, structure, and style to meet the needs of 211 referral provision, and to make 211 resource data more accessible for external data sharing. Members started with the Inform USA data curation standards and HSDS data structure and focused on defining a single data structure with consistent definitions for human services data as it applies to the 211 industry across the United States. During this session, the group will share the results of their work thus far, inviting feedback to influence the final publication of National Standards for 211 Data Structure and Style.
