The Data Structures Committee maintains legacy 9-1-1 data formats (such as ALI/MSAG) and is responsible for the definition and maintenance of NG9-1-1 Functional Element interface specifications. As NG9-1-1 FE interfaces leverage existing open standards where possible, and NENA-defined standards are developed to be open, the Data Structures Committee is tasked with monitoring and providing input into standards developed by other organizations, in addition to standards developed within NENA. Due to the complexity and breadth of the topics involved, document development is normally achieved by organizing a working group and gathering input from NENA members with specific technical and/or operational expertise.

- XML Schema Development:
Addresses data formats and protocol technical issues that impact data elements as part of the overall 9-1-1 architecture. This subcommittee has overall responsibility for the Data Technical Standards document 02-010 and all XML schemas. Calls are held as needed.
- GIS Data Model for NG9-1-1:
This document defines the Geographic Information Systems (GIS) database model that will be used to support the NENA Next Generation 9-1-1 (NG9-1-1) systems, databases, call routing, call handling, and related processes. Calls are Wednesday's at 10:30 am to Noon ET,
- NG9-1-1 Additional Data:

- Class of Service (COS):
A Class of Service WG has been organized to address changes that may be required within NENA documents to support emerging call types and the appropriate Class of Service (COS) values to identify them. The WG will begin, initially, on a review of COS within the context of E9-1-1 and recommend changes to impacted NENA documentation. Once complete with this initial process, the WG will then consider the importance of COS within the context of NG9-1-1 and recommend any changes to relevant NG9-1-1 documentation. Calls are Tuesday's at 11 am ET for 1 hour.
