Table #4: Breaking Down Silos – Data Interoperability Across Government Agencies

Monday, March 23 | 2:00 pm-3:00 pm | Expo Hall

Does your planning department share its parcel data with the water department? Do your emergency responders work from the same address list as your permitting office? In most cities and counties, the answer is no. Different agencies maintain their own versions of the same foundational datasets, often in incompatible formats, with no easy way to connect them.
This results in duplicated spending, slower service delivery, and decisions made on incomplete information.
Join this roundtable for an open conversation about what it would take to bridge the divide across agencies within a single government, across neighboring jurisdictions, and between the public and private sectors.

Speaker
Dana Bauer, Technical Product Manager, Overture Maps Foundation

A New Public-Private Model for Digital Infrastructure: How Open, Interoperable Base Maps Accelerate Project Delivery
Wednesday, March 25 | 11:15 a.m.–12:00 p.m. | Dallas BC
Government agencies make high-stakes decisions every day about safety investments, road expansions, permitting, resilience, and long-term capital planning. Too often, those decisions rely on fragmented, inconsistent, or outdated geospatial data. At the same time, private sector companies are building rich, highly accurate open map data to power services in mobility, logistics, and local search.
Founded by Amazon Web Services, Meta, Microsoft, and TomTom, the Overture Maps Foundation is creating open, high-quality, interoperable base map data that anyone can use. By harmonizing inputs from public and private contributors, standardizing schema, and providing a common reference system (GERS), Overture enables agencies, vendors, and researchers to work from the same trusted foundation. The result is less duplication, stronger interoperability, and faster project delivery.
This panel will explore how municipalities are already using Overture data for emergency response, transportation planning, economic development, and permit management. Speakers will highlight Fresno County’s implementation, explain how GERS improves consistency across data sources, and share practical approaches for integrating continuously updated map data into government workflows.

The Overture Maps Foundation is headed to Open Source in Finance Forum Toronto 2026 to join leaders from across financial services, technology, and open source.
Building the Open Data Commons: Why Finance Needs a Shared Entity Graph
Tuesday, April 14 | 5:25 p.m.–6:00 p.m. EDT | Ballroom East
Financial services depend on foundational business data such as company information, legal entities, ownership structures, locations, and relationships. Yet this data remains fragmented, inconsistently defined, and costly to reconcile.
This panel introduces a new Open Data Consortium under The Linux Foundation to address these challenges through shared governance, open standards, and collaboratively maintained datasets.
The consortium focuses on building an open global entity graph, a structured dataset linking organizations, legal entities, locations, and people. Sourced from verified public records, this resource supports Know Your Business (KYB), Know Your Customer (KYC), anti money laundering (AML), risk management, and artificial intelligence workflows.
Panelists will explore how to build and sustain this shared asset, including data definitions, standards development, governance models, and balancing openness, privacy, and commercial participation. The discussion will also highlight community formation and ecosystem design.
For financial institutions, regulators, fintech companies, and open source leaders, this session offers an opportunity to engage early in shaping shared data infrastructure.
