 In this episode, Lynn Foster—champion of open-source software and co-author of the Value Flows vocabulary—shares her journey from corporate software development to creating commons-based economic infrastructures. She explains how Value Flows provides a shared language for representing economic activity, enabling projects and organizations to coordinate without relying on siloed systems. At the heart of this work is REA accounting (Resources, Events, Agents), an elegant model that traces real-world flows of resources and interactions across networks.Foster explains how Value Flows and REA accounting enable interoperability across distributed systems and why ontologies, that is shared vocabularies are critical for both people and software to communicate effectively. She also reflects on the real-world impact of projects such as cooperative supply chains and regenerative networks.Lynn Foster explores:Code vs. Community – How open-source software becomes powerful when a community organizes around it.From ERP to REA – Why flow-based accounting creates clarity across networks and ecosystems.Networks of Networks – The potential of Value Flows and Holochain integration to connect grassroots initiatives.Watch this episode on YouTubeListen to this episode:Apple Podcasts • Spotify • Pocket Casts • RSS FeedThemes:Open Source as Commons – How shared vocabularies and cooperative communities make technology durable.Ontologies & Interoperability – Why common data meanings allow software ecosystems to plug and play.Flow-Based Accounting (REA/Value Flows) – Moving beyond double-entry into transparent, cross-network flows.Distributed Architectures – What makes Holochain different and better suited for decentralized collaboration.Regenerative Supply Chains – Lessons from the Carbon Farm Network and other next-economy experiments.Contribution Economies – Models that reward contributions fairly and support resilience.Timestamps:Origins & Foundations00:00 — Opening reflections on open source as a growing seed01:53 — Lynn’s background and introduction to Value Flows & hREA03:07 — Leaving corporate software to build economic commons04:35 — First “aha moment” in open source: a stranger contributes a logo05:08 — The difference between open source code and open source communityValue Flows & Ontologies06:20 — The Open App Ecosystem: modular tools like Lego blocks06:52 — Why vocabularies are needed for interoperability07:40 — APIs vs. shared vocabularies: simplifying collaboration08:17 — Ten years of Value Flows: what has evolvedPatterns & Flows08:40 — Conway’s Law: communication shapes technology10:30 — Supply chains and the shift from “best company” to “best supply chain”11:16 — Trust and transparency across enterprises12:20 — Expanding the surface of cooperation rather than competingREA & Network Resource Planning13:50 — REA explained: Resources, Events, Agents15:35 — Three layers: policy, planning, and observation16:55 — Directed graphs: tracing resource provenance and flows18:10 — From ERP’s silos to NRP’s networks19:30 — Working with Sensorica on open hardware and contribution accountingOntologies in Practice21:09 — What ontologies are and why they matter22:53 — Shared meaning for humans and software alike24:28 — Configurability and taxonomies: flexibility without lock-in26:54 — Digital Product Passports in the EU as a use caseDistributed Systems & Carbon Farm Network27:58 — What makes Holochain unique: no central servers29:35 — Using Value Flows to connect Holochain networks31:30 — hREA as a generic backend for many user experiences31:55 — Case study: the Carbon Farm Network in New York33:21 — Supporting sustainability and local supply chains34:46 — Challenges: funding cuts, infrastructure closures, systemic inequality36:30 — Possibilities for cooperative ownership of spinning millsBroader Applications & Future Directions38:45 — Offers/Needs apps, mutual credit, barter, and gift economies40:58 — Contribution economies and benefit distribution algorithms42:10 — EU projects: Reflow, Fab City, and The Weathermakers43:50 — Expanding agents/resources to rivers, forests, carbon, nitrogen45:46 — Regional planning and resilience after crises47:28 — Building relationships now for resilience in uncertain futures49:41 — Small pieces of the puzzle: upward spirals of collaboration51:00 — Closing reflections on the importance of collective effortReferences:REA Accounting Model – Bill McCarthyValue Flows Vocabulary – Co-created by Lynn Foster, Bob Haugen, and collaboratorsDigital Product Passports (EU Initiative) – Ongoing regulatory frameworkSensorica – Open value network experiments in contribution accountingTranscriptLynn Foster (00:00.076)I think open source is one of these seeds that's kind of growing within the beast, so to speak, where it organically appears and it wants to be born.
