This deliverable, D23 — Dissemination, Promotion, Scientific Outreach and StandardisationReport v2.0 — provides a comprehensive, evidence-based account of the dissemination,communication, scientific outreach, and standardisation activities of the CODECO across itsfull project lifetime, M1 to M39 (January 2023 – March 2026). Building on the foundationestablished in D22, this report demonstrates the evolution of WP6 activities from initialvisibility-building in Phase 1 toward sustained community engagement, industrial integration,open-source ecosystem building, and active contributions to open standards in Phase 2.Across M1–M39, CODECO produced 38 unique peer-reviewed publications — 13 journalarticles, 20 conference and workshop papers, and 5 preprints — with 8 journals in Q1 SJR-ranked venues and 8 conference papers at ICORE A*-ranked venues, including IEEEINFOCOM (×5), AAAI, USENIX NSDI, and AAMAS. The CODECO Zenodo communityaccumulated over 2,247 unique views and 2,638 unique downloads across 76 total recordsencompassing publications, presentations, white papers, deliverables, and datasets.The project was represented at 68 events across 15 countries, significantly exceeding its KPIof 50, and delivered 26 talks and presentations to audiences spanning academic, industrial,standardisation, and public communities. CODECO partners held 18 TPC, steeringcommittee, and organising roles at major IEEE and ACM venues including IEEE INFOCOM,IEEE ICDCS, IEEE Globecom, and ACM MobiCom. The consortium organised its own flagshipevents — two editions of the ML4ECS workshop at HiPEAC 2025 and 2026 (jointly withMLSysOps and EDGELESS), the IETF 123 Hackathon, the CONASENSE 2025 Workshop,IRCEP Local Events, and the CODECO Final Event — collectively reaching several hundredparticipants from across the European and international research and industry communities.Standardisation activities delivered 16 documented contributions against a KPI of 10,including 5 IETF drafts submitted to the COINRG, ALTO, DetNet, GREEN, and BMWGworking groups; 2 ETSI contributions; 2 community white papers; 2 EUCEI OpenContinuumlandscape deliverables in which CODECO is featured; 1 NetWorld Europe SRIA contribution;and 2 AIOTI landscape reports featuring the project — one of which describes all six CODECOpilots in detail. CODECO's inclusion in the OpenContinuum D2.2 deliverable1 feeds into anemerging ISO/IEC JTC1 standardisation process for the CEI reference architecture. Twodedicated CODECO Standardisation Events were organised: the IETF 123 Hackathon inMadrid (July 2025) and the CODECO Standardisation Workshop 2026 (February 2026).Public dissemination reached 6,200 website visitors across the project lifetime — averagingover 2,000 per year against a KPI of 500 — and 662 LinkedIn followers, more than threetimes the KPI of 200. The CODECO Learning Hub, launched in Phase 2, provides fourcategories of educational resources (LEARN, WATCH, LISTEN, ACCESS) and will bemaintained for a minimum of five years post-project alongside the website, Zenodocommunity, and Eclipse GitLab open-source repository.The IRCEP programme structured external engagement through challenge-basedcompetitions, with Best Talk awards distributed at the HiPEAC 2025 ML4ECS workshop,CONASENSE 2025, and with IRCEP Challenges engaging students and early-careerresearchers across Europe.Collaborative engagement with EUCEI, AIOTI, BDVA, HiPEAC, MLSysOps, EDGELESS,NEMO, CyberNEMO, and five further Horizon Europe projects produced a joint white paper,three co-authored publications, two co-organised workshop series, and sustained communityalignment that positions CODECO's outputs as lasting contributions to the European CEIresearch ecosystem.
