Towards Interoperable Anchoring for XR

As a part of the Metaverse Requirements Discussion board’s Particular SDO Classes, the Discussion board performed the In direction of Interoperable Anchoring for XR webinar on April 30, 2025. The webinar centered on efforts to attain interoperable anchoring programs for prolonged actuality (XR). The principle presenters, Jérémy Lacoche (Orange) and Jérôme Royan (BCOM), shared work from ETSI’s Augmented Actuality Framework (ARF), highlighting new requirements, structure, and open-source instruments designed to allow constant AR experiences throughout platforms and units.

Neil Trevett, President of the Metaverse Requirements Discussion board, opened with an outline of the Discussion board’s mission: to foster cross-silo cooperation and assist pragmatic, bottom-up standardization efforts throughout metaverse applied sciences, together with AI, XR, Web3, and digital twins.

The core subject addressed was the shortage of a shared, standardized strategy to signify the actual world in XR. In the present day’s AR programs usually depend on ecosystem-specific spatial anchors and monitoring applied sciences, limiting cross-platform compatibility. ETSI’s ARF proposes a unified mannequin for representing the actual world utilizing a graph-based construction referred to as a “world graph.” This integrates a number of varieties of trackables (e.g., picture markers, 3D maps, geolocation knowledge) right into a spatially-organized, interoperable reference system. By separating the real-world mannequin (world graph) from digital content material (scene graph), purposes can share environments and belongings extra flexibly.

Open-source instruments had been additionally offered, together with Unity-based editors, world evaluation modules (for pose estimation), and distant server implementations. Demos illustrated industrial upkeep use instances utilizing a mixture of indoor and out of doors localization applied sciences throughout each iOS and Android.

The webinar concluded with Q&A, highlighting the necessity for constant coordinate programs, curiosity in semantic integration (ontologies), and discussions on collaboration with requirements teams like Khronos and OpenXR. ETSI’s ongoing work goals to increase assist for geometry, look, and semantics, enabling richer real-world interactions and simpler AR content material creation at scale.
