+# OMI_ref
+
+## Contributors
+
+* Robert Long, Element Inc.
+
+## Status
+
+Open Metaverse Interoperability Group Stage 1 Proposal
+
+## Dependencies
+
+Written against the glTF 2.0 spec.
+
+## Overview
+
+This extension allows a glTF document to reference resources in other glTF documents. This enables better resource sharing between assets, streaming / progressive enhancement, and authoring use-cases.
+
+### Example:
+
+Root File:
+
+```json
+{
+  "scenes": [
+    {
+      "name": "Default Scene",
+      "nodes": [0]
+    }
+  ],
+  "nodes": [
+    {
+      "name": "Duck",
+      "translation": [1.0, 2.0, 3.0],
+      "extensions": {
+        "OMI_ref": {
+          "uri": "asset.glb",
+          "scene": 0
+        }
+      }
+    }
+  ]
+}
+```
+
+Referenced File (asset.glb):
+
+```json
+{
+  "scenes": [
+    {
+      "name": "Duck",
+      "nodes": [0]
+    }
+  ],
+  "nodes": [
+    {
+      "mesh": 0
+    }
+  ]
+}
+```
