+# GraphQL Nodes - Global Object Identification
+
+To provide options for GraphQL clients to elegantly handle caching and data refetching, GraphQL servers need to expose object identifiers in a standardized way.
+
+For this to work, a client will need to query via a standard mechanism to request an object by ID. Then, in the response, the schema will need to provide a standard way of providing these IDs.
+
+Example
+```graphql
+{
+  node(uid: "MTM0MzQ=") {
+    id
+    ... on SimpleProduct {
+      name
+      uid
+    }
+    ... on CategoryTree {
+      name
+      children
+    }
+  }
+}
+```
+
+Nodes IDs should be unique throughout the entire schema and ideally for every store since store code is unique
+
+To implement this the uid has to be composed out of:
+```
+base64Encode("StoreCode/__typeName/id")
+```
+
+This way we can know what is the type requested and render it to the actual type.
+It will help our schema to be more compliant as all entities should be nodes.
