+# OpenTelemetry .NET Diagnostic: OTEL1003
+
+## Overview
+
+This is an Experimental API diagnostic covering the following API:
+
+* `MetricStreamConfiguration.CardinalityLimit.get`
+* `MetricStreamConfiguration.CardinalityLimit.set`
+
+Experimental APIs may be changed or removed in the future.
+
+## Details
+
+The OpenTelemetry Specification defines the
+[cardinality limit](https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/metrics/sdk.md#cardinality-limits)
+of a metric can be set by the matching view.
+
+From the specification:
+
+> The cardinality limit for an aggregation is defined in one of three ways:
+> A view with criteria matching the instrument an aggregation is created for has
+> an aggregation_cardinality_limit value defined for the stream, that value
+> SHOULD be used. If there is no matching view, but the MetricReader defines a
+> default cardinality limit value based on the instrument an aggregation is
+> created for, that value SHOULD be used. If none of the previous values are
+> defined, the default value of 2000 SHOULD be used.
+
+We are exposing these APIs experimentally until the specification declares them
+stable.
