+## About this Extension
+This extension creates a Policy Definition `always-true` on EDC startup.
+
+## Why does this extension exist?
+
+While the default behavior for contract definitions with empty policies is not "default deny",
+our UI will be ensuring non-empty access and contract policies.
+
+Therefore, it is of interest to have an `always-true` policy to explicitly enable full access in contract definitions.

+## About this Extension
+
+This extension adds a policy function that validates the time of data consumption.
+
+Adds permission function with left side expression `POLICY_EVALUATION_TIME` and supported
+operators `EQ`, `NEQ`, `LT`, `LEQ`, `GT`, `GEQ`. The right side expression is expected to be in the following date
+format `yyyy-MM-dd'T'HH:mm:ss.SSSXXX`.
+
+## Why does this extension exist?
+
+Limiting data offers to specific valid durations.
