+    Implement to fetch the state effecter PDRs. PDRs are Platform Descriptor
+    Records which are the collection of information that includes semantic
+    and association information. The state effecter PDR is used to provide
+    information about the PLDM Composite State Effecter.
+
+    This API would be used by PLDM Requester apps on the BMC.
+
+    An implementation of this interface should maintain the primary PDR
+    repository on the BMC.
+
+    A OpenBMC implementation should implement the xyz.openbmc_project.PLDM.PDR
+    interface on the path /xyz/openbmc_project/pldm.
+
+    More information about PDR can be found at DSP0248 version 1.2.0 section 25.
