DatumSourceMetadataClearCache topic

This instruction asks a node to remove any cached datum metadata for a set if source IDs, so the node is forced to reload that metadata from SolarNetwork. Nodes cache datum metadata so they do not need to repeatedly load it from SolarNetwork. After you update metadata, you can issue this instruction to get the node to pick up the changes.
