* first draft remediation of CIP-0010

* spelled NA instead of standard N/A

* revert accidental change intended for concurrent cardano-foundation#730

* fixing spurious change, perhaps from upstream merge

 Cardano transaction metadata forces metadata entries to namespace their content using an unsigned integer key. This specification is a registry of which use cases has allocated which number to avoid collisions.
 
-## Terminology
+## Motivation: why is this CIP necessary?
+
+The top level of the transaction metadata CBOR object is a mapping of `transaction_metadatum_label` to the actual metadata where the `transaction_metadatum_label` represents an (ideally unique) key for a metadata use case. This allows enables the following:
+
+1) Fast lookup for nodes to query all transactions containing metadata that uses a specific key
+2) Allows a single transaction to include multiple metadata entries for different standards
+
+## Specification
+
+### Terminology
 
 Transaction metadata refers to an optional CBOR object in every transaction since the start of the Shelley era. It is defined as the follow CDDL data structure

+## Path to Active
+
+### Acceptance Criteria
+
+- [x] Consistent, long-term use by Cardano implementors of the metadata label registry by all applications requiring a universally acknowledged metadata label.
+- [x] Consistent, long-term use in the CIP editing process: tagging, verifying, and merging new label requirements.
+
+### Implementation Plan
+
+- [x] Confirmed interest and cooperation in this metadata labelling standard and its `registry.json` convention by Cardano implementors: including NFT creators, data aggregators, and sidechains.
