The present document defines the metadata for Performance Management (PM) performance measurements (KPIs/counters). The definition would enforce consistency in description/definition of all standardized performance measurements (counters/KPIs) by various SDOs and organizations (or Multi-SDO) involved in the Management of Converged Networks . This consistency would facilitate encoding and decoding of performance measurements (counters/KPIs) exchanged (via management protocols) and/or stored in (database or files).
The metadata related to PM operations/notifications is not part of this PM measurement metadata.
The present document takes into account the recommendations from the Fixed Mobile Convergence (FMC) model repertoire  developed by the Multi-SDO JWG on Model Alignment.
