# Updating External Version Metadata

## Updating Metadata

[CLDR\-15005](https://unicode-org.atlassian.net/browse/CLDR-15005) is for updating the process for external metadata versions. The following table is out of date with [common/properties/external\_data\_versions.tsv](https://github.com/unicode-org/cldr/blob/main/common/properties/external_data_versions.tsv)

### TODO: Need to add instructions for updating external metadata
