# Metadata

A metadata field name and value that specifies the reference images to compare the ingested image to.

You can also set Database and Identifier. Media Server only compares the ingested media to reference images that match all of the specified criteria.

The field name and value are case-insensitive.

Separate the field name and value with a colon. To include a colon in the key name or value, enclose the key name or value in quotation marks (`"`) and escape any quotation marks that occur within the string with a backslash (`\`).
