# Metadata data-set reference

The [Metaflow ](/docs/platform-description/mediaflow-services.md#metaflow)describes how the platform handles metadata. To get metadata from Audalaxy, use the [MetaSpreader](/docs/platform-description/networking-and-content-delivery.md#metaspreader). A metadata data-set contains the following data for each audio item:

```json
{
    "id": "ebbf8b04da405f51ad6aab607a7ffbe8",
    "channelname": "Radio Brocken Lovesongs",
    "channelshortname": "RB Lovesongs",
    "time": "2021-02-18T20:55:38Z",
    "duration": "227",
    "song": "Naked",
    "artist": "James Arthur",
    "channelkey": "fhl_rbroos7_klun3",
    "brandid": "radiobrocken",
    "cover": "https://cloudspace/cover.jpg",
    "separator": "-",
    "timezone": "UTC",
    "etype": 1001
