The SDS Audio player presents can present both audio files and playlists of audio files. The two cases have slightly different display rules. Playlists are discussed first in this document.
What do we mean by 'playlist'?
A playlist is an XML file that contains descriptive and structural metadata about streaming audio delivered from DRS. Streaming audio represented by an audio playlist can contain one or more audio files or/and one or more segments from the same audio file.The XML files use the AES-60 specification and are deposited in the DRS as part of Text Objects. There is more information on creating and depositing playlists in the Creating Text Objects section of the DRS BatchBuilder Guide

SDS playlist information in track listings section
As described in the “Create and deposit audio playlists as text objects” page in the Batch Builder Guide, information for each individual track is stored in <part> ... </part> sections in the AES-60 file.
| SDS track listings and audio controls | SDS Current track information in Metadata Pane |
 |  |
AES-60 defined elements that are available for display in the SDS track listing:
- Title
- Creator
- Contributor
Other AES-60 defined elements that are not currently available for display in the SDS track listing:
- Description
- Date
- Rights
AES-60 defined elements that provide information for Audio playback
- Identifier - URN of audio file to play for a particular track
- Format - Contains start time in audio track and duration
Things to note about information in the SDS Track listings section:
- Creator and Contributor can be used multiple times per track with different data
- Creator and Contributor elements can be qualified with Role type labels
- Creator and Contributor information is displayed immediately after the title in a track listing.
- Role type labels for Creators and Contributors appear before actual names with an added colon – like ‘Author:’
- There is a break between each track in the listing, and each track listing has a background color slightly darker than the overall background
Each track in the AES-60 file (‘part’ element) is displayed in the track listing in this order without any line breaks:
[Title information] [Creator Role type label (if present):] [Creator Name]; [additional creators]; [Contributor Role type label (if present):] [Contributor Name]; [additional contributors] |

 | <part><title><dc:title>1. <-- that number is a part of the title. There is no automatic numbering of the tracks. Also, you can include HTML references in the titles, but you have to encode them.
