Runtime, number of tracks and map scales

To inform customers – similarly to file size – which extent a playable product has, you can provide data on its runtime. While runtime data should be provided for all audio and video products, the number of tracks is of interest primarily for audio products. The track number specifies how many titles a CD or download product (e.g. an mp3 compilation) contains. The track number should be provided to supplement the runtime.

• Runtime
• Number of tracks

• Map scale

The runtime is expressed in the extent composite using code 09 for the ExtentType or b218. The unit used for the runtime is listed in ExtentUnit or b220. The following values from code list 24 can be used here.

A product with a 60-minute runtime will be displayed as follows.

<extent>
 <b218>09</b218> 
 <b219>60</b219>
 <b220>05</b220> 
</extent>

<Extent>
 <ExtentType>09</ExtentType>
 <ExtentValue>60</ExtentValue>
 <ExtentUnit>05</ExtentUnit>
</Extent>

The number of tracks is expressed in the extent composite using code 09 for the ExtentType or b218. In ExtentUnit or b220, only one unit is permissible.

A product containing 18 tracks is to be entered as follows.

<extent>
 <b218>09</b218> 
 <b219>18</b219>
 <b220>11</b220> 
</extent>

<Extent>
 <ExtentType>09</ExtentType>
 <ExtentValue>18</ExtentValue>
 <ExtentUnit>11</ExtentUnit>
</Extent>

The map scale is to be specified as 1: n. In ONIX, only the value for n is stored, which must be a number.

A map scale of 1:20,000 is to be entered as follows.

<b063>20000</b063>

<MapScale>200000</MapScale>
