Appendix B Creating Manifest Files

Working with Manifest Files

If the expires attribute is specified inside an <item> tag, it applies to that item; if it is specified inside a

<crawler> tag, the attribute applies to the crawl job.

You can monitor the status of content replication and freshness by enabling and then viewing the

transaction log files that reside on the Service Engines. To verify whether or not a content object or file

was successfully imported to or refreshed on a particular Service Engine, take these actions:

• Enable the transaction log function on the Service Engine you want to monitor.

• View the transaction log entries for the content object or filename that resides on that Service

Engine.

Specifying Live Content

Only Windows Media live contents can be specified in the Manifest file. Use the <item> tag and specify

the type attribute as wmt-live, as shown in the following example. The live stream for the wmt-live

content type is url=rtsp://www.company-web-site.org/tmp/ceo-talk.

</server>

</item>

<!--

This is a "wmt-live" streaming content type specified by the "type" attribute. The live

stream URL is

rtsp://www.company-web-site.org/tmp/ceo-talk.

-->

</CdnManifest>

Specifying Hybrid Ingest Content

For hybrid ingested content, the content is not prefetched into the CDS network. Instead, the content is

ingested dynamically based on the user request. This type of ingest is called dynamic ingest or

on-demand ingest. In order to control the play back of the on-demand content, a new type of ingest has

been introduced called hybrid ingest. In this method, the metadata for on-demand contents can be

specified in the Manifest file. However, the actual content is not acquired by the Content Acquirer.

Hybrid ingest is supported by specifying “cache” as the value for the type attribute inside the <item> tag.

Note This mode of ingest is supported only for single items; crawling is not supported.

Following is an example of a Manifest file for hybrid ingest content:

</server>

<item src="/tmp/ceo-talk.wmv" type="cache"

serveStartTime="2007-01-12 14:00:00 PST"

serveStopTime="2007-04-12 14:00:00 PST"

</item>

</CdnManifest>
