Also, Aggregation...
![Page 10: Sharing Content Through Syndication ACE/NETC June 2, 2005](https://reader035.vdocuments.mx/reader035/viewer/2022062304/56649d975503460f94a805f3/html5/thumbnails/10.jpg)
Aggregation
• Collect syndication feeds in one place
• Sort information by topic
• Re-syndicate information
• Searchable
• Archivable
![Page 11: Sharing Content Through Syndication ACE/NETC June 2, 2005](https://reader035.vdocuments.mx/reader035/viewer/2022062304/56649d975503460f94a805f3/html5/thumbnails/11.jpg)
So...
• Sharing content through syndication uses RSS and News aggregation to ‘push’ content directly to subscribers
• Syndication reaches new audiences and makes it easier for people who want the news you have to receive it

Two years ago...
• Most Extension news sites not dynamic
• No syndication feeds
• Need to aggregate topic sites (food safety) for critical information and efficiency

Factors
• Locally managed content
• Collaborative aggregation
• Alerts
• Multiple formats
• Standards-based tagging
• Local Contributions (anyone can contribute)

Tasks

Outcomes

Web Services
![Page 19: Sharing Content Through Syndication ACE/NETC June 2, 2005](https://reader035.vdocuments.mx/reader035/viewer/2022062304/56649d975503460f94a805f3/html5/thumbnails/19.jpg)
Provide a Web Service Interface
• Another way that you can retrieve dynamic news feeds built upon specialized query options.

Advantage
• Platform independent since we are using a SOAP (Simple Object Access Protocol)
