Mashing SharePoint RSS with Presto

 The screenshot below shows the example SharePoint Team Discussion List which we will publish in Presto as an RSS Feed. The List can be viewed in the form of an RSS Feed by selecting Actions -> View Feed. The RSS Feed URL identifies the GUID associated with this SharePoint List.

Before publishing the SharePoint RSS Feed to Presto we need to gather the following information, assuming we have a SharePoint Site named Jackbe :

1. A name to uniquely identify the published Presto Service, eg. SpJackbeDiscussion, signifying Sharepoint Service, Jackbe Site, Discussion List.
2. The URL for the RSS Feed, eg. http://www.mycompany.com/sites/Jackbe/_layouts/listfeed.aspx?List={GUID}, where GUID is the Id asscoaited with the RSS Feed.
3. NT Lan Manager (NTLM) Username, password and domain.

Using Presto ServiceExplorer, we launch the RSS/ATOM publishing wizard and enter our details, select NTLM authentication and enter our user credentials. The screenshot below shows an example of the Service details entered in the Service Explorer Publishing Wizard.

Presto will access the service, read and validate the feed and prepare the Service as a Presto Published Service. If successful, the wizard will stop to allow us to configure role based access to the service as a whole and/or to individual getFeed operation.

Having published the service, by default the service will be activated and ready to be invoked, we are now ready to use the service as a Mashable in Wires.
