Access Live RSS Feeds in TIBCO Data Virtualization

TIBCO Data Virtualization (TDV) is an enterprise data virtualization solution that orchestrates access to multiple and varied data sources. When paired with the CData TIBCO DV Adapter for RSS, you get federated access to live RSS feeds directly within TIBCO Data Virtualization. This article walks through deploying an adapter and creating a new data source based on RSS.

With built-in optimized data processing, the CData TIBCO DV Adapter offers unmatched performance for interacting with live RSS feeds. When you issue complex SQL queries to RSS, the adapter pushes supported SQL operations, like filters and aggregations, directly to RSS. Its built-in dynamic metadata querying allows you to work with and analyze RSS feeds using native data types.

Deploy the RSS TIBCO DV Adapter

1. In a console, navigate to the bin folder in the TDV Server installation directory. If there is a current version of the adapter installed, you will need to undeploy it.

   .\server_util.bat -server localhost -user admin -password ******** -undeploy -version 1 -name RSS
   

2. Extract the CData TIBCO DV Adapter to a local folder and deploy the JAR file (tdv.rss.jar) to the server from the extract location.

   .\server_util.bat -server localhost -user admin -password ******** -deploy -package /PATH/TO/tdv.rss.jar
   

You may need to restart the server to ensure the new JAR file is loaded properly, which can be accomplished by running the composite.bat script located at: C:\Program Files\TIBCO\TDV Server <version>\bin. Note that reauthenticating to the TDV Studio is required after restarting the server.

Sample Restart Call

.\composite.bat monitor restart

Create a RSS Data Source in TDV Studio

With the CData TIBCO DV Adapter for RSS, you can easily create a data source for RSS and introspect the data source to add resources to TDV.

Create the Data Source

1. Right-click on the folder you wish to add the data source to and select New -> New Data Source.
2. Scroll until you find the adapter (e.g. RSS) and click Next.
3. Name the data source (e.g. CData RSS Source).

4. Fill in the required connection properties.

   You can connect to RSS and Atom feeds, as well as feeds with custom extensions. To connect to a feed, set the URL property. You can also access secure feeds. A variety of authentication mechanisms are supported. See the help documentation for details.

5. Click Create & Close.

Introspect the Data Source

Once the data source is created, you can introspect the data source by right-clicking and selecting Open. In the dashboard, click Add/Remove Resources and select the Tables, Views, and Stored Procedures to include as part of the data source. Click Next and Finish to add the selected RSS tables, views, and stored procedures as resources.

After creating and introspecting the data source, you are ready to work with RSS feeds in TIBCO Data Virtualization just like you would any other relational data source. You can create views, query using SQL, publish the data source, and more.
