Importing and synchronizing content using Feeds
•

This document discusses how to use the Feeds module in Drupal to import and synchronize content from various sources. Feeds allows importing content like nodes, users, taxonomy from RSS, CSV, XML and JSON feeds. It provides fetchers to access remote sources, parsers to interpret different formats, and processors to save content as Drupal entities. Examples demonstrated include importing Flickr photos and keeping RSS feeds in sync. The document also covers using Feeds with Commerce products, tampering to modify field values, and enabling real-time updates via PubSubHubbub.
