Source string usage details

You can create as many Feeds importer configurations as you would like to. Each can have a distinct purpose like letting your users aggregate RSS feeds or importing a CSV file for content migration. Here are a couple of things that are important to understand in order to get started with Feeds:

• Every importer configuration consists of basic settings, a fetcher, a parser and a processor and their settings.
• The basic settings define the general behavior of the importer. Fetchers are responsible for loading data, parsers for organizing it and processors for "doing stuff" with it, usually storing it.
• In Basic settings, you can attach an importer configuration to a content type. This is useful when many imports of a kind should be created, for example in an RSS aggregation scenario. If you don't attach a configuration to a content type, you can use it on the !import page.
• Imports can be scheduled periodically - see the periodic import select box in the Basic settings.
• Processors can have mappings in addition to settings. Mappings allow you to define what elements of a data feed should be mapped to what content fields on a granular level. For instance, you can specify that a feed item's author should be mapped to a node's body.
