-Regardless of where it comes from, every record in VuFind is represented by a [[development:plugins:record_drivers|record driver object]].  Like the search objects, all record drivers inherit from a common base class that implements basic record-related behavior (saving to favorites, adding tags, etc.).  However, subclasses have a great deal of flexibility in how they represent records.  Each record driver gets its own set of templates for rendering within the VuFind interface, so displays can be completely customized.  However, by implementing a [[vufind2:record_driver_method_master_list|standard set of get methods]] for retrieving common sorts of data elements (title, author, subject, etc.) it is possible to share templates between similar record drivers for less complex code and a more consistent user experience.+Regardless of where it comes from, every record in VuFind is represented by a [[development:plugins:record_drivers|record driver object]].  Like the search objects, all record drivers inherit from a common base class that implements basic record-related behavior (saving to favorites, adding tags, etc.).  However, subclasses have a great deal of flexibility in how they represent records.  Each record driver gets its own set of templates for rendering within the VuFind interface, so displays can be completely customized.  However, by implementing a [[development:architecture:record_driver_method_master_list|standard set of get methods]] for retrieving common sorts of data elements (title, author, subject, etc.) it is possible to share templates between similar record drivers for less complex code and a more consistent user experience.
