This tutorial explains the details on how to use Attribute Loader in Adobe Search and Promote.
Attribute loader help us to provide additional meta data to the URL’s crawled from website.
For example, the PDF’s document crawled from the website will not have any additional metadata specified but the additional metadata can be loaded through Attribute Loader.
e.g while crawling the pdf document from website it will be possible to provide only pdf URL and file name but will not be able to provide the additional details like title, description etc, these additional metadatas can be provided via Attribute Loader.
The values will be merged during indexing through primary key value.
