Definition: This file handles RDF (Resource Description Framework) data, often used in web scraping. The "AboutProductsAndServices.rdf.widoco.conf" line is a configuration file that specifies what types of objects can be included in the RDF files. For example, it might include product details, services, etc. The file provides a list of allowed classes to include in each document type and allows for customizations such as schema versioning or additional fields. The file does not specify how to access or modify data in these documents, so if you need that information you would usually find the `about:config` section.
