21⟩ Why RDF is designed?
RDF was designed to provide a common way to describe information so it can be read and understood by computer applications.
RDF descriptions are not designed to be displayed on the web.
“RDF Interview Questions and Answers will guide us now that Resource Description Framework (RDF) is a family of World Wide Web Consortium (W3C). RDF has come to be used as a general method for conceptual description or modeling of information that is implemented in web resources, using a variety of syntax formats. So learn about Resource Description Framework with the help of this RDF Interview Questions with Answers guide”

he Semantic Web is about a web of data. The data itself can reside in databases, spreadsheets, Wiki pages, or indeed traditional web pages. The challenge is to develop tools that can export these data into RDF form: RDF plays the role of a common model, as a kind of a glue to integrate the data. That does not mean that the data must be physically converted into RDF form and stored in, say, RDF/XML. Instead, automatic procedures, for example SQL to RDF converters for relational databases, GRDDL processors for XHTML files with microformats, RDFa, etc, can produce RDF data on-the-fly as an answer to, eg, queries.
Both formalisms have their strengths and weaknesses; their area of usage is different. The two data models serve different constituencies and the choice really depends on the application. There is no better or worse; only different.
RDF Schema (Resource Description Framework Schema, variously abbreviated as RDFS, RDF(S), RDF-S, or RDF/S) is a set of classes with certain properties using the RDF extensible knowledge representation data model, providing basic elements for the description of ontologies, otherwise called RDF vocabularies, intended to structure RDF resources. These resources can be saved in a triplestore to reach them with the query language SPARQL.
RDF is a standard model for data interchange on the Web. RDF has features that facilitate data merging even if the underlying schemas differ, and it specifically supports the evolution of schemas over time without requiring all the data consumers to be changed.
