RDF and Semantic Web

Data is growing day by day exponentially and in future it will grown even with much more faster pace. To handle this huge amount of data in the current scenario using a SQL database will be cumbersome, time taking and very very difficult to manage the complex relationships.

Now what is RDF. Well, it stands for Resource Description Framework. As the name suggests, it is all about describing the information about data or in other words metadata of the data.
To give an example the name, size, author, location, associated objects, etc.

It is a new way of dealing with the information about data as opposite to the conventional tabular format. This is part of the Semantic Web defined by W3C. It is defined in a format so that it can be easily understood by the computers and is written in XML format. The information is defined in the form of the triples.

RDF Example:

<?xml version=”1.0″?>

<RDF>
<Description about=”http://www.fondofit.com”>
<author>Laxmi</author>
</Description>
</RDF>

It describes about the resource http://www.fondofit.com and correspond to the following statement:

“Laxmi is author of FondOfIt.com”

This is just an example of RDF Statement.  We will get to know about RDF Statement in next article.

  1. 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.
