An Introduction to Linked Data

Decomposing Liked Data , we got liked and then another word Data .So, come up with Linked . What does it mean linked , ah! Interesting but not new to us.

Back to our teenage .

A boy named Goni is linked with a girl name Ulfot by mysterious glue love . So link means connection and liked means a virtual connectivity between two thing/object/a boy – a girl. Formally or as a eye of computing student we can define it as a association or associativity . Lets back to the love relation between Goni and Ulfot . Hear Goni and Ulfot are two object and they are related with a property named love .

Now, second word data .Data means a abstract concept. In computing world personally I prefer to use word raw before the trivial concept data.

Linked + Data = Linked Data

It's really simple to understand what implication made by the combination of liked and data .As, some associated data liked with some property middle of them . If Goni and Ulfot are two data object and love is a property between them. Then a virtual visualization come up inside our mind it is nothing but a liked data structure as mentioned by a formal computing science student.

Lets : run through the planet named web then we got strong and must mentioned relationship with world wide web (www) and linked data. Web is all about data and information (organized data known as information).In recent days web is also know as data web. Data web or web of data whatever we call this abstract concept there is another name of this concept is known as semantic web .Ah! Hear we go linked data is the backbone of semantic data.

But all of those data are not organized or structured and manageability and usability of those raw data are quit difficult and in some case that are almost impossible,because of the less structured or not organized at all and another parameter is the mammoth size of the data and it is increasing rapidly in every single second where stack holder is like a tiny toy. So ,we need to organize those data formally and in standard way.

So...

Linked Data is about using the Web to connect related data that wasn't previously linked, or using the Web to lower the barriers to linking data currently linked using other methods. More specifically, Wikipedia defines Linked Data as "a term used to describe a recommended best practice for exposing, sharing, and connecting pieces of data, information, and knowledge on the Semantic Web using URIs and RDF." (ref : http://linkeddata.org/)

Example :

A typical case of a large Linked Dataset is DBPedia, which, essentially, makes the content of Wikipedia available in RDF
