Linked data
Linked data is a method for publishing structured data on the Internet, allowing disparate datasets to be connected and accessed in a meaningful way. Proposed by Tim Berners-Lee, known as the inventor of the Internet, linked data enables the creation of a linked open data cloud, where users can search for and compare related datasets. The architecture relies on HTTP protocols and utilizes Uniform Resource Identifiers (URIs) to identify and categorize digital resources. Berners-Lee's four principles emphasize the importance of linking data through URIs, providing useful information via RDF (Resource Description Framework) and SPARQL (a query language for RDF), and interconnecting different datasets through links.
Although primarily designed for machine interpretation, humans interact with linked data through specialized software, making it easier to navigate interconnected datasets. Widely recognized linked open data platforms include Wikidata, Geonames, and DBpedia. The concept of linked data underpins the Semantic Web, a vision for a more interconnected and accessible Internet where data can be efficiently refined and utilized. This framework highlights the growing importance of structured and accessible data in driving modern technological advancements.

Linked data
Linked data is a means by which Internet databases publish structured data. It was recommended by Tim Berners-Lee, a famed computer scientist best known as the inventor of the Internet. When numerous datasets are linked together, they form a linked open data cloud. This allows computer users to search, find, and compare related datasets.
Linked data sets are organized through HTTP protocols in a manner similar to the modern Internet. However, they are designed to be reviewed and interpreted by machines and programs. Humans interact with the data through these programs.
Overview
Linked data is a method for publishing structured data. It allows for statements and data to be displayed across several websites. It also allows for structured data to be interpreted by machines in an effective, reliable manner.
According to the principle of linked data, the more sets of data that the Internet can link together, the more powerful the Internet will grow. To maximize the amount of data collectively linked by the Internet, Berners-Lee created four design principles of linked data in 2006. These principles are widely followed by the modern Internet.
His first rule dictates that web designers and programmers should use the Uniform Resources Identifier (URI) as the primary global identification system for the Internet. This means that anything discussed or made available on the Internet, including both research and media, should be categorized through the use of the URI.
To maximize the usefulness of URI, Berners-Lee declared that URIs should be organized according to HTTP protocols. HTTP protocols are a simple mechanism for organizing and retrieving resources. When digital files can be identified by their URI and retrieved via HTTP, they are easier for users to find and access.
Berners-Lee’s third rule states that useful information through RDF or SPARQL standards should be provided whenever someone looks up a URI. RDF is a graph-based representation format designed for publishing data. It allows people to efficiently store interconnected data. SPARQL is a standardized query language designed to interact with RDF. It allows users to search RDF databases, interact with data, and discover relationships between datasets.
Berners-Lee’s fourth rule encourages the inclusion of links to other URIs within existing URIs. This creates a large, interconnected network that can be processed by both machines and individuals. Interlinking new information with existing resources increases the size of the network, helping more people discover related and helpful information.
In most cases, humans do not directly interact with linked data. Though the format uses Internet technologies that are commonly utilized directly, such as HTTP and URIs, the format is best suited to being read by machines. However, human users typically use specialized software to interact with and query datasets organized in a linked data format.
Large numbers of datasets that are linked together form a linked open data cloud. When connected with a user-friendly navigational interface, this allows computer users to travel from single datasets to many related datasets within the same network. Commonly utilized linked open data clouds include Wikidata, Geonames, and DBpedia.
Data has drawn comparisons to petroleum as the fuel that drives the modern world. Nonetheless, data must be accessible to be employed. This accessibility is made possible by having data structured along commonly accepted standards, principles, and technology. The term used for the outcome of this sequence is the “Semantic Web.” This contrasts with the original internet, or World Wide Web, which in many ways was a collection of unstandardized, stand-alone web documents. The Semantic Web is enabled through linked data. A Semantic Web will treat data as a raw material where it can be accessed and refined into a finished product. A Semantic Web is how many describe the future enabling characteristics of linked data.
