Linked Data - The Story So Far

Abstract

The term Linked Data refers to a set of best practices for publishing and connecting structured data on the Web. These best practices have been adopted by an increasing number of data providers over the last three years, leading to the creation of a global data space containing billions of assertions -the Web of Data. In this article we present the concept and technical principles of Linked Data, and situate these within the broader context of related technological developments. We describe progress to date in publishing Linked Data on the Web, review applications that have been developed to exploit the Web of Data, and map out a research agenda for the Linked Data community as it moves forward.

Ewya: An Interoperable Fog Computing Infrastructure with RDF Stream Processing

“…As previously noted, interoperability is an important metric for Eywa. To provide for interoperability, we consider Linked Data, a means of publishing data on the Web so that distributed structured data can be interconnected, exchanged and retrieved through semantic queries [5]. A common way of representing Linked Data is with the Resource Description Format (RDF) where the use and referencing of common identifiers and ontologies helps to integrate data.…”

“…This mapping references various ontologies like the Semantic Sensor Network (SSN) Ontology 4 and City Traffic Ontology, providing a common way of describing sensor data, increasing interoperability. A formal definition of the mapping language is covered in our previous paper [16] and as a specification 5 .…”

Role of Semantic Web in the Changing Context of Enterprise Collaboration

“…Linked data, a sub-topic of the Semantic Web, is basically about exposing, sharing and connecting data via URI (Uniform Resource Identifiers) and HTTP (HyperText Transfer Protocol) on the web (Bizer, et al 2009). …”

“…Tim Berners-Lee, inventor of the Web and proponent of the Semantic Web, outlined a set of rules for publishing linked data, paraphrased along the following lines (Bizer, et al 2009, Berners-Lee, et al 2001):…”

Using the Heterogeneous Database and Linked Data Technologies with Case Study of Thai Local Government Planning Database

“…Federated database systems can provide a user interface, enabling users to store and retrieve data in multiple databases with a single query even if components of databases are heterogeneous. In a federation of heterogeneous databases [7], there is the need for data sharing among the diverse databases, and for resource consolidation of all supporting software, hardware and personal, although each database has its own autonomy in terms of, for example, its integrity constraint, application specificity, and security requirements.…”
