Supporting the Data Lifecycle at a Global Publisher using the Linked Data Stack

In these times of omnipresent electronic devices, the ways of consuming information are changing and so too are the expectations of customers. Documentation and processing of pub-lishers' data, however, are lagging behind. Let's assume an accounting professional is working for a leading consultancy and is responsible for certifying tax returns for an international customer. In the future, the publisher aims to deliver more personalized and context specific information precisely fulfilling his need to track changes in information provided by a multitude of sources. The Linked Data Stack provides specialized tools for each Linked Data lifecycle stage (e.g. data enrichment, management of knowledge bases, reasoning techniques and semantic search support) and can consequently be used to facilitate the semantic content processing workflows. The Linked Data Stack and Life-Cycle The description of the Linked Data stack and the Linked Data lifecycle are based on earlier work in [1] and [2]. The Linked Data Stack is an integrated distribution of aligned tools that support the whole lifecycle of Linked Data from extraction, authoring/creation via enrichment, interlinking and fusing through to maintenance. The major components of the Linked Data Stack are open-source in order to facilitate wide deployment. The stack is designed to be versatile; for all functionalities there are clear interfaces, which enable the plugging in of alternative third-party implementations. In order to fulfill these requirements, the architecture of the Linked Data Stack is based on the following basic principles: • Software integration and deployment using the Debian packaging system: The Debian packaging system is one of the most widely used packaging and deployment infrastructures, and facilitates packaging and integration as well as maintenance of dependencies between the various Linked Data Stack components. Using the Debian system also facilitates the deployment of the Linked Data Stack on individual servers, cloud or virtual-ization infrastructures. • Use of a central SPARQL endpoint and standardized vocabularies for knowledge base access and integration between different tools: All components of the Linked Data Stack access this central knowledge base repository and write their findings back to it. In order for other tools to make sense out of the output of a certain component, it is important to define vocabularies for each stage of the Linked Data lifecycle.
