Linked Data as Integrating Technology for Industrial Data

Abstract

In a globalised world the process industry faces challenges regarding data management. Rising demands for agility and rapid shortening of innovation cycles have lead to project-based collaborations. Highly specialised small and medium enterprises are forming “virtual companies” for their mutual benefit. However, today’s industrial data structures are very heterogeneous, complicating collaborative work and hindering the flow of data between stakeholders from different domains. Existing solutions are too rigid and potentially cumbersome. A broad gap still exists between the need of virtual companies to share data from mixed sources in a controlled way and the technologies available. The authors’ approach uses semantic web technologies to represent industrial data in a generic way. Major advantages in comparison to traditional approaches arise from the inherent merging abilities and the extensibility of Linked Data. Distributed information spaces from different domains can be condensed into an interlinked cloud. Existing data can be integrated either on-the-fly using appropriate adapters or by complete migration. Furthermore, operations from graph theory can be performed on the Linked Data networks to generate aggregated views. This article discusses a set of proven web technologies for cloud-driven industrial data sharing in virtual companies and presents first results.

Integrating linked data into the content value chain

“…But a look into newsrooms reveals that there is a mismatch between the scientific progress and the uptake of semantic metadata in the realm of the news industry. 17 One of the reasons lies in the underdeveloped metadata culture within news companies where due to missing competence, dense delivery dates and a lack of convenient service-supported workflows the collaborative maintenance of a well-curated metadata base is simply out of scope. But as most of the work discussed in this paper builds on technological preconditionslike available domain ontologies, well annotated media files or competence in natural language processing -that have not yet been integrated into the content and workflow management systems available in newsrooms, we cannot expect to see these solutions soon being implemented without threatening to disrupt established editorial workflows or content delivery mechanisms.…”

Was den Digitalen Zwilling zum genialen Kompagnon macht

“…Eine Schlüsselaufgabe des Digitalen Zwillings ist die Vernetzung der Partialmodelle zu einem integrierten Informationsraum zu organisieren und zu koordinieren sowie (Roh‐)Daten und Algorithmen dauerhaft vorzuhalten und für die zugriffsberechtigten Menschen und technischen Systeme leicht verfügbar zu machen. Eine besondere Bedeutung haben dabei Metadaten, also Information, die den notwendigen Kontext liefern, um relevante Inhalte leichter finden, bewerten und in offenen Innovationsprozessen handeln zu können .…”

“…Im Fokus steht die effiziente Einbindung der durch NOA bereitgestellten Information in semantische Netze. Diese erhöht die Fähigkeit verfahrenstechnischer Anlagen zur schnellen, weitgehend automatisierbaren Anpassung an volatile Produktionseinflüsse durch Plug-and-produce oder Measurement-ondemand, wenn Aspekte der Informationssicherheit und der Gebrauchstauglichkeit zu berücksichtigen sind [6].…”
