The Knowledge Graph As The Interoperability Foundation For An Augmented Reality Application: The Case At The Dutch Land Registry

The concept of the knowledge graph supports insight to a given context through the provision of standards-based mechanisms for accessing open and interoperable data. In doing so, the graph uses the power of the web to integrate data from distributed data sources and make this data available to end users in a transparent, flexible and application-independent manner, either by simply displaying data in the browser based on a dereference unique resource identifier or in an application built using the knowledge graph as the source. With the latter approach, the knowledge graph remains independent of the applications making use of it as a data source, where the connection between the graph and the application is achieved through interfaces which are completely based on open standards, most commonly through the use of a SPARQL endpoint. Indeed, chatbot applications often make use of the knowledge graph in this way but this paper aims to present the potential for Augmented Reality (AR) applications to be similarly built using knowledge graphs. By presenting this potential, this paper will argue that AR applications exemplify the potential opportunities that fully open, interoperable and standards-based approaches to data publication, such as the development of knowledge graphs, have and, therefore, will become key drivers within the organization in the investment of the further development of the concept of the knowledge graph in the future and improved accessibility of data for end users.
