Serving Ireland's Geospatial Information as Linked Data (ISWC 2016 Poster)
1 like531 views
Ordnance Survey Ireland (OSI) implemented a new spatial data model called Prime2 in 2014 to enhance the publication of geospatial information as linked data. The initiative aims to make public datasets more accessible, enabling third parties to develop applications and integrate spatial information with authoritative OSI data. Future plans include extending access to 'closed' geospatial data and collaborating with other organizations to refine the linked data platform.
Serving Ireland's Geospatial Information as Linked Data (ISWC 2016 Poster)
- 1. Serving Ireland's Geospa2al Informa2on as Linked Data Mo2va2on In 2014, the Ordnance Survey Ireland (OSi) delivered a newly developed spatial data storage model known as Prime2. With Prime2, OSi moved from a traditional map- centric model towards an object-oriented model from which various types of mapping and data services can be produced. At the same time, the OSi aims to adopt Linked Data to enable third parties to explore and consume some of OSi's authoritative datasets. Research Ques2on How can we take the Prime2 model as a basis for publishing OSi's authoritative geospatial data as Linked Data on the Web whilst adhering to best practices in the domain of geospatial information? Goal To lay the foundations of a semantic architecture and Linked Data platform for the OSi. Starting from publicly available boundary data, we support 2 use cases: 1. Provide different generalizations of the boundaries 2. Capture evolution of boundaries, e.g. as ordered by statute instruments. Poten2al Impact • Availability of public data via standardized technologies. • Allowing third par/es to develop novel applica/ons. • Adding spa/al informa/on to external datasets with OSi’s authorita/ve informa/on and OSi’s Linked Data endpoint as an informa/on integra/on hub for Ireland through loca/ons. The ADAPT Centre for Digital Content Technology is funded under the SFI Research Centres Programme (Grant 13/RC/2106) and is co-funded under the European Regional Development Fund.
