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.

Results and Discussion
• Deployment of the Linked Data Platform at
http://data.geohive.ie/
• An approach to organize the geospatial information and
to capture the evolution thereof.
Future Work
• Inclusion of “closed” geospatial information such as the
geometries of buildings and investigate access control
mechanisms to cope with different licenses and policies
• Inclusion of other adminstrative boundaries; e.g., of the
2011 CENSUS and link those with http://data.cso.ie/
