We report on the Linked Data platform developed for the administrative boundaries governed by the Ordnance Survey Ireland (OSi), as they wished to serve this data as an authoritative Linked Open Data dataset on the Web. To implement this platform, we have adopted best practices and guidelines from the industry and academia. We demonstrate how this dataset can be combined with other datasets to add a spatial component to information. We believe that the publication of this dataset not only provides opportunities for third parties (including scholars) in their activities, but that this outcome of this initiative is of importance, as the OSi made the authoritative dataset available. With the current platform deployed, future work will include the inclusion of other (closed) datasets and the investigation of access mechanisms.
