Serving Ireland's geospatial information as Linked Data.
Boundary data is made available via a Triple Pattern Fragments server, which allows for efficient client-side querying and minimize the load on a server. OSi's Triple Pattern Fragment server is hosted on http://vma01.adaptcentre.ie/. Users can query this server with the following the following web client: http://client.geohive.ie/.
The Triple Pattern Fragments server currently contains three datasets:
Note that a Triple Pattern Fragments server is used to retrieve simple triple patterns and are not really suited for exploring and querying the data. The following link shows how one can retrieve a list of counties with the fragments server: click here. If one wishes to retrieve a list of counties (and their labels), one can execute the following query in the client: click here.
HTTP URIs follow Linked Data principles and resolve to a Web page or RDF file with content negotiation. For instance, if one follows the HTTP URI for County Dublin http://data.geohive.ie/resource/county/2AE19629144F13A3E055000000000001, it will redirect to http://data.geohive.ie/page/county/2AE19629144F13A3E055000000000001 describing Dublin in HTML.
OSi "boundary" database contains geometrical representations of the boundaries of the administrative units (e.g., county, city, and rural area) of the Republic of Ireland. These are generalized up to 20, 50 and 100 meters. The following table allows boundary data to be downloaded in the RDF Turtle format.
