Abstract
Linked Logainm is the newly created Linked Data version of Logainm.ie, an online database holding the authoritative hierarchical list of Irish and English language place names in Ireland. As a use case to demonstrate the benefit of Linked Data to the library community, the Linked Logainm dataset was used to enhance the Longfield Map collection, a set of digitised 18th–19th century maps held by the National Library of Ireland. This paper describes the process of creating Linked Logainm, including the transformation of the data from XML to RDF, the generation of links to external geographic datasets like DBpedia and the Faceted Application of Subject Terminology, and the enhancement of the Library’s metadata records.

Notes
- 1.
- 2.
- 3.
Since we are interested in matching Irish names we did not consider the GeoLinkedData dataset.
- 4.
Further details regarding the comparison functions are provided at https://www.assembla.com/spaces/silk/wiki/Comparison.
- 5.
This function allows to define an approximation value to account for offsets in the geographical locations. We have currently set this value to 1 kilometre.
- 6.
A description of the GeoNames feature codes can be found at http://www.geonames.org/export/codes.html.

This matching was determined using a SPARQL query.
