Abstract: This paper reports on the experiences of building a linked geo data coordinates translation API and some of the issues that arose. Beyond the basic capacities of SPARQL, a specialized API was constructed to translate obsolete British Trench Map Coordinates from the Great War into modern WGS84 reference systems. Concerns over current methods of recording geographic information along with accuracy and precision information are reported on. Open questions about managing the opportunistic enrichment of geographical instances are discussed as well as the scalability pitfalls therein.
