After experimentation with various data models and assessment of their relative strengths and weaknesses, it was concluded that Linked Places Format (LPF) provides an ideal basis for the representation of cultural heritage data. This format, conceived and developed principally by Karl Grossner for the World Historical Gazetteer (a partner in the Pelagios Network) is based on various widely-accepted data standards, principally GeoJSON and RDF, and a short explainer can be found here. While collecting and developing a diverse range of datasets from its project partners, LaNC has identified numerous desirable extensions to LPF which are documented in a JSON Schema, and these extensions may in due course be adopted as part of the LPF standard.
