Mapping Culture (GlamMap) verifies scalability, societal relevance, innovation and commercialisation potential of a metadata visualisation tool developed in a pilot within the ERC project ‘Tarski’s Revolution’ (TRANH). We want to propose a visualisation software package aimed at the GLAM (cultural heritage) industry sector. The software we envisage (GlamMap) will enable GLAM actors to provide web-based visualisations of their collections of books, paintings or movies in a flexible, insightful, cost-effective and user-friendly way to the benefit of various kinds of users, including both researchers and the public at large.We shall build a visualisation prototype (small-scale technical validation) of GlamMap integrating a data harvester. Our team will include two programmers and a technical supervisor coordinated by the applicant (PI), possibly aided by a student assistant. The data harvester benchmarking will rely on the data manually collected for the original ERC project pilot. Market research to investigate competitiveness of our software with respect to alternative solutions will be conducted working in partnership with members of the GLAM industry sector. Market research for GlamMap will also include investigating viability of a (open source) Red Hat-style business model.
