Beyond scholars, the project targets four further user types: instrumental players choir singers orchestras and music enthusiasts with corresponding web applications providing specialised views of the same underlying knowledge graph.
TROMPA provides for contribution of expert insights as citable, provenanced annotations, supporting analytical workflows and scholarly communication. TROMPA-Towards Richer Online Music Public-domain Archives-addresses this through a knowledge graph interweaving composers, performers, and works described in established digital music libraries, facilitating discovery and combined access of complementary materials across collections. While each repository reveals rich information for scholarly investigation, the unified exploration and analysis of separate digital collections remains a challenge. Digital repositories provide access to publicly licensed score images, score encodings, textual resources, audiovisual recordings, and music metadata. The turn toward the digital has opened up previously difficult to access musical materials to wider musicological scholarship.
