E-LAUTE (https://e-laute.info/) is creating a comprehensive edition of German renaissance lute tablatures (GLT), a historically widespread music notation that has been largely neglected by modern research. It interlinks music and textual encodings, notation images, audio, semantic annotations, and bibliographic metadata by using open data formats and Linked Data throughout the entire process. Additionally, it builds on research data and information architectures provided by the Technical University of Vienna (research workflow management) and the Austrian National Library (ÖNB; GAMS digital edition platform and triplestore). We are extending the ÖNB platform with facilities for incorporating multifaceted music information, and we are augmenting the Music Encoding Initiative’s (MEI) existing XML schema for the representation of GLT documents. We contextually enrich the MEI encodings through interconnection with textual encodings of contemporary lyrics and instructional material, IIIF facsimile images, audio recordings (produced both project-internally and externally), and additional metadata. To do so, we apply Linked Data ontologies, XML transclusions between encoding schemas, and Web Annotations for external contributions through decentralized Solid pods. We aim to create a central hub for managing the enriched data and for publishing the results in uniform and state-of-the-art formats (e.g. JSON-LD), providing open APIs (e.g. SPARQL) and contributing innovative approaches to music informatics and musicological research, thus serving the needs of music researchers, practitioners and enthusiasts alike.
