Polifonia is driven by 10 pilot use cases addressing preservation, management, studying musical heritage (MH), and interacting with it. Being real-world use cases – for example the Italian bell heritage, organs in the Netherlands, access to musical heritage for deaf people or the identification of recurring melodic patterns –, these pilots provide a means to validate Polifonia’s computational solutions, to strengthen the project’s outreach, and to integrate new scenarios, early-adopters and stakeholders. They are developed by interdisciplinary teams of researchers from the humanities and social sciences, and from computer science. This deliverable presents the second version of a “socio-technical Roadmap” which aims at providing a common framework to all pilots for: 1. Coordinating collection of resources for use in the pilots, 2. Gathering requirements from internal and external adopters/stakeholders, 3. Setting objectives and challenges and mapping them from specific domains to the technology provider work packages, and 4. Monitoring validation within the pilot tasks. While the first version of the Roadmap, D1.1 released at M69, adopted a bottom-up approach, the current version proposes a generalization of methods to share, interlink, articulate and validate resources, tools and results within a decentralized yet interconnected Ecosystem. This generalization is based on an interdisciplinary dialogue between a) the musicologists, linguists, historians and curators working at the pilots and b) the computer scientists, designers and researchers in cognitive sciences involved in the project. The outcome is the result of a continuous interaction between WP110 – the driving force of Polifonia and place where the pilots happen – and the technology provider work packages (WP2-5). An important vector of this dialogue are the "SMS-tools" – Stories, Maninpasta, and Survey –, which were presented in detail in the first version of the Roadmap. These tools have helped a) to constantly keep and update a centralized view of the information collected (Survey), b) to strengthen synergies through practical and concrete work between researchers from different disciplines (Maninpasta), and c) to collect the requests, needs and expectations of the pilots (Stories). As central pillars of the Roadmap, they have allowed both to identify and to promote common principles, methods and approaches among the pilots while preserving their specific needs and orientations. The four sections of this deliverable relate to the four objectives outlined above and critically present how the tool’s current state of development, methods and strategies contribute to the Roadmap. While the deliverable is organised according to the four objectives, the tools presented do not focus exclusively on one of them but cover several of them: the Survey, for example, contributes to both resource collection and validation monitoring. For methodological reasons, however, the tools will be presented in detail in the section in which they play a key role. Beyond the presentation of a set of tools, principles and methods that can be applied to the pilots, that regulate their interaction and that can be transferred to other use cases, the objective of this document is also to describe how the collaborative work took place and how the framework was shaped. To facilitate the reading of this deliverable, a glossary (which provides a resolution of acronyms, short definitions and links) is included in Appendix 1. Appendix 2 gives a presentation of the pilots and their objectives. Appendix 3 summarizes the essential data of WP1, to which the Roadmap is attached and which constitutes the driving force of the project. Appendix 4 provides key data on the other Polifonia work packages. The last two Appendices 5 and 6 give an update of the pilot’s Stories and of the Survey.
