Community-generated digital content (CGDC) is one of the UK's prime cultural assets. However, CGDC is currently 'critically endangered' due to technological and organisational barriers and has proven resistant to traditional methods of linking and integration. The challenge of integrating CGDC into larger archives has effectively silenced diverse community voices within our national collection. Our Heritage, Our Stories (OHOS), responds to these urgent challenges by bringing together cutting-edge approaches from cultural heritage, humanities, and computer science. Existing solutions to CGDC integration, involving bespoke interventionist activities, are expensive, time-consuming, and unsustainable at scale, while unsophisticated computational integration erases the meaning and purpose of both CGDC and its creators. Our approach is fundamentally different: our project is using innovative multidisciplinary methods, AI tools, and a co-design process to make previously unfindable and unlinkable CGDC discoverable in our virtual national collection.
