Recogito is a web-based environment for collaborative semantic annotation. It is open source software, and provides support for working with either text or image documents, including those served via the IIIF protocol. Originally, the tool has been designed for geographic annotation, i.e. the transcription, marking up and geo-resolving of maps and geographical texts (such as itineraries and travel reports) in the context of historical scholarship, e.g. to map or extract data from a source, or to prepare a digital edition. Over time, however, Recogito’s feature set has grown to provide more general annotation functionality, broadening the scope for further potential application areas. Following up from an earlier article we published in e-Perimetron in 2015, in which we first introduced Recogito, this article looks back on the past four years of use and development. We present how Recogito has technologically evolved; how it has been applied in practice in different projects and for different purposes; and how a vibrant user community has sprung up around it that is shaping its further development. The paper also looks forward to some planned next steps, and sets out our future vision for Recogito’s long-term development and sustainability.
