The Digital Humanities Observatory (DHO) was a research project of the Royal Irish Academy and part of the Humanities Serving Irish Society (HSIS) initiative. It provided expertise and knowledge to digital research projects in the arts and humanities in Ireland. Through activities such as a DHO Summer School, practice-based workshops, seminars, symposia and consultations the DHO helped researchers in Ireland be aware of and stay current with developments in the creation, use, and preservation of digital resources. The DHO developed DRAPIer, a database of digital research projects in Ireland and DHO:Discovery, a portal to collections of Irish cultural artefacts.
