The evolution of digital technologies affects parliaments worldwide, triggering investigations to change their operational functions. Being rather conservative organizations, parliaments use dig-ital tools and services that tend to adopt mature emerging technologies (ParlTech) for their digi-tal transformation. Inevitably, digital parliamentary environments become amalgams of several components, features, and types. This research effort is mainly a literature review of the term ‘digital parliament’, and the digital technologies used for the creation of a digital parliamentary environment. It discusses the findings during the last years and identify the research gaps on them. A set of answers is also provided as a roadmap for ‘digital’ parliament creation.
