CLARIAH-PLUS focus on four different areas in the Humanities. Areas that function as precursors for other disciplines and that together represent all forms of data: text, image, audio-visual material and structured data (databases).

The four focus areas are:

In each area multidisciplinairy teams of humanity scholars, computer scientists and data providers, work together in order to curate existing data and applications, and link them together. The four focus areas will be supported by technology (wp 2).

Although CLARIAH focuses on four areas, other disciplines from both the Humanities and the Social Sciences can submit their data and applications, and participate in, for example, curation projects and research pilots.
