Since the last few years, E-culture - a new term that describes the Information Communication Technology (ICT) roles in humanities has been introduced. E-Culture is an application that applies ICT for culture. Cultural heritage is a material culture or cultural artefact which functions as national or ethnic identity. It also has economic value such as tourism industry. Meanwhile, Culture itself is a complex and dynamically evolving system. A country that has many and heterogeneous ethnic groups-such as Indonesia-needs to manage its cultural artifacts. In this paper, Ethno-Grid which is a grid computing based technology is proposed. It acts as a supporting infrastructure in E-Culture. The architecture of Ethno-Grid consists of some major module services such as those for archaeological, linguistic, and cultural applications.
