Culture and natural history are life aspects that represent characteristic of one nation. Many problems and challenges in managing cultural heritage data are emminent, such as: unintegrated database, incomprehensive inventory, limited access to public, and so forth. Various data, applications, and technologies of cultural heritage and natural history are scattered and built with different formats and platforms. In order to overcome such problems and challenges, we proposed a framework, called eCultural Heritage and Natural History (eCHNH). This framework is developed based on Zachman Architecture Framework. We use it as a basis and guidance for digital preservation, accessibility and information sharing of cultural heritage and natural history, in the public and non-public domain. Zachman Architecture Framework assured seamless integration of eCHNH. Each component of Zachman Framework is integrated step-wisely in the eCHNH.. The first step is to integrate the various data. The second and the following steps integrate function, network, people, time and motivation, subsequently. The preliminary result shows that after all components being integrated into eCHNH portal, the preservation, accessibility, and information sharing among stakeholders are more visible.
