The Asia-Pacific Conferences on Conceptual Modelling provide an annual forum for disseminating the results of innovative research in information modelling and related areas. The amount, complexity and diversity of information held in computer systems are constantly on the increase, and so are the requirements and challenges to be met for useful access and manipulation of this information. Conceptual modelling is fundamental to the development of up-to-date information and knowledge-based systems. The conference series aims on bringing together experts from all areas of computer science and information systems with a common interest in the subject.
