An inscription is a cultural heritage that records archaeological intellects and accounts of a nation such as history, language, medicine, etc. Although inscriptions are the most reliable primary historical evidence, accessibility to, and understanding of them are restricted due to their dispersion, their deteriorating conditions, and the complications of the ancient language itself.  Nevertheless, digitalization is a possible means that enables users to acquire the bodies of knowledge in inscriptions. At present, digitalization allows digital collection of metadata which in turn explains inscribed digital data. Digitized inscription collection of metadata, however, requires the development of metadata schema appropriate to the inscriptions’ physical characteristics and contents. It has to be in line with the usage behaviors, requirements and expectations of the users. This article explains the concept in the development of metadata schema for the management of digitized inscription collections through literature review and presentation of the research conceptual framework.
