摘要:Grey literature is one of library material types which can be accessed restrictedly by the patrons. The paradox is that grey literature contains very important information to support research and study. Therefore by building a digital library it is assumed both security and accessibility of users to the grey literature content will be accomodated. Designing a digital library as an institutional repository for UPH by using the Zachman Framework will take a very important role in defining the technical and normative features of an ideal digital library. In addition to, the exploration and modification of DSpace by using Software Evolution method will also define the technical and normative features of DSpace performance. The result of these will be compared to one another by using a simple relevancy test procedure. The result are 90,625 % of relevancy degree on technical features and 95,7 % of relevancy degree on normative features. According to the result, it can be claimed that a high relevancy degree is found between the pre-made architectural system of digital library and the post-modification of DSpace program. Keywords: digital library, DSpace, grey literature, institutional repository, Zachman Framework.
