Image embedded metadata in cultural heritage digital collections on the web

Abstract

PurposeThe purpose of this paper is to investigate the availability of embedded metadata within images of digital cultural collections. It is designed to examine a proposed hypothesis that most digitally derived images of cultural resources are stripped of their metadata once they are placed on the web.Design/methodology/approachA sample of 603 images were selected randomly from four cultural portals which aggregate digitized cultural collections, then four steps in the data collection process took place to examine image metadata via the web-based tool and windows application.FindingsThe study revealed that 28.5 percent of the analyzed images contained metadata, no links exist between image embedded metadata and its metadata record or the pages of the websites analyzed, and there is a significant usage of Extensible Metadata Platform to encode embedded metadata within the images.Practical implicationsThe findings of the study may encourage heritage digital collection providers to reconsider their metadata preservation practices and policies to enrich the content of embedded metadata. In addition, it will raise awareness about the potential and value of embedded metadata in enhancing the findability and exchange of digital collections.Originality/valueThis study is ground breaking in that it is one of the early studies, especially in the Arab world, which aim to recognize the use of image embedded metadata within cultural heritage digital collections on the web.
