In this paper we propose a digital publishing system that supports authoring of digital contents. The proposed system can dynamically update open resources, a publicly available web content, with tracing technique. Content scraping directly from the web and combining them into their own documents (e.g., e-book, e-textbook) are getting popular for authors. However, there was a little effort to design a system that automatically verifies the scraped content, particularly when the original source itself was being updated. In this research, we have designed a metadata for tracing open resources where the primary objective is to search and scrap web content - such as text, images and videos. Using this metadata will recognize the change of web contents to identify if the latest version of the open resource is being used during the document authoring process.
