Integrating multimedia data in a meaningful way requires keeping track of the who, what, where, when, and how of many kinds of data and metadata in different formats. The PORTAL-DOORS-Project (PDP) was formed to design and build the Nexus-PORTAL-DOORS-Scribe (NPDS) cyberinfrastructure for managing and distributing resource data and metadata in a manner compatible with both the established lexical web and the developing semantic web. PDP-DREAM software, archived at, represents the first publicly available, open-source implementation of NPDS. It provides RESTful web services for software agents and user-friendly web applications for human agents so that individuals and organizations can create and publish their own problem-oriented and domain-specific repositories customized for their own purposes. In this report, we also introduce the NpdsQuads format with an approach to formatting the comments of N-quads files as name-value pairs for content from NPDS records which can be exported from and imported to NPDS repositories. We then describe the use of these tools in the curation of the PDP-DREAM ontology, which serves as the foundational ontology for the NPDS cyberinfrastructure. Finally, we discuss the planned use of PDP-DREAM software in a medical imaging clinical trial for multiple sclerosis.
