Modeling Digital Humanities Collections as Research Objects

Advancing digital libraries to increase the sustainability and usefulness of digital scholarship depends on identifying and developing data models capable of representing increasingly complex scholarly products. This paper considers the potential for an emergent model of scientific communication, the \textit{research objects} data model, to accommodate the complexities of digital humanities collections. Digital humanities collections aggregate and enrich diverse sources of evidence and context, serving simultaneously as "publications" and dynamic, interactive platforms for research. The research objects model is an alternative to traditional formats of publication, facilitating aggregation and description of all of the inputs and outputs of a research process, ranging from datasets to papers to executable code. This model increasingly underpins research infrastructures in some scientific domains, yet its efficacy for representing humanities scholarship, and for undergirding humanities cyberinfrastructure, remains largely untested. This study offers a qualitative content analysis of digital humanities collections relying on a content/context analytical framework for characterizing collection components and their interrelationships. This study then maps those components and relationships into a research objects model to identify the model's strengths and limitations for representing diverse digital humanities scholarship.
