Digital Production Services (DPS) is responsible for digitization of materials in support of scholarship, research, and teaching, as well as metadata production and consulting services for Library and academic units undertaking digital projects.
DPS work ranges from projects designed in collaboration with Brown researchers and the Library’s Center for Digital Scholarship to the digitization of “signature collections” from Brown’s world-renowned Special Collections. DPS also offers imaging and metadata consulting for grants and other University initiatives.
Digital imaging technology has become ubiquitous, but in order to achieve high quality image capture and reproduction DPS adheres to imaging best practices established by the cultural heritage and library communities at large. In addition to the image capture stage, color management workflows and principles are also important to implement in relation to viewing conditions (display environments and monitors) and printing (output devices and materials; DPS does not offer printing services).
Handling guidelines provide instruction on the proper handling of archival and special collections materials during digitization, and are modified for specific projects based on the materials being digitized and their condition. Review of the condition of the materials takes place prior to the beginning of a digitization project and is done in consultation with Preservation staff. Special care is taken with fragile, rolled, or oversize materials.
The various tasks performed by Digital Production Services are tracked by an in-house project management system. From the creation of a digital surrogate entry to the publication of its METS record, the system also records user permissions, equipment and software registration, and provides links directly into the Brown Digital Repository (BDR). Security is integrated with a campus-wide authentication system. [top]

Imaging Targets (color swatch and scale references):
Metadata provides information about a particular object or resource. This may include descriptive information, information about how an object or resource is formatted, and who may access it. Metadata may be generated automatically or constructed by hand. It is usually constructed in the eXtensible Markup Language (XML), and, in DPS, is created according to certain national and international standards described elsewhere.
|Descriptive metadata||Descriptive metadata identifies a resource for identification and discovery. Elements such as author and title are examples of descriptive metadata.|
|Administrative metadata||Administrative metadata contains information to assist in managing a resource. This would include information about who created the file and when.|
|Technical metadata||Technical metadata describes how a resource was created, its format, and other technical information that enables the object to be delivered correctly.|
|Structural metadata||Structural metadata provides information on how an object is constructed, for instance, the order of pages in a book. It documents the relationship of individual files in a multi-file object whether it be images, audio or video.|
|Preservation metadata||Preservation metadata enables files to be usable over long periods of time. It records actions taken on files, processing history, and technical characteristics.|
|Rights metadata||Rights metadata records who owns the rights to an object, as well as other information such as copyright status, licensing information, permissions, and other information related to use of the object.|
