Project Standards and Technical Approaches

Metadata Standards

TIMEA provides as much information (or "metadata") about material included in the archive as we can, since we intend for our resources to be as useful as possible for scholars. To capture and present the metadata about texts and images, we use the Dublin Core standard. Dublin Core is so flexible that it can be applied in many different ways, so we have adopted the Collaborative Digitization Program Dublin Core Metadata Best Practices for describing digitized objects, making some local modifications.

Please see How to Read a TIMEA Metadata Record for more information about TIMEA's metadata standrads.

Scanning Standards

We use a Betterlight scanning back with a Rodenstock lens, TTI copy stand, and TTI book cradle to capture the highest quality scans and minimize wear and tear on the original books and artifacts. Images are scanned at 24-bit color, 600 dpi, while text pages are scanned at 400 dpi, 24-bit color.

Text Mark-up Standards

All texts are encoded in TEI-Lite to facilitate scholarly analysis. (TEI is the major markup standard for humanities texts.) Texts contain page images of the original books so that readers can get a sense of the original object and verify transcriptions. We follow guidelines put forward by the University of Virginia and the University of North Carolina as well as the TEI Text Encoding in Libraries Guidelines for Best Encoding Practices for TEI Level 4 in creating TEI texts.

GIS Maps

The interactive maps used to display local datasets and to link to the archived materials use ESRI’s ArcIMS technology.  The on-line maps are customized using ArcXML, a GIS extension to standard Extensible Markup Language (XML).  The datasets for the maps come from various sources, as listed here.

Educational Modules in Connexions

Our educational modules are made available through Connexions, a collaborative, community-driven approach to authoring, teaching, and learning that seeks to provide a cohesive body of high-quality educational content to anyone in the world, for free. See Using and Creating TIMEA Educational Materials in Connexions.

DSpace Content Management System

Texts and images are stored in DSpace, an open source institutional repository system. We are making some customizations to support the display of XML texts, and are implementing the Manakin XML-driven user interface to support our customized look and features.
