TDL Glossary

The following are brief Tufts Digital Library-specific definitions for terms used throughout the TDL:

Glossary

term definition
Advanced Image Viewer TDL Java Applet allows for a more interactive viewing experience than the basic viewer. Advanced Image Viewer opens in a new page. Default view is set to fit the image within the viewing space. Other viewing options include 100% and the ability to pan the image by clicking and dragging on any point, zooming in and zooming out to fit. You must have Java installed on your computer for this tool to function.
All Search A search using the broadest combination of information about and included for a resource. The body of text documents, bibliographic information about the text documents, and descriptive information about images are queried.
Basic Image Viewer Allows patrons to quickly view a low resolution image. Requires no plug-ins or applets.
Fulltext Any text included in a document, as defined as the front matter, body, and back matter. This encompasses title pages, dedications, the work itself, epilogues, etc.
Fulltext Search A search which is restricted to just the front matter, body, and back matter of a document. See full text.
Image

A resource that is photographic in origin or visually accessible in its near-to original form, such as a scanned page of a book or a letter that has not been transcribed to text.

Most images are not discoverable using full text searching. However, some documents provided as images (PDFs, etc.) may include hidden transcriptions and will provide results in a full text search.

Image is also a term used to identify the format of a resource. "Image" can be entered as a constraint in the advanced search metadata "type" category in order to filter returned serach results.

Metadata

Terms used to identify and describe a resource. TDL uses the following metadata and text document structuring schemes: METS, Dublin Core, EAD, TEI.

TDL makes OAI-compliant metadata available for harvesting.

Metadata Search TBD
Resource Inspector The expandable area to the left of the viewing area in the TDL and below the basic and advanced search areas. Information and tools related to "inspecting" a selected resource are included in this area.
Text

A resource that is textual in origin or accessible in a transcribed form, such as a book that has been made accessible as a digital resoource or a letter that has been transcribed to serachable text.

Most texts are discoverable using full text searching and/or metadata seraching. However, some documents, or parts of them, may be provided as images (PDFs, image books, etc.). Unless they contain hidden transcriptions, they will not provide results in a full text search.

Text is also a term used to identify the format of a resource. "Text" can be entered as a constraint in the advanced search metadata "type" category in order to filter returned search results.
