Overview

Digital Collections at the University of Maryland

These materials are part of the Treasury of World's Fair Art & Architecture digital collection, which is part of the Digital Collections of the University of Maryland Libraries. The materials in this collection can be access through this site or through the interface for all Digital Collections.

Naming Conventions

Images created for this digital collection were given identifying filenames using the following convention:
wfc-1904-stl-26-0001-0001.jpg
(collection-year-fair-series-object-part.ext)
 
Note that the city name is lowercase and that both the object number and the part number have four ordinals.

Essays created for this project were given filenames with the prefix " wfc-essay " and then numbered consecutively with two-digit numbers in the order in which they were encoded.
wfc-essay02.xml
After images and essays are added to the collection they are assigned unique persistent identifiers instead of filenames. The original filename is retained in the descriptive metadata as the <identifier> element.


Metadata

UMDM & UMAM

All objects in the Digital Collections Repository are described with the University of Maryland Descriptive (UMDM) and Administrative (UMAM) Metadata schemes. The DTD and tag library for these schemes can be found at http://www.lib.umd.edu/dcr/publications.html

Controlled Vocabularies

All items in this collection were classified using both the Library of Congress Subject Headings and Thesaurus for Graphical Materials. All names in metadata records use authorized forms from the Library of Congress Name Authority File.


Images

Selection Criteria

This digital collection contains images from World's Fairs that have content related to art (including performing art) and architecture (including landscape architecture). Materials in this collection include:

Scanning Specifications

Images in this digital collection were scanned in three batches. The first batch contained images from the 1876 and 1904 Fairs. These items were scanned at their original size as Tiff 6.0 images and a significant portion were done with a ¼ - ½ inch border around the object. These images were created at a resolution 500 dpi and higher using an 8-bit RGB color profile as the master image.

Some images from other World's Fairs were scanned in a second batch. These were also scanned as Tiff 6.0 images at their original size leaving a ¼ - ½ inch border around the object. All scans were done at 600 dpi using an 8-bit RGB color profile.

A small selection of images were taken from a previous online exhibit and exist only as 72 dpi JPEG images. These images will be rescanned at a higher specification at a future date.

Tiff and JPEG images from both batches were ingested into the digital repository and access copies were created using Zoomify software.


Essays

DTD

This project uses the TEI Lite document type definition (DTD) created by the Text Encoding Initiative. To view this DTD, click on the above link and save this file as "teixlite.dtd". This DTD, a list of rules and syntax for TEI lite XML documents, was used to parse the encoding of essays for this project to ensure consistency in encoding practices.

Template

This document contains the basic outlines for an XML essay for this project. Information in the header that will be consistent throughout essays is included and information that needs to be added is indicated by double quotation marks ("??"). To begin encoding a new essay, click on the above link and save the file as "template.xml". Search for double quotation marks and fill in the requested information. Once information is entered, remember to save the file with the name of the document that is being encoded and not as "template.xml".

List of Elements

<!ENTITY img1 SYSTEM "filename??" NDATA JPEG>
The first section of the document, before any elements are entered contains the document type definition and the entity references. The template has pre-encoded the document type definition but the entity references will need to be finished by the encoding. These references point to any images that should be included in the document when it is viewed. The stub of an entity reference already exists in the document. To finish it, simply add the filename, including the extension, of the image to the part of the reference that says "filename??". If more than one image should be included in the document, copy the entity reference and paste it directly after the ">" of the first one. In addition to adding the filename of the new image, change the section that says "img1" to "img2". For any subsequent images follow the same process increasing "img" by one number each time.

<TEI.2>
The id element of this attribute required the object's digital repository-generated persistent id (pid). This element will be generated and updated after the document is uploaded into the digital repository.
