Basic embedded metadata for photos of art and architecture

2012-01-29

Looking for more detailed metadata? VRA Bridge Metadata Tools

Question, comments? emwg@vraweb.org

 

INTRODUCTION

 

Digital images contain data for such things as the camera model, photographer's name, and date taken. This data is referred to as “embedded metadata.” The following guidelines demonstrate how to create embedded metadata to describe the tangible creative works shown in photographs of art and architecture. The guidelines focus on five metadata fields that are widely used by image processing applications and web services: Creator, Title, Description, Keywords and Copyright Notice.

 

The aims of the guidelines are:

  • To provide a simple, common sense guide to describing creative works that makes a clear distinction between a work and a digital image of that work, i.e., when was the painting created and when was the photo of the painting taken.
  • To make use of existing embedded metadata features in image applications, without requiring special tools or plugins.
  • To provide a method for entering metadata easily into any image application. 

 

The guidelines will be helpful to the following types of users, among others:

  • Students describing their own work to share with other students; submit for class projects; contribute to institutional repositories; or post online.
  • Faculty describing their own work to send to colleagues, clients, galleries, museums or publishers; contribute to visual resources center databases and institutional repositories; or use for job applications and tenure reviews.
  • Freelance artists and designers describing their own work to use for web publishing or share with colleagues, clients, galleries and museums.
  • Visual resources professionals looking for a basic embedded metadata set to use for downloadable images.
  • Everyone searching for images in their desktops, or using images for web publishing.

Advice

 

Before you begin

 

Creator names and commas

  • Some applications use commas as separators (delimiters) to create a list of Creators.
  • If you enter: Joseph H. Taylor, Jr. it might be saved as:
    1. Joseph H. Taylor
    2. , Jr.
  • For maximum interoperability it is best to avoid commas.
  • If you need to use commas, test your application be sure you get the results you expect.

 

Plain text and semicolons

  • Even though plain text fields don't use separators the way list fields, like Keywords, do, it is still useful to separate independent parts of plain text with semicolons for readability and possible separation by other software.
  • The Description field will likely consist of several distinct pieces of information strung together, such as:
    • Francisco de Goya; The Third of May 1808; 1814; oil on canvas; 68 x 347 cm; Museo del Prado; ID: P00749; Public domain
    • This is a plain text list representing these individual characteristics of a painting:
      • Creator; Title; Date; Material; Measurements; Repository; ID; Rights
  • The (photo) Title field will be a combination of the title of the work and the particular view shown in the photo, such as:
    • Poplar Forest; southwest facade, showing west stairwell, south portico, and wing
    • This is a plain text combination of two individual characteristics:
      • Creative work Title; Photo view
  • By using semicolons it is clear where one characteristic ends and the other starts. Also, semicolons could be used to parse the information into separate columns of a spreadsheet for further processing.

 

Description

  • Your task is to concisely describe what it is, who made it, where it was made, how it was made, the materials of which it was made, and what it is about.
  • You can follow this with additional information such as construction details or historical context.
  • Be consistent regarding capitalization, punctuation, and syntax. Avoid abbreviations, but when necessary, use standard codes and lists for abbreviations (for example, the ISO abbreviations for countries).

 

Keywords and commas

  • Some applications use commas and/or semicolons as separators (delimiters) between keywords. Because of this, using commas as regular punctuation should be avoided.
  • If you enter: Castelli, Leo (American art dealer, 1907-1999) it will probably be saved as:
    1. Castelli
    2. Leo (American art dealer
    3. 1907-1999) 
  • To avoid problems, remove commas or replace them with another character:
    1. Leo Castelli (American art dealer. 1907-1999)
  • In some applications, surrounding a phrase containing commas with quotes will fix the problem.. e.g., "Castelli, Leo (American art dealer, 1907-1999)".  This is still risky because other applications might use commas as delimiters and mangle the words.
