Test Requirements
this document defines each test in Requirements See Digitization standards Folder Structure and bdrc-audit prototype to do list
The test subject is a set of files in a path. The audit user inputs test parameters. Each test may have its own set of parameters.
For most tests, the required input is the container of a project. This structure is named the Standard Project Structure The container is a folder which contains: - a Bibliographic Info Sheet in Excel format - a directory named "archive" which contains subfolders (no naming convention) - a directory named "images" which contains subfolders (no naming convention)
Audit number of files per folder
Test Parameters
Path to a folder containing a Standard Project Structure
Success criteria:
Passes only when: * every subfolder contains only files whose file name ends with a number. * The numbers in the file name endings form a series 1..n where n is the number of files in the folder. * Numbers may contain leading zeroes. It is not required that each file contain the same format. For example,
W42_I4242_0001.jpg
W42_I4242_2.jpg
is a valid sequence for a two file folder.
File Type
Test parameters
- Path to a folder containing a Standard Project Structure
- a designation of the folder containing the archival master (default name:
archive) - a designation of the folder containing the web images (default name:
images)
Success criteria:
Passes only when: * the archive files contain only images which match these requirements:
| Feature | Standard |
|---|---|
| File format | JPEG 2000 (.j2k), wavelets compression, highest data size |
| Resolution | 600 ppi/dpi |
| Color profile | RGB, 24-bits |
| Pixel dimensions | consistent width |
| ~~Quality~~ | ~~1 page per image, no borders, no scan lines, no artifacts~~ |
The Quality aspect cannot be determined by programmatic inspection, so it is not a requirement in the audit phase.
- the web images folder files have the following properties:
| Feature | Standard |
|---|---|
| File Format | JPEG (.jpg) for color pages, TIFF G4 compression (.tif) for text only pages |
| Resolution | consistent ppi/dpi |
| Color Profile | RGB 24-bits for JPEG, BW 1-bit for TIFF |
| Pixel dimensions | consistent width |
| File size | smaller than 400 KB |
Canonical paths
Test Parameters
- Path to a folder containing a Standard Project Structure
- Work Name: an unformatted text string
- Volume names: a list of unformatted text strings, representing the volumes in the work.
Note this document does not specify formats for work and volume names.
Success Criteria
This test passes when:
- the last element of the project folder is the work name.
