File and Folder Naming Guidelines
Use this baseline structure for item-level digital preservation files:
item-id_short-title_date
Practical example:
ca-013-001-002-001_hahira-gold-leaf_1973-01-04.pdf
| Part | What it means | Example |
|---|---|---|
item-id |
Unique identifier before the first underscore | ca-013-001-002-001 |
short-title |
Brief title using dashes between words | hahira-gold-leaf |
date |
Date or no-date value after the last underscore | 1973-01-04 |
sequence |
Optional page, scan, or item segment | p001 |
Why the separators matter
Keep dashes and underscores consistent so scripts can parse filenames reliably. The item ID is the string before the first underscore, and the date is usually the string after the last underscore. The item ID points to the collection, series, subseries when applicable, and item number. Dashes stay inside each information part, while underscores separate the major parts scripts need to read.
Core Rules
1. Case
Use all lowercase. File extensions must be lowercase.
2. Allowed characters
Use letters, numbers, dashes, underscores, and the period before the file extension only.
Do not use spaces or special characters such as:
\ / : * ? " < > | % + & @ ^ ~ # ! { } [ ] ( ) ; = ' ` , .
3. Separators
- Use underscores between major information parts:
item-id_short-title_date - Use dashes inside a string of words:
hahira-gold-leaf - Do not use underscores inside the item ID, title words, or date value except for approved access-copy suffixes such as
_nd_a
4. Date format
Use ISO-style dates:
YYYY-MM-DDwhen the full date is knownYYYY-MMwhen only the month and year are knownYYYYwhen only the year is knowncYYYYfor circa dates, such asc1976YYYY-YYYYfor date spanscYYYY-YYYYfor circa date spans_ndwhen there is no date at all
5. Zero-padding and sequencing
- Use zero-padding for sort order (
001, not1) - Use
pfor page numbers (p001) - Use
sfor scan numbers - If you may exceed 999 items, increase padding (
0001,0002, ...)
6. Length
Aim for fewer than 50 characters in the filename itself when possible. Remember Windows path limits include the full path, not just the filename.
7. Names and authors
Use last-name-first format:
doe-john
8. Consistency
Keep naming conventions consistent across the entire project.
Item ID Strings
The item ID string identifies the collection, series, subseries when applicable, and item number.
The prefix identifies the collecting area:
cameans Community Archivesmsmeans Manuscripts for non-VSU recordsuameans University Archives for Valdosta State records
The first prefix-number pair, such as ca-013, is the collection number. The next three-digit string is the series number. The next three-digit string is the subseries number when applicable. The final number is the item number.
Example item ID:
ca-013-001-002-001
PDF Filenames
PDF filenames should begin with the item ID, followed by a short item title, followed by the date when known.
Use this pattern:
item-id_short-title_date.pdf
The master PDF/A uses the base filename. The reduced-size access PDF usually uses the same filename with a added after the date.
Examples:
ca-013-001-002-001_hahira-gold-leaf_1973-01-04.pdf
ca-013-001-002-001_hahira-gold-leaf_1973-01-04a.pdf
If there is no date, use _nd for the master PDF/A and _nd_a for the access PDF.
Examples:
ca-013-001-002-001_hahira-gold-leaf_nd.pdf
ca-013-001-002-001_hahira-gold-leaf_nd_a.pdf
Truncate long titles enough to keep the filename readable while preserving the main identifying words.
Page Scan Filenames
Page scan filenames should use the item ID plus a page number.
Use this pattern:
item-id_p000.jp2
Example:
ca009-007-001_p001.jp2
Use enough zero-padding to keep files in the correct sort order.
Bag Filenames
The completed bag ZIP filename should identify the item and end with _bag.zip.
Example:
ca009-007-001_quitman-high-reunion_1996-06-08_bag.zip
