Design a Tag Vocabulary for Your Reference Library

A useful taxonomy starts with the questions you ask while working. Write down a few recent searches: hands holding an object, stone in rain, a low camera angle, or a restrained palette. Those questions are better starting points than an exhaustive list of art terms.

Separate the dimensions

These are example labels. Avoid applying them mechanically to every image. A term that is irrelevant to your work adds maintenance without improving retrieval. For missing sources or creators, a no:source or no:creator search, or a Review of the Uncredited queue, can replace a status tag.

Define ambiguous words

Write a short definition for terms that could drift. Does "favorite" mean beautiful, useful for study, or approved for a client? If those meanings matter separately, use separate fields or labels. In refern, a tag can hold named links, such as a link to the note where you wrote its definition.

Choose a preferred spelling and a single term for close synonyms. Keep the distinction when two terms answer different questions, such as portrait and face-detail. In refern, keep one tag and add the other spellings as aliases; search, Quick Tags, and the Tag Manager still find the tag by any alias.

Pilot the vocabulary

Tag a small representative selection from different sources. Try the searches you wrote at the start. Inspect both the images found and the ones you expected but missed.

If the vocabulary produces a huge result for every question, add a more useful distinction. If each tag has one image and you cannot remember its name, simplify it. There is no universal ideal number of tags per image.

Implement it in refern

Use the tag manager to organize the terms and the metadata or Quick Tags controls to apply them. To apply a vocabulary in bulk from a script, see automating your library with the Local API. Current bulk editing shows shared and partial tags so you can change one term without erasing unrelated per-image tags. Categories group tags so they are easy to find; opening a category never adds its tags to items.

Create a preset only for a combination you repeatedly apply together. Verify it on a sample. A preset saves interaction, but can also repeat a mistaken assumption across many files.

Maintain with real usage

When retiring a tag, inspect its results and move the intended meaning to the replacement before deleting the old term. In the Tag Manager, Merge replaces the old tag with the new one on every item and then deletes the old tag; a merge cannot be undone. To rename several tags at once, select them and choose Add prefix, Add suffix, or Replace; the Tag Manager previews the new names before you click Rename, and unlike a merge, a rename can be undone. Needs attention lists likely duplicates, such as names that differ only by case or a simple plural. Keep source and creator records separate from thematic tags. To find items the vocabulary has not reached, sort with sort:tags-asc or start a Review in the Fewest tags first order.

Record the vocabulary's purpose in your own notes so a later cleanup does not change every rating or status label's meaning. Include workspace data in backups because refern tags are not automatically written into the source pixels.
