What are “Library metrics”?

Version 0.9.0 added a bunch of metrics about your PhotoStructure library to the about page.

This page tries to explain what exactly these numbers represent.

Tags 🔗

All tags in PhotoStructure are hierarchical: tags can have parent and children tags.

• The tag When/2020/Feb has a “parent” tag of When/2020.

• The tag When/2020 will have child tags for all the months that have photos or videos.

• A tag is considered a “leaf” if it has no child tags.

• When you see that a photo is tagged with When/2020/Feb, this means the photo is both associated to When/2020/Feb and to all ancestor tags, including When/2020.

The “tags” metric you see in the about page is the number of all leaf tags in your library.

Assets 🔗

The “assets” metric is the count of deduplicated photos and videos in your library.

This number will always be equal to or less than the sum of image and video files due to PhotoStructure’s de-duplication.

Image files 🔗

The “image files” metric is the count of distinct paths to images that your library is currently tracking.

If you opt for automatic organization, expect the sum of this number and the “video files” count to be at least 2x the number of assets in your library. This is due to each unique file being copied into your PhotoStructure library.

Video files 🔗

The “video files” metric is the count of distinct paths to videos that your library is tracking.
