# Dataset Card: PartInventory
## Summary
PartInventory is a fine-grained hierarchical instance-segmentation dataset derived from **SPIN** (built on **PartImageNet**). It provides detailed part annotations and serves as a **proof of concept** for exploring new annotation workflows and more efficient storage formats for large-scale instance segmentation.

## Description
PartInventory refines SPIN annotations with more granular labels and updated hierarchies. It is intended to support research on part-level segmentation, hierarchical understanding, and efficient dataset representations (e.g., Parquet/Arrow).
This release is an early, **proof-of-concept** version. Further expansions are planned.
