Product versions - Python SDK - Poelis

A product has one working copy and a history of published snapshots. Point calculations at a snapshot when the inputs need to stay still.

draft is the mutable working version
v1, v2, v3, … are immutable published snapshots
baseline is a pointer to one published version. Teams can move which version is marked baseline

prod = poelis.demo_workspace.demo_product

List versions

versions = prod.list_product_versions().names
print(versions)

Open draft, baseline, or a version number

draft = prod.draft
baseline = prod.baseline
v3 = prod.v3  # if it exists

Open a version by title

Named versions use the title, for example PROD 2025:

prod_2025 = prod.get_version("PROD 2025")

For reproducible results, read a specific version such as prod.v12, or prod.baseline when your process treats baseline as the current approved snapshot.

From any of these objects you can keep browsing items and properties the same way as on Browse your data. Writes are limited to the draft. See Edit properties.
