Introduction

ModelOp Center provides comprehensive versioning for all models under management, inclusive of versioning of all items that compose a model. For each version of a model, ModelOp Center takes a snapshot of all the elements that are part of the Standard Model Definition within ModelOp Center’s Production Model Inventory, such that you have long-term audibility and reproducibility.

Details

All of the elements of the Standard Model Definition are versioned using ModelOp Center’s Model Manager micro service, and for external artifacts (e.g. Model Source Code), are backed by your preferred enterprise-standard versioning tooling.

For example:

• Model Source Code → backed by Git (all git-compliant systems: Github, Bitbucket, Gitlab, etc.)

• Model Attachments → backed by standard artifact repositories (such as S3, Artifactory, etc.)

• Metadata & Other Elements → backed and versioned by ModelOp Center’s Model Manager

Model Snapshots

Behind the scenes, ModelOp Center’s data model creates a new model snapshot that is an immutable copy of all the elements (or references to the elements) that compose that model at a given point in time. These snapshots are persisted in perpetuity for long term auditability. For more details about the ModelOp Center metadata and data model, see Model Metadata Details.

To Create a New Model Snapshot

A new model version is created when a User “submits” a model for productionization. This can be done via the ModelOp Center UI or the Jupyter or RStudio plugins.

Create Version via the ModelOp Center UI

Create Version via the Jupyter Plugin

To create a new version via the Jupyter Plugin, please see the “Submit a Model” section of the Submit Model Version using Jupyter.

Create Version via the RStudio Plugin

To create a new version via the RStudio Plugin, please see the “Submit a Model” section of the Submit Model Version using RStudio.
