# Versions

Version history of the OpenG2P Master Data Service (MDS).

MDS source code, Docker images, and the Helm chart all live in the single repository [`master-data-service`](https://github.com/OpenG2P/master-data-service). On the `develop` branch the published chart version is `0.0.0-develop.<run-number>` and Docker images are tagged `develop`. Tagged releases carry semantic versions on both the git tag and the published artefacts.

Images publish to Docker Hub (`openg2p/master-data-api`, `openg2p/master-data-ui`, `openg2p/master-data-db-seed`) and the chart to [`openg2p-helm`](https://openg2p.github.io/openg2p-helm).

The **Last Modified** date for in-progress (`develop` / `0.0.0-develop.N`) versions is updated as work continues. Released versions carry the date of their git tag.

MDS is deployed through the **`commons-services`** umbrella chart, not as a standalone install. The version pinned there is what an environment actually runs — see [Deployment](/platform/platform-services/master-data-service.md#deployment).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.openg2p.org/platform/platform-services/master-data-service/versions.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
