## What it is
BIMserver is an open-source, model-driven server platform for storing, managing, and querying Building Information Modeling (BIM) data in the IFC standard. Unlike a file server, it stores IFC data as objects, enabling querying, merging, filtering, versioning, model checking, and multi-user collaboration with real-time updates and notifications.

## Use cases
- store and manage IFC models for a construction project
- query and filter BIM models programmatically
- merge multiple IFC models into one
- track revisions and versions of building models
- check BIM models for errors and rule violations
- enable multi-user collaboration on a shared building dataset
- build custom BIM applications on top of an IFC database
- generate IFC files on the fly from stored model data

## When to choose
- you need a central, multi-user server for IFC/BIM data rather than simple file storage
- you want to query, merge, or filter IFC models at the object level
- you are a developer building BIM applications or bim-bots on an open platform
- you need model versioning, revision history, and update notifications for building data
- you want an open-source, self-hosted alternative built on the open IFC standard

## When to avoid
- you only need to view or share IFC files without querying or collaboration features
- your project does not involve building/construction data or the IFC standard
- you need a lightweight file server or document management system
- you cannot comply with the AGPL-3.0 license in your usage
- you need a turnkey end-user desktop BIM viewer rather than a server platform
