wtf is om-core?

This project is a modeling engine that aims to replace the way people build financial and operational models in spreadsheets. Instead of storing a model as a grid of cells, formulas, and copied tabs, it represents the model using business concepts like dimensions, cubes, groups, and rules, and treats spreadsheet style grids as just one way of viewing that underlying model. The idea is that in a normal spreadsheet, business logic, layout, and calculation all get tangled together in individual cell references, which makes large models fragile and hard to audit as they grow. Here, dimensions describe business axes such as Time, Account, Region, or Product, cubes hold the actual data across those dimensions, groups organize related items into hierarchies, and rules describe calculations in terms of these business concepts rather than specific rows and columns. For example, a rule could state that gross margin comes from revenue minus cost, without tying that logic to a particular spreadsheet cell. The project ships as a full application you run from source, including a graphical interface, a text based terminal interface, a command line shell, and a headless mode for automated runs, all built on a shared Python based engine. A simple script language lets you define dimensions, cubes, views, and rules directly, then calculate the results. Installation uses the uv Python tool and works on Linux, macOS, and Windows through provided start scripts. The project is explicitly alpha software: its commands, file formats, and internal interfaces may still change before a stable 1.0 release, and it is not yet meant for critical business use without independent checking. It is released under the GNU Affero General Public License version 3, a copyleft license, with the OM Core name itself governed by a separate trademark policy.
