Ohjelmitta

Ohjelmitta is a Finnish software framework designed to provide developers with a modular architecture for building business applications. It was first released in 2012 by a consortium of Finnish academic institutions and commercial partners. The name derives from the Finnish word ohjelma, meaning "program," combined with the suffix -tina, which in Finnish can indicate a tool or instrument, suggesting that the framework functions as a tool for constructing programs.

The core concept behind Ohjelmitta is the separation of concerns via a layered approach. At the base layer developers use the included toolkit of reusable components—such as data access modules, user interface controls, and authentication services—written in the Java programming language. The middle layer exposes a service-oriented architecture that allows modules to communicate through standardized RESTful APIs. The top layer is a domain-specific language that enables developers to define business rules without writing Java code directly. This makes it particularly suitable for rapid application development in sectors such as public administration, healthcare, and finance, where regulatory compliance and auditability are essential.

Ohjelmitta is distributed under an open‑source license (GNU GPL v3) and is actively maintained through a community-driven model. Its source code repository resides on GitHub, and the project hosts extensive documentation, example projects, and a community forum. The framework has been adopted by several municipalities in Finland to build citizen‑facing services, and it has also seen use in academic research projects focused on process automation and digital governance.
