Application and Purpose

The ReqIF Server provides interactive and programmatic access to requirements and specification data in general.

The ReqIF Server is designed to process data according to the RIF and ReqIF standards as pub­lished by ProSTEP iViP and OMG respectively. RIF/ReqIF input data is an XML file representing system specifications or requirements, including both type definition (data model) and content (user data). Mirroring the data model and the user data, the ReqIF Server provides trans­actions for multi-user and integrated appli­cation environ­ments - without further preparation.

Specification objects, e.g. system components and requirements, are made available both via inter­active views and via self-describing web-­services. Views is intended for interactive users, whereas the web-­services offer create, read, update and delete transactions for system integration. The data model, for example the hierarchical ordering of objects or the rela­tions between objects, is reflected in the interfaces to allow for easy navigation.

Since the RIF/ReqIF meta-model is much more versatile than for requirements and system specifications alone, the ReqIF Server can host a wide range of applications, such as trans­actional Informa­tion Desks or Directories. Essentially, the ReqIF Server is an enterprise level transaction system with

  • a dynamic object-relational data model,
  • temporal objects for retrieving any historical revision and
  • a role model and fine-grained access control.
