The article describes the structure of the ontology of specification patterns from the texts of technical documentation. This ontology combines patterns of known classifications of requirements with new patterns. The ontology allows the recording of Boolean pattern combinations of the following types: qualitative, real and branching time, with combined events, quantitative characteristics of events and patterns, and simple statements about the data. Examples of the requirement patterns for the real vacuum control system of the Large Solar Vacuum Telescope are given. The scheme of intellectual support system for formal verification of distributed program systems is outlined.
