Using XML schemas to structure information models of capital construction facilities

Introduction. Building Information Modeling (BIM) is an auspicious approach that supports management and exchange of semantically rich 3D models across design disciplines. Recently, BIM has gained widespread acceptance in the AEC industry, and it improves the efficiency and quality of the process by facilitating the early exchange of 3D building models. At different stages of the life cycle, a building information model is gradually refined from rough conceptual design to detailed individual components. The task is to develop mechanisms for machine verification (authentication) of data transmitted to/from different systems (for example, from a customer to an expert evaluation authority, from a contractor to the urban planning management information system or any other state information system) in the form of an information model of capital construction facilities or certain components of an information model. Materials and methods. To substantiate the choice of the language employed to describe machine-readable documents, various use cases of XML schemas were analyzed, including the use of the Google Trends tool. Information systems, implemented in the Russian Federation, were also considered. Most of them use the W3C XML Schema language to describe XSD schemas. Results. A consolidated list of XML schemas, necessary and sufficient to maintain stages of the life cycle of a capital construction facility in terms of interaction with the Urban Planning Management Information System is presented. To ensure interaction between the life cycle participants and state information systems, it is necessary to have the list of XML schemas approved at the federal level. The paper presents matrixes of scenarios for the application of XML schemas in the following coordinates: participants, life cycle stages. Conclusions. XML schemas can be supplemented in respect of various stages of a life cycle of a capital construction faci-lity to be verified with due regard for further methodological approaches and changes in regulatory and technical acts; new approaches and the need for this supplementation must be substantiated.
