The specification and implementation of data related to heterogeneous resources are still actual problems in industrial systems in spite of the variety of data storage models and technologies available on the market today. And this is because industrial resources have associated proprietary specifications and implementations for their related data. The paper proposes two possible solutions to these problems. The first specifies a Distributed Repository Model that aims at providing a unified/common view of the heterogeneous resources in an industrial system. This approach makes use of the ISO 10303 standard. The second proposes the definition of an industrial-specific language that provides the syntax and the rules to create logical data models for industrial systems. It is based on the eXtensible Markup Language. Both approaches are independent of any implementation detail and/or storage-model architecture. A comparison of the two solutions is provided at the end of the paper.
