Overview
ISO/TS 22745-35:2010 is a technical specification for industrial automation and integration that defines how to query characteristic data in ISO 22745‑compliant master data. As a specialization of ISO/TS 29002-31, it provides a conceptual model in UML and a physical file format based on XML. The standard supports open technical dictionaries (OTDs) to enable consistent, machine-readable master data exchange across engineering, procurement, and maintenance systems.
Key Topics
- Scope and purpose: Requirements for constructing and executing queries against ISO 22745 master data repositories to retrieve characteristic (attribute) information.
- Conceptual model: Query structures and relationships described using Unified Modeling Language (UML) to promote a common understanding among implementers.
- Physical format: Query and response payloads expressed in an Extensible Markup Language (XML) file format for interoperable data exchange.
- Compliance: Requirements aligned with ISO 22745 conventions for open technical dictionaries and master data semantics.
- Interoperability focus: Emphasis on semantic consistency, unambiguous characteristic identification, and exchange-ready query definitions.
Applications
ISO/TS 22745-35:2010 is practical for organizations that need standardized querying of product and asset characteristics across systems:
- System integrators and automation vendors implementing data exchange between PLCs, SCADA, MES, ERP, PDM/PLM, and MDM systems.
- Data architects and catalog managers standardizing product attribute search, filtering, and selection in electronic catalogs and procurement platforms.
- Maintenance and engineering teams automating parts lookup, spare-parts management, and specification retrieval using machine-readable master data.
- Software developers building web services, APIs, or batch import/export tools that consume or produce ISO 22745-compliant characteristic queries and responses.
Benefits include improved data consistency, faster integration projects, reduced manual data reconciliation, and more effective reuse of master data across the enterprise supply chain.
Related Standards
- ISO/TS 29002-31 - Parent specification that ISO/TS 22745-35 specializes.
- ISO 22745 - The suite of standards on open technical dictionaries and their application to master data (general framework and conventions).
By adopting ISO/TS 22745-35:2010, organizations can standardize how characteristic data is requested and shared, enabling reliable machine-to-machine interoperability and better master data governance across industrial automation and enterprise systems.
