Overview
IEC TR 62699-1:2014 - "Mapping rules and exchange methods for heterogeneous electronic parts libraries – Part 1: Building an integrated search system" defines a methodology to integrate and search electronic parts information that is distributed across heterogeneous, multi-national or multi-enterprise parts libraries. The technical report focuses on identification and classification of mapping types and on defining general and specific mapping rules to enable interoperable, extendable services such as integrated search and e‑sourcing across disparate parts databases.
Key points:
- Targets integration of heterogeneous parts classification and property systems.
- Enables deterministic search results where direct 1:1 correspondence does not exist (covers 1:1, 1:N, N:1 and 1:0/0:1 mapping cases).
- Excludes schematic library management and ongoing maintenance processes.
Key Topics and Requirements
- Application architecture & interoperability: Describes an interoperability system, data flow and sequence diagrams to support integrated services.
- Utilized dictionary format: Defines formats and rules for a common dictionary (UD_Class, root properties, property formats) to act as the integration pivot.
- Mapping types & classification: Identifies mapping scenarios (e.g., one-to-one, one-to-many, many-to-one, absent mappings) and provides classification guidance.
- Mapping rules: Specifies a general mapping model and concrete rules for each mapping type to produce consistent search and integration results.
- Interfaces & message formats: Defines information exchange patterns and message blocks (query/detail request/response, error/warning messages) for parts list and detailed part information exchange.
- Practical constraints: Clarifies out-of-scope elements (schematic definition/management and maintenance processes) so implementers focus on mapping and exchange.
Applications
IEC TR 62699-1 is practical for:
- Building integrated search systems and multinational e‑sourcing platforms that query multiple parts libraries in real time.
- Enabling cross-border procurement and supplier/distributor search where libraries use incompatible classifications.
- Integrating PLM/ERP/ECAD systems with multiple parts repositories through standardized mapping and message exchange.
Who should use this standard
- Software vendors and system integrators developing parts search, procurement, and catalog aggregation tools.
- OEMs, distributors and electronic component data managers needing multi-source parts integration.
- Standards bodies, national parts library custodians and technical committees focused on parts classification and interoperability.

- Other parts in the IEC 62699 series (see IEC catalog for the series).
- Drafting and publication follows ISO/IEC Directives (referenced in the TR foreword).
