What is ASAM ODS? ASAM ODS (Open Data Services) is the industry standard for test data management in automotive and engineering. Maintained by the Association for Standardization of Automation and Measuring Systems (ASAM), with participation from major OEMs and tool vendors, ASAM ODS defines three capabilities that together form the foundation of professional test data management.

ASAM ODS Base Model

First, ASAM ODS defines an ASAM ODS Base model that structures test data into meaningful categories. The ASAM ODS base model provides elements for describing projects, test objects (the unit under test), test environments (bench, facility, conditions), test procedures, and measurement results. The ASAM ODS data model transforms scattered files into searchable, comparable, governed data. An organization that adopts the ASAM ODS data model gains a shared vocabulary across departments, sites, and tools. Powertrain engineers, NVH engineers, and battery engineers all describe their tests using the same ASAM ODS structural framework, even though the signals they measure are different.

The ASAM ODS API

Second, ASAM ODS defines a standardized ASAM ODS API for accessing test data. In the current version (ASAM ODS 6.2), this is an HTTP/REST interface that any tool can connect to. Engineers access the same data from MATLAB, Python, web browsers, or custom applications without format conversion or vendor lock-in. The ASAM ODS API is what makes ASAM ODS a practical foundation for test data management rather than a theoretical specification. HighQSoft has been an active participant in shaping the ASAM ODS standard for over 25 years, contributing to its evolution from CORBA-based APIs in ODS 5 to the modern HTTP/REST interfaces in ODS 6.

ATFx File

Third, ASAM ODS defines file and transport formats (ATFx) for exchanging test data between systems. Data stored in one ASAM ODS system can be transferred to another ASAM ODS system without loss of structure or metadata, a capability that becomes critical when organizations need to share test data with suppliers, partners, or customers.

ASAM ODS Compare to File-Based Test Data Storage

How Does ASAM ODS Compare to File-Based Test Data Storage?

ASAM ODS-based test data management provides structured, governed access to engineering test data. File-based storage on network drives and folders lacks the structure, searchability, and governance that engineering organizations require at scale. The following comparison shows how ASAM ODS addresses the limitations of file-based test data storage.

File-Based Storage (Network Drives, Folders) ASAM ODS-Based Test Data Management Finding data Browse folders, guess filenames, ask colleagues Query by test object, date, conditions, project; results in seconds Tool access Export/import per tool; manual format conversion ASAM ODS standard API from MATLAB, Python, web, REST; no conversion needed Long-term retention Dependent on format readability and folder knowledge ASAM ODS standard interface ensures accessibility for 30+ years Compliance and audit Manual document assembly; lineage reconstructed after the fact Built-in access control, change tracking, data lineage Scalability Degrades as volume grows; search becomes impossible at petabyte scale HighQSoft's mixed-mode architecture scales metadata and mass data independently Cross-domain search Each domain is an island; no unified search One ASAM ODS data model across all test domains; federated access via HighQSoft's Janus Platform Vendor independence Locked to the tools that created the files Any ASAM ODS-compatible tool can read the data
Test Data Management as a Discipline

What Is Test Data Management as a Discipline?

ASAM ODS provides the foundation for test data management, but a standard alone does not constitute the discipline. The ASAM ODS standard defines how test data is structured and accessed. Test data management as a discipline defines the practices, governance, and automation that an organization builds on top of that ASAM ODS foundation.

Catalog Management

Catalog management ensures that signal names, units, and test procedures are consistent across all labs and departments. When a powertrain team in Munich and a durability team in Detroit both label engine speed as "n_engine" in RPM, their measurements become directly comparable. HighQSoft's Catalog Editor enforces these naming standards organization-wide.

Data lifecycle governance

Data lifecycle governance defines retention periods, access permissions, and archival rules. Battery test data for a vehicle program may require 15 years of retention for regulatory compliance, while prototype screening data can be archived after 3 years. Test data management assigns these policies at the data model level, not per folder or file share.

Standardized access interface

Standardized access interfaces let every stakeholder work with test data through the tool that fits their workflow. HighQSoft provides access through ASAMCommander (web portal), the ASAM ODS Toolbox (MATLAB), pyHQL (Python), REST APIs, and natural language queries through HighQSoft's MCP Server and Claire.

Analysis automation

Analysis automation transforms raw measurements into engineering insights at scale. Instead of an engineer manually running a MATLAB script on each test run, HighQSoft's Merlin Analysis Server executes thousands of analysis jobs daily, triggered automatically when new data arrives. Every result links back to its source data and analysis parameters, making the entire chain reproducible.

The organizations that get the most value from their test data are not simply those that adopted ASAM ODS. They are the ones that built a discipline around ASAM ODS: catalog management for consistency, governance for trust, automation for scale, and standardized interfaces for adoption. This is what separates organizations that store test data from those that manage test data.
