However, a substantial proportion of existing test and product data resides in formats that were never designed for automated processing: PDF data sheets, proprietary Excel templates, laboratory reports in unstructured text, and isolated database exports with heterogeneous schemas. When organisations seek to adopt new data standards—such as VDA 231-301 or comparable structured data models—they inevitably face the challenge of converting these legacy data inventories into the target format. In practice, this conversion process is one of the most resource-intensive steps in any digitalisation initiative. Typical obstacles include: - Inconsistent document structures across suppliers, projects, and time periods - Ambiguous or incomplete descriptions of testing conditions and parameters - Implicit domain knowledge embedded in naming conventions and abbreviations - Varying granularity of recorded results, from aggregated summaries to raw measurement values - Absence of unique identifiers linking test results to defined testing requirements The cumulative effect is a significant bottleneck: organisations cannot leverage their historical data assets within modern, interoperable systems without first undertaking a costly and error-prone transformation effort. This delays the realisation of efficiency gains that standardised data models are designed to deliver. #### AI and Algorithmic Mapping: Potential and Limitations A widely discussed approach to legacy data conversion involves the use of Artificial Intelligence and algorithmic methods to automatically map existing data into a target data model. Techniques such as natural language processing, pattern recognition, and rule-based extraction engines can identify and classify testing requirements, extract parameter values, and propose mappings to standardised fields. These methods offer clear advantages in terms of throughput and scalability. For large document volumes, automated approaches can process orders of magnitude more data than manual review. However, purely automated solutions encounter well-documented limitations in the materials testing domain: - Normative texts and OEM specifications frequently contain ambiguous formulations that require domain expertise to interpret correctly - Variations in document layout, terminology, and language across suppliers and time periods reduce the reliability of pattern-based extraction - Customer-specific parameterisations and non-standard testing conditions are often documented in ways that resist automated classification - Errors in automated mapping—particularly false-positive assignments—can propagate through downstream systems and compromise data integrity - Confidence in the output diminishes when the source data deviates from the formats and structures on which the models were trained As a result, relying exclusively on AI or algorithmic approaches introduces risks that are difficult to accept in quality-critical environments. The automotive industry, in particular, demands traceability, auditability, and correctness—requirements that purely automated pipelines cannot consistently guarantee without additional safeguards. #### Brain of Materials: A Hybrid Approach to Reliable Legacy Data Conversion Brain of Materials addresses the fundamental tension between automation efficiency and domain reliability by researching and implementing multiple complementary approaches for the extraction and standardisation of legacy data. Rather than relying on a single method, the platform employs a hybrid strategy that combines algorithmic processing with structured domain validation. The core methodology integrates: - AI-based text and structural analysis for the automated detection and classification of testing requirements within heterogeneous source documents - Algorithmic extraction engines that identify parameter values, testing conditions, and result structures from legacy formats including PDF data sheets, Excel files, and proprietary templates - Rule-based mapping logic that assigns extracted data elements to the appropriate fields within target data models such as VDA 231-301 - Systematic assignment of unique TestIDs (TIDs) to each identified testing requirement, ensuring unambiguous referencing and eliminating interpretative leeway - Domain-specific validation through continuous feedback loops with subject matter experts, ensuring that automated suggestions are verified against established technical knowledge This hybrid approach—combining algorithmic evaluation with expert-guided quality assurance—ensures that even extensive, heterogeneous legacy data inventories can be transformed into a structured, standardised data basis with a high degree of reliability. The feedback mechanisms simultaneously serve to refine and optimise the underlying algorithms, improving extraction accuracy over successive iterations. #### Enabling Digitalisation of Existing Systems and Processes The ability to reliably convert legacy data into standardised formats unlocks a range of operational benefits that extend well beyond the immediate conversion task. By transforming historically accumulated document repositories into a consistent, interoperable data source, organisations establish the preconditions for meaningful digitalisation of their entire materials quality assurance landscape. Concrete applications include: - Digitalisation of existing systems: Legacy test and product data becomes accessible within modern CAQ, PLM, and ERP platforms, enabling organisations to integrate historical data into current digital workflows without rebuilding their data foundations from scratch - Accessibility for new formats and standards: Data originally captured in obsolete or proprietary formats is made available in standardised, machine-readable structures—such as VDA 231-301—facilitating cross-system processing and automated validation - Simplification of process digitalisation: With a structured, standardised data basis in place, subsequent digitalisation steps—from automated result comparison to cross-supplier benchmarking to audit-proof documentation—become significantly more efficient and scalable - Cost-effective standardisation: By combining automated extraction with targeted expert validation, the conversion effort per data record is reduced substantially compared to fully manual approaches, making standardisation economically viable evenvfor large legacy inventories - Preservation of institutional knowledge: Testing data and associated metadata that might otherwise be lost due to format obsolescence or organisational changes are systematically captured in a durable, interoperable form   #### Enabling Digitalisation of Existing Systems and Processes The conversion of legacy data gains particular significance in the context of industry-wide standardisation efforts. VDA 231-301 defines a generic, machine-readable data model for the structured description of testing requirements, testing conditions, result structures, and references to standards and specifications. However, the value of such a standard is fully realised only when existing data—not merely newly generated data—can be represented within it. Brain of Materials facilitates this integration by mapping extracted legacy data directly into the VDA 231-301 data model and enriching it with TestIDs. The TestID provides a unique, machine-readable identifier for each testing requirement, including its methodology, parameterisation, and conditions. Within the VDA 231-301 framework, the TestID functions as a BusinessKey that enhances the data model with unambiguous references—bridging the gap between normative text and operational testing practice. This combination of standardised data structures and unique identification transforms legacy data from a static archive into an active, queryable, and automatable resource within the digital supply chain. #### Summary The conversion of existing test and product data into new data standards and data models is one of the most significant practical challenges in the digitalisation of materials quality assurance. Purely manual conversion is prohibitively expensive at scale; purely automated approaches lack the domain-specific reliability required in quality-critical environments. Brain of Materials addresses this challenge by researching and implementing a hybrid methodology that combines AI-based extraction, algorithmic mapping, and expert-validated structuring. This enables: - Cost-effective and reliable standardisation of legacy data inventories - Digitalisation of existing systems by making historical data accessible in modern formats - Seamless integration with standardised data models such as VDA 231-301 - Unambiguous identification of testing requirements through systematic TestID assignment mechanisms - Continuous improvement of extraction accuracy through adaptive feedback mechanisms Organisations that address their legacy data challenge systematically will not only accelerate their transition to data-driven quality assurance but also unlock the full value of their historical data assets for future digitalisation initiatives. #### Curious?
