The most advanced technical data pipeline

From raw PDF datasheets to structured, queryable datasets — our end-to-end pipeline handles the full complexity of technical documentation.

EVAHub data pipeline — from raw PDFs to structured JSON

From raw docs to structured data

01
Ingest

PDFs, scanned docs, HTML pages, XML feeds — any format, any manufacturer.

02
Structure

AI extracts parametric specs, classifications, and compliance data.

03
Enrich

Ontology mapping, cross-references, unit normalization, quality scoring.

04
Distribute

REST/GraphQL API, batch exports, real-time webhooks — your format.

Step 01

Ingestion Engine

Our pipeline accepts any format of technical documentation. We handle the complexity so you don't have to.

PDF / Multi-page PDFs
Scanned Documents
HTML / Web Pages
Spreadsheets (XLS, CSV)
Word Documents
XML / JSON feeds
Multi-language support — Documents in English, Spanish, German, French, Chinese, Japanese
Batch processing — Upload thousands of documents at once via API or SFTP
Continuous monitoring — Auto-detect new versions from manufacturer websites
Step 02

AI Structuring

Domain-trained AI models extract structured data from complex technical documents with precision that generic OCR cannot achieve.

Table Extraction

Complex multi-row, multi-column spec tables with merged cells and nested headers

Parameter Identification

Voltage, temperature range, dimensions, certifications — extracted and typed

Graph & Curve Parsing

Performance curves, derating graphs, frequency responses digitized into data points

Relationship Mapping

Cross-references between products, compatibility matrices, alternatives

Step 03

Ontology & Enrichment

Raw extracted data becomes rich, interconnected knowledge through our classification taxonomy and enrichment pipeline.

Ontology Classification

Hierarchical taxonomy with categories, subcategories, and product families

Cross-Referencing

Links between related products, compatible accessories, and replacement parts

Metadata Tagging

Manufacturer, brand, compliance flags, lifecycle status, availability

Compliance Mapping

CE, UL, RoHS, REACH, FCC — automatically flagged and structured

Step 04

Distribution & Access

Access your structured data however you need it — through our API, bulk exports, or custom integrations.

REST & GraphQL API

Query structured data programmatically with filtering, pagination, full-text search, and field-level access

Bulk Exports

Download datasets in JSON, CSV, or Parquet format for offline processing and model training

Real-time Sync

Webhook notifications when new data is available or existing data is updated. Delta updates included

Provenance Chain

Full data lineage — source document, extraction date, verification status. EU AI Act compliant

Every data point is verified

We combine AI extraction with human-in-the-loop verification to ensure precision-grade data quality.
