What Is Technical Data Extraction?
Technical data extraction turns datasheets, catalogs, drawings and certificates into structured, source-linked product attributes. The hard part is deciding which value belongs to which product.
Technical data extraction turns unstructured technical documents, datasheets, catalogs, exploded drawings and certificates, into structured, source-linked product attributes. The hard part isn’t reading the PDF; it’s deciding which extracted value belongs to which product and whether it can be trusted against what’s already recorded.
For industrial catalogs, the technical PDFs are often the real master data: the ERP row holds a short description, and the rated current, IP rating and certification sit in the datasheet. Extraction moves them into attributes. Claro attaches the document and location to every extracted value, so the attribute stays checkable.
Extraction vs resolution
Reading is not identity. A single breaker datasheet commonly lists the 10A, 13A and 16A versions in one table. Extraction produces three values; resolution decides which SKU each belongs to. Getting that wrong produces a value that is correctly extracted and wrongly attached, which is the same failure as the variant treated as a duplicate. The matching step is entity resolution.
Provenance per extracted field
Every extracted attribute should carry its source document, location and extraction time. That is data provenance at field level. It lets a reviewer open the page the value came from and lets the system re-check when the datasheet is revised.
Validation against the existing record
An extracted value is compared with what the record already holds. If they agree, the value becomes Known; if they conflict, the field is flagged as an evidence gap for review instead of being overwritten. Validated values are then written back to the ERP or PIM.

FAQ
What is technical data extraction?
Technical data extraction turns unstructured technical documents, such as datasheets, catalogs, exploded drawings and certificates, into structured, source-linked product attributes.
Is extraction the same as entity resolution?
No. Extraction reads values from a document. Resolution decides which product those values belong to. A datasheet often covers several variants, so a correctly read value can still be attached to the wrong product.
Why does each extracted value need provenance?
Each value should link to the document and page it came from, so it can be checked, compared with what is already recorded, and re-checked when the document is revised.
How do you know an extracted value can be trusted?
Compare it against what the record already holds. Agreement with an existing sourced value raises trust; a conflict becomes an evidence gap to be reviewed rather than silently overwritten.
