Class PdfA12Validator

java.lang.Object
org.projecthusky.validation.service.pdf.PdfA12Validator
@ThreadSafe public class PdfA12Validator extends Object
Validator of PDF documents to conformance level A-1 and A-2.

In the CH-EPR project, CDA-CH-EMED and CH-EMED, PDFs must conform to the level A-1 or A-2.

The following PDF levels are passing:

  • PDF/A-1b – PDF 1.4 – Level B (basic) conformance
  • PDF/A-1a – PDF 1.4 – Level A (accessible) conformance
  • PDF/A-2b – PDF 1.7 – Level B (basic) conformance
  • PDF/A-2a – PDF 1.7 – Level A (accessible) conformance
  • PDF/A-2u – PDF 1.7 – Level U (unicode) conformance

The VeraPDF parser and validator seem to be thread safe as of version 1.12, see is veraPDF Processor API thread safe: this means that one can safely use the the API in multiple parallel threads assuming that each thread processes a single PDF document at a time.
