The standards the finished document is measured against
Ask for the finished document to be measured against a standard, and get what stands in its way back beside the file.
Summary
Claiming a standard and holding to it are two different things. This asks for the document that comes out to be read again, clause by clause, against the standards you name — and what stands in the way comes back beside the file. A document need not claim a standard to be measured against it: it is the way to find out what it would take.
Technically
Written at the top level of a request, under
"check"
check names the standards the finished document is measured against, the findings coming back in the answer beside the file. Reading every clause of a standard costs time, so nothing is measured until it is asked for: an empty list measures nothing. The values are pdfa3b, pdfa3a, pdfa4, pdfa4f, pdfua1, pdfua2 and pdfx4.
Request schema
-
check— array of strings, optional, empty by default. -
pdfa3b— ISO 19005-3 level B.pdfa3a— the same part at level A, which asks for the structure as well. -
pdfa4— ISO 19005-4.pdfa4f— the same part, at the level that carries files of any kind. -
pdfua1— ISO 14289-1.pdfua2— ISO 14289-2. -
pdfx4— ISO 15930-7.
Measuring is not claiming: what a document says it is comes from archive, accessible and print. A document measured against a standard it never claimed still comes back with the file.
