[veraPDF-users] How veraPDF performs XMP packets validation?
by Francesco Pretto 10 Jun '22

10 Jun '22

Hello veraPDF users/devs, I have a question over XMP packets validation in PDF documents: how does veraPDF actually does it? Can you point me to references in the code where this is performed? I elaborate more on the question, providing a viable solution as suggested by ISO standards committee. I have access to both ISO 16684-1:2019[1] and ISO 16684-2:2014[2]: the first standard generically describes the XMP packets data model and properties, explaining the many alternative notations accepted (that make difficult to validate the packets). The second suggests a method for the normalization of the packets to create an unique representation of the information stored in the packets (this method can be mostly implemented without knowing anything about the actual XMP data model/properties). It then supplies some sample RELAX NG schemas to validate unspecified XMP demo packets. These schemas clearly aren't describing the full schema to validate the XMP packets of PDF documents since all pdf specific properties are missing but also some generic ones. If the full schema to validate XMP packets in PDF documents was publicly available, validate the XMP packets in PDF documents would be quite simple as the normalization algorithm is not very difficult to implement. I asked for it in[3] but I doubt Adobe will release it. It may also not exist at all since 16684-2:2014 recommendations may have been developed independently from use in any actual Adobe product. Thank you in advance for any insight. Regards, Francesco [1] https://www.iso.org/standard/75163.html [2] https://www.iso.org/standard/57422.html [3] https://github.com/adobe/xmp-docs/issues/20

[veraPDF-users] veraPDF 1.14 onwards accepts file as PDF/A-1b compliant despite violation of clause 6.1.12 (floating-point range of ±32767.0)?
by Thomas Fischer 14 Apr '22

14 Apr '22

Hello, I have a PDF document that, depending on veraPDF version, either passes or fails conformance checks for PDF/A-1b. The file is publicly available being a doctoral dissertation: http://uu.diva-portal.org/smash/record.jsf?pid=diva2%3A280958&dswid=836 http://uu.diva-portal.org/smash/get/diva2:280958/FULLTEXT02.pdf With veraPDF 1.14.8 and later, this file passes the conformance check for PDF/A-1b, but it fails with veraPDF 1.12.1 and earlier with the following error message: <validationReport profileName="PDF/A-1B validation profile" statement="PDF file is not compliant with Validation Profile requirements." isCompliant="false"> <details passedRules="102" failedRules="1" passedChecks="65345" failedChecks="1"> <rule specification="ISO 19005-1:2005" clause="6.1.12" testNumber="2" status="failed" passedChecks="0" failedChecks="1"> <description>Absolute real value must be less than or equal to 32767.0</description> <object>CosReal</object> <test>(realValue >= -32767.0) && (realValue <= 32767.0)</test> <check status="failed"> <context>root/document[0]/OpenAction[0](156 0 obj PDGoToAction)/D[0]</context> </check> </rule> </details> </validationReport> Release details for core, validation model and gui are all 1.12.1 In contrast, for example, veraPDF 1.18.6 prints: <report> <buildInformation> <releaseDetails id="core" version="1.18.11" buildDate="2021-04-19T10:21:00+02:00"></releaseDetails> <releaseDetails id="validation-model" version="1.18.8" buildDate="2021-04-19T10:35:00+02:00"></releaseDetails> <releaseDetails id="gui" version="1.18.6" buildDate="2021-04-27T08:53:00+02:00"></releaseDetails> </buildInformation> <jobs> <job> <item size="4458678"> <name>/tmp/pdf/oaiDiVAorguu-111393.pdf</name> </item> <validationReport profileName="PDF/A-1B validation profile" statement="PDF file is compliant with Validation Profile requirements." isCompliant="true"> <details passedRules="101" failedRules="0" passedChecks="65346" failedChecks="0"></details> </validationReport> <duration start="1649428145077" finish="1649428146991">00:00:01.914</duration> </job> </jobs> <batchSummary totalJobs="1" failedToParse="0" encrypted="0"> <validationReports compliant="1" nonCompliant="0" failedJobs="0">1</validationReports> <featureReports failedJobs="0">0</featureReports> <repairReports failedJobs="0">0</repairReports> <duration start="1649428144942" finish="1649428147026">00:00:02.084</duration> </batchSummary> </report> I checked veraPDF-validation-profiles/PDF_A/PDFA-1B.xml and its Git history, but I could not identify any changes to the rules checking floating-point numbers for its range of ±32767 from Table C.1 of Adobe's PDF 1.4 specification. I used qpdf to extract more information on object 156 where I get the following output: $ qpdf --json --json-key=objects FULLTEXT02.pdf | grep -A 5 '"156 0 R": {' "156 0 R": { "/D": [ "158 0 R", "/FitH", -32768 ], So, to my understanding, the numeric value of -32768 is outside of the allowed range and thus veraPDF should reject this PDF file as *not* conforming to PDF/A-1b. Is there a bug in veraPDF or do I miss something? Thank you! Bye, Thomas

[veraPDF-users] Info on Release of verapdf-greenfield-2.0.59-installer.zip
by thirumani t 17 Jun '21

17 Jun '21

Hi Team, We are using the verapdf tool for checking PDFA compliance. Currently we are using version 1.12.1 and that reports the below error. While analyzing we noticed that this error is not being reported in the latest development version 2.0.59. So we are wondering if this is being reported incorrectly in the version 1.12.1 and has been fixed in the latest development version. Can you confirm if that is the case and also let us know if there is any tentative timeline on when you are planning to release the next version and will that be as that of a build after version 2.0.59? 6.2.11.8-1 - A PDF/A-2 compliant document shall not contain a reference to the .notdef glyph from any of the text showing operators, regardless of text rendering mode, in any content stream Thanks & Regards, Thirumani

[veraPDF-users] PDF/A-1b-validation - Vera visavi PDFTools
by Bo Öberg 30 Apr '20

30 Apr '20

Hi, We have a situation where a PDF/A-1b generated by PDFTools fails in VeraPDF validation. We need to find the problem to be able to use VeraPDF as a trustworthy validator! The VeraPDF "ValidationResult" is as follows: ValidationResult [flavour=1b, totalAssertions=6096003, assertions=[TestAssertion [ruleId=RuleId [specification=ISO 19005-1:2005, clause=6.2.3, testNumber=4], status=failed, message=If an uncalibrated colour space is used in a file then that file shall contain a PDF/A-1 OutputIntent, as defined in 6.2.2, location=Location [level=CosDocument, context=root/document[0]/pages[234](256 0 obj PDPage)/contentStream[0](4695 0 obj PDContentStream)/operators[1040]/xObject[0](4696 0 obj PDXForm)/contentStream[0](4696 0 obj PDContentStream)/operators[6137]/fillCS[0](1157 0 obj PDTilingPattern)/contentStream[0](1157 0 obj PDContentStream)/operators[15]/strokeCS[0]]]], isCompliant=false] The response from PDFTools on looking at the generated document and the Vera-response is as follows: "I can reproduce the behavior and have analyzed the exact error message returned by veraPDF. I can confirm, that the message is not correct. veraPDF complains, that "an uncalibrated colour space is used". However, the respective tiling pattern is an uncolored pattern, so it does not define any colors. The latest version of Adobe Acrobat (Preflight - my note) also validates the file successfully." Can any one tip me how to proceed? Is the response from PDFTools valid? In that case, how to fix VERA validation? We are using jar-files from Vera of version 1.14.105 (except for pdf-model-parser 1.14.103 and parser-1.14.104). I also include the actual pdf-file and the docx source file. Sincerely, Bosse

[veraPDF-users] value type for /AF entry
by Pablo Rodriguez 17 Mar '19

17 Mar '19

Dear list, validating a PDF/A-3 document with an attachment, the latest development version of veraPDF complains of missing /AF reference in /Catalog, /Page or similar element. I found https://www.pdfa.org/wp-content/uploads/2018/10/PDF20_AN002-AF.pdf. But in order to report the issue to the PDF creation tool, I need to know for sure which is the value type and the value of the /AF entry. I guess it should be an array of one or multiple /EmbeddedFile object references, such as in: /AF [8 0 R 10 0 R 40 0 R] Could anyone confirm this? Many thanks for your help, Pablo -- http://www.ousia.tk

[veraPDF-users] HTML report in Command Line Interface
by Pavlásková Eliška 15 Mar '19

15 Mar '19

Dear all, I would like to ask you for advice with VeraPDF command line interface. My institution (Charles University) use Vera as a validator of students' thesis. Students are supposed to submit thesis in PDF/A format and pass validation test based on our custom profile. In case of failure they get a VeraPDF xml report. Problem is that XML report is not very user-friendly. We would like to use HTML report with links to validation rules wiki, but it doesn't seem to be possible from CLI. Is there any solution of this? Has anyone tried to use html report from CLI? Thank you in advance Eliška Pavlásková

Hello, everyone, We've noticed possible issues with veraPDF's treatment of the following files from the Isartor test suite (in 1B mode): E:\PDFTest\PDFA\PDFA-1b\Bavaria testsuite\conforming\Real world\braun_feudel.pdf E:\PDFTest\PDFA\PDFA-1b\Bavaria testsuite\nonconforming\PDFA\apogee.pdf For the first file, the '-32768' in obj 336 is treated as a Real, even though it lacks a decimal point. For the second file, obj 164 is treated as a Metadata object and therefore fails due to the presence of a 'Filter' key inside it, even though it lacks the required 'Type Metadata' entry inside it and is therefore technically not a Metadata object stream dictionary. Please provide us with explanations and/or fixes. Thanks, Rastko at PDFTron Systems Inc.

[veraPDF-users] validation rule 6.8-4
by Pablo Rodriguez 27 Mar '18

27 Mar '18

Dear list, I have a PDF/A-3a file which veraPDF complains that it violates rule 6.8-4 (https://github.com/veraPDF/veraPDF-validation-profiles/wiki/PDFA-Parts-2-an…). I’m afraid there is no text in the wiki for that rule. Would it be possible that this text could be added? Many thanks for your help, Pablo -- http://www.ousia.tk

[veraPDF-users] document breaking rule 6.4.3-1
by Pablo Rodriguez 21 Mar '18

21 Mar '18

Dear list, I attach a PDF/A-3 document that veraPDF-1.15.1 detects as breaking the rule 6.4.3-1. The extended information shows the following (edited for legibility): PDSignature doesByteRangeCoverEntireDocument == true root/document[0]/AcroForm[0]/formFields[0](7 0 obj PDSignatureField)/V[0](1 0 obj PDSignature) Does the info above mean that the object 7 in the PDF document isn’t included in the signature byte range? Many thanks for your help, Pablo -- http://www.ousia.tk

[veraPDF-users] plugin deployment
by Jochen Staerk 14 Feb '18

14 Feb '18

Hi, I just release a new preview of my planned VeraPDF plugin (on https://github.com/ZUGFeRD/ZUV/releases/tag/v0.4.1) and unfortunately in the past months a) the need for ph-schematron has been confirmed and b) I could not solve the deployment issues. It turned out I do need ph-schematron, which in turn references saxon, for for performance issues: we're talking about 11 seconds (ZUGFeRD 1) respectively 4 seconds run time per ZUGFeRD file with when checking with XSLT2 (i.e. ph-schematron and saxon2) while it takes 11 *minutes* for a check without, i.e. with java's XSLT1. And so far I could not even produce a XSLT1 for the ZF2 (more precisely UN/CEFACT SCRDM CII 16B EN 16931) schematron. Despite something like java -jar ZUV-0.4.1-SNAPSHOT.jar -f <any ZUGFeRD PDF file like from http://www.mustangproject.org/MustangGnuaccountingBeispielRE-20170509_505.p…> works, if one tries to use the (shaded) ZUV-0.4.1-SNAPSHOT.jar as VeraPDF plugin there will be exceptions like Feb 12, 2018 10:36:31 AM org.verapdf.processor.ProcessorImpl extractFeatures WARNUNG: Exception caught when extracting features of item java.lang.NoClassDefFoundError: org/junit/rules/ExternalResource Does anybody have an idea how this could be solved? I e.g. tried a shaded jar with relocations but that did not work because saxon had to be be refered by it's original name which AFAIK is taken by VeraPDF internal usage. My only remaining straw would be turning the thing around and attempting to embed VeraPDF in the ZUGFeRD validator instead of embedding the ZUGFeRD validator in VeraPDF as a plugin. thanks a lot and kind regards, Jochen Mustangproject.org Chief ZUGFeRD amatuer

[Users] veraPDF and thread-safeness?
by Tony Schaller 09 Feb '18

09 Feb '18

Hi We have integrated veraPDF validation-model 1.8.1 from the maven repo (https://mvnrepository.com/artifact/org.verapdf/validation-model) into the eHealth Connector Open Source project (see https://sourceforge.net/projects/ehealthconnector/). See https://sourceforge.net/p/ehealthconnector/wiki/CDA%20Validation/ for more information. The eHealth Connector supports multithreading, but veraPDF seems not currently to be thread-safe. Is there any plan for a thread-safe veraPDF validation-model? Thanks in advance for any response. Regards, Tony

[veraPDF-users] Rule 6.4.3-1
by Pablo Rodriguez 18 Dec '17

18 Dec '17

Dear list, I have a ditally signed PDF/A-3 document, which verapdf-1.9.84 complains about violation of Rule 6.4.3-1. I’m checking a tool for signing PDF documents. And I don’t know whether a part of the PDF document is missing or that it included the signature data themselves. Is there any way that I have to check the Rule 6.4.3-1 for any PDF document (even if not a PDF/A document)? Many thanks for your help, Pablo -- http://www.ousia.tk
