[jira] [Commented] (PDFBOX-4196)
getUnqualifiedSequenceDateValueList returns date with undesired default
values
[ https://issues.apache.org/jira/browse/PDFBOX-4196?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16457719#comment-16457719 ]
Tilman Hausherr commented on PDFBOX-4196:
-----------------------------------------
Isn't there some method to access this data as text instead of as a date? What code are you using? Can you attach a PDF? Is my understanding that this is about reading this data? (not writing it)

> Key: PDFBOX-4196
> URL: https://issues.apache.org/jira/browse/PDFBOX-4196
> Project: PDFBox
> Issue Type: Wish
> Components: XmpBox
> Affects Versions: 2.0.8
> Reporter: Johannes Manner
> Priority: Major
>
> We try to integrate xmp metadata in pdf files (bibliograhpy metadata written in Latex) and read this metadata later on.
> The problem in this case is, that sometimes only the year attribute is specified, but the xmp metadata parsing within xmpbox creates calendar values with defaults, especially the month attribute is critical for us.
> Maybe an example is more informative:
> <dc:date>
> <rdf:Seq>
> <rdf:li>2017-06</rdf:li>
> </rdf:Seq>
> </dc:date>
> In this case, we are only interested in the year and month value. The day value should be null or filled with a non-valid value like -1 or similar.
>
> More problematic is the following case:
> <dc:date>
> <rdf:Seq>
> <rdf:li>2017</rdf:li>
> </rdf:Seq>
> </dc:date>
> Per default PDFBox fills the month with 1 -> January and my import recognices this 1 as January, but the value is not present.
> Our wish is, to have a functionality, where we can handle only information that are present and not struggeling with default values.
