> Metadata stream should not be compressed
> ----------------------------------------
>
> Key: PDFBOX-3087
> URL: https://issues.apache.org/jira/browse/PDFBOX-3087
> Project: PDFBox
> Issue Type: Bug
> Components: Utilities
> Affects Versions: 1.8.10, 1.8.11, 2.0.0
> Reporter: Tilman Hausherr
> Assignee: Tilman Hausherr
> Priority: Minor
> Fix For: 1.8.11, 2.0.0
>
>
> In the 32000 PDF spec, in "14.3.2 Metadata Streams" it is almost suggested
> not to compress metadata, because
> {quote}
> PDF documents are often made available on the Web or in other environments,
> where many tools routinely examine, catalogue, and classify documents. These
> tools should be able to understand the self-contained description of the
> document even if they do not understand PDF.
> {quote}
> The implementation of PDMetadata produces an uncompressed metadata, but
> PDFMergerUtility saves compressed metadata. This breaks a required PDF/A-1b
> property. (happened at work today)
