Tim Allison commented on TIKA-1252:
-----------------------------------
This grabs both authors:
{noformat}
org.apache.jempbox.xmp.XMPMetadata xmp =
document.getDocumentCatalog().getMetadata().exportXMPMetadata();
XMPSchemaDublinCore pdfdc = xmp.getDublinCoreSchema();
List<String> creators = pdfdc.getBagList("dc:creator");
if (creators != null){
for (String c : creators){
addMetadata(metadata, TikaCoreProperties.CREATOR, c);
}
}
{noformat}

The current Tika code relies on PDFBox's PDDocumentInformation's getAuthor(),
which returns a single value.
{noformat}
PDDocumentInformation info = document.getDocumentInformation();
...
addMetadata(metadata, TikaCoreProperties.CREATOR, info.getAuthor());
{noformat}
[~alexandre.madur...@gmail.com], would you be able to attach another pdf where
you've inserted only one author? (Not bagged) I'd like to add both pdf files
to a unit test for this issue's fix.
My proposal is to try to get the creator bagList, and if that returns null,
fall back to our existing code to get the author. Sound good?
