Metadata at e.g. textfiles

[Kai-Uwe Schmidt <ku...@bel-it.de>]

Hi all,

is there a way to get e.g. creator and or creation date into the metadata dictionary?

When I extract from a file I get the following:

Content-Encoding: ISO-8859-1
Content-Length: 9
Content-Type: text/plain; charset=ISO-8859-1
resourceName: TikaTestText.txt

I am missing creator and creation time.

Any hints?

Mit freundlichen Grüßen

AW: Metadata at e.g. textfiles

I was referring to metadata without having a technical view on this.  I understand from a tika-developer point of view it's not possible to offer metadata that might be stored in proprietary/system dependent stores. Information like last write time or creator or even creation time are mostly stored by the filesystem, not the document.

Java 7's BasicFileAttributes would be a very nice improvement for tika!

Ditto what Nick said on "internal" metadata.  Are you referring to "external" metadata that we could get in Java 7 via BasicFileAttributes on OS's that support those?

Plain text files don't include creator or creation dates in them. If you try with a format that does, eg PDF or Word, you should see them reported
