-----------------------------------
Summary: AutoDetectParser Gets Different Value for metadata
dcterms:modified from msg File with Tika 3.2.3
Key: TIKA-4798
URL: https://issues.apache.org/jira/browse/TIKA-4798
Project: Tika
Issue Type: Bug
Components: detector
Affects Versions: 3.2.3
Reporter: Xiaohong Yang
Attachments: Program_and_Sample_Files.zip
[^Program_and_Sample_Files.zip]
We use Tika to extract metadata from msg files. We found out that the value
of metadata dcterms:modified with Tika 3.2.3 is different from that with Tika
2.9.0 for some msg files.
Following is the stand alone program that reproduces the problem with the
attached sample files. The Java version is 21.
import org.apache.tika.config.TikaConfig;
import org.apache.tika.metadata.Metadata;
import org.apache.tika.parser.AutoDetectParser;
import org.apache.tika.parser.ParseContext;
import org.xml.sax.helpers.DefaultHandler;
import java.io.BufferedInputStream;
import java.io.File;
import java.io.FileInputStream;
public class TestAutoDetectParser {
public static void main(String args[]) {
try {
System.{_}out{_}.println("Start");
File inputFile = new
File("C:\\Users\\xyang\\Data\\testdirs\\TC321926\\Sample1.msg");
TikaConfig config = new
TikaConfig("C:\\Users\\xyang\\Data\\testdirs\\TC321926\\tika-config.xml");
ParseContext context = new ParseContext();
context.set(TikaConfig.class, config);
Metadata metadata = new Metadata();
try (BufferedInputStream inputStream = new BufferedInputStream(new
FileInputStream(inputFile))) {
new AutoDetectParser(config).parse(inputStream, new
DefaultHandler(), metadata, context);
}
for (String name : metadata.names()) {
System.{_}out{_}.println(name + ": " + metadata.get(name));
}
System.{_}out{_}.println("End");
}
catch(Exception ex) {
ex.printStackTrace();
}
}
}
The metadata with Tika 2.9.0 is:
dcterms:modified: 2018-08-03T19:13:22Z
And the metadata with Tika 3.2.3 is:
dcterms:modified: 2018-10-06T00:03:21Z
Wonder if it is an improvement in 3.2.3 or a bug.
Attached are 4 files:
TestAutoDetectParser.java --- the standalone program
tika-config.xml --- config file
Sample1.msg --- Sample file
Sample2.msg --- Sample file
Sample3.msg --- Sample file
