Tika supports EXIFTool now through the External parser. Read on to find out how to use it.

Download and install EXIFTool

EXIFTool is a wonderful tool that reads videos, images, audio and other media files and that extracts EXIF metadata from them. If you're lucky, you can install EXIFTool with the following commands.

On Mac

brew install exiftool

On Linux (CentOS)

sudo yum install perl-Image-ExifTool

To verify that EXIFTool works correctly, run:

exiftool -ver

which should output something like: 9.72

Using EXIFTool with Tika

To use EXIFTool you'll need a custom Tika config that will override Tika's default MP4 parser (if you are dealing with MP4 files). You can do so by creating a file such as the one below:

    <parser class="org.apache.tika.parser.DefaultParser">
    <parser class="org.apache.tika.parser.mp4.MP4Parser">
    <parser class="org.apache.tika.parser.external.CompositeExternalParser">

Note that this config file initializes the DefaultParser a CompositeParser, and the CompositeExternalParser, and the MP4Parser. For the MP4Parser, it uses a new directive, mime-exclude, to exclude that parser from the video/mp4 type, and then to declare that CompositeExternalParser will support video/mp4. Since EXIFTool is an ExternalParser this configuration will make sure it gets called.

Once you have the config file made above, save it as a file, e.g., exif-tika-config.xml in the current directory. Then to call Tika, you can use Tika-App and/or Tika Server.

Using Tika-App

Use the following command on a file, e.g., spaghetti-to-sushi.mp4:

java -Dtika.config=exif-tika-config.xml -classpath tika-app/target/tika-app-1.9-SNAPSHOT.jar org.apache.tika.cli.TikaCLI -m spaghetti-to-sushi.mp4

Using Tika Server

You can also use Tika-Server. First, start it up:

java -Dtika.config=exif-tika-config.xml -classpath tika-server/target/tika-server-1.9-SNAPSHOT.jar org.apache.tika.server.TikaServerCli

Now, PUT a file to it, e.g., spaghetti-to-sushi.mp4:

curl -T $HOME/Movies/spaghetti-to-sushi.mp4 -H "Content-Disposition: attachment;filename=spaghetti-to-sushi.mp4" http://localhost:9998/rmeta
