tika-python

A Python port of the Apache Tika library that makes Tika available using the Tika REST Server.

This makes Apache Tika available as a Python library, installable via Setuptools, Pip and Easy Install.

To use this library, you need to have Java 7+ installed on your system as tika-python starts up the Tika REST server in the background.

Inspired by Aptivate Tika.

Installation (with pip)

1. pip install tika

Installation (without pip)

1. python setup.py build
2. python setup.py install

Testing it out

Parser Interface (backwards compat prior to REST)

#!/usr/bin/env python
import tika
tika.initVM()
from tika import parser
parsed = parser.from_file('/path/to/file')
print(parsed["metadata"])
print(parsed["content"])

Parser Interface (new)

#!/usr/bin/env python
import tika
from tika import parser
parsed = parser.from_file('/path/to/file')
print(parsed["metadata"])
print(parsed["content"])

# Optionally, you can pass Tika server URL along with the call
# what's useful for multi-instance execution or when Tika is dockerzed/linked
parsed = parser.from_file('/path/to/file', 'http://tika:9998/tika')
string_parsed = parser.from_buffer('Good evening, Dave', 'http://tika:9998/tika')

Detect Interface (new)

#!/usr/bin/env python
import tika
from tika import detector
print(detector.from_file('/path/to/file'))

Config Interface (new)

#!/usr/bin/env python
import tika
from tika import config
print(config.getParsers())
print(config.getMimeTypes())
print(config.getDetectors())

Language Detection Interface (new)

#!/usr/bin/env python
from tika import language
print(language.from_file('/path/to/file'))

Translate Interface (new)

#!/usr/bin/env python
from tika import translate
print(translate.from_file('/path/to/spanish', 'es', 'en'))

Using a Buffer

Note you can also use a Parser and Detector .from_buffer(string) method to dynamically parser a string buffer in Python and/or detect its MIME type. This is useful if you've already loaded the content into memory.

Using Client Only Mode

You can set Tika to use Client only mode by setting

import tika
tika.tika.TikaClientOnly = True

Then you can run any of the methods and it will fully omit the check to see if the service on localhost is running and omit printing the check messages.

New Command Line Client Tool

When you install Tika-Python you also get a new command line client tool, tika-python installed in your /path/to/python/bin directory.

The options and help for the command line tool can be seen by typing tika-python without any arguments. This will also download a copy of the tika-server jar and start it if you haven't done so already.

tika.py [-v] [-o <outputDir>] [--server <TikaServerEndpoint>] [--install <UrlToTikaServerJar>] [--port <portNumber>] <command> <option> <urlOrPathToFile>

tika.py parse all test.pdf test2.pdf                   (write output JSON metadata files for test1.pdf_meta.json and test2.pdf_meta.json)
tika.py detect type test.pdf                           (returns mime-type as text/plain)
tika.py language file french.txt                       (returns language e.g., fr as text/plain)
tika.py translate fr:en french.txt                     (translates the file french.txt from french to english)
tika.py config mime-types                              (see what mime-types the Tika Server can handle)

A simple python and command-line client for Tika using the standalone Tika server (JAR file).
All commands return results in JSON format by default (except text in text/plain).

To parse docs, use:
tika.py parse <meta | text | all> <path>

To check the configuration of the Tika server, use:
tika.py config <mime-types | detectors | parsers>

Commands:
  parse  = parse the input file and write a JSON doc file.ext_meta.json containing the extracted metadata, text, or both
  detect type = parse the stream and 'detect' the MIME/media type, return in text/plain
  language file = parse the file stream and identify the language of the text, return its 2 character code in text/plain
  translate src:dest = parse and extract text and then translate the text from source language to destination language
  config = return a JSON doc describing the configuration of the Tika server (i.e. mime-types it
             can handle, or installed detectors or parsers)

Arguments:
  urlOrPathToFile = file to be parsed, if URL it will first be retrieved and then passed to Tika

Switches:
  --verbose, -v                  = verbose mode
  --server <TikaServerEndpoint>  = use a remote Tika Server at this endpoint, otherwise use local server
  --install <UrlToTikaServerJar> = download and exec Tika Server (JAR file), starting server on default port 9998

Example usage as python client:
-- from tika import runCommand, parse1
-- jsonOutput = runCommand('parse', 'all', filename)
 or
-- jsonOutput = parse1('all', filename)
