This library provides basic marshaling and unmarshaling support for the RIS format.

RIS is used to encode metadata about references. The normative reference for the format can be found here:


Method 1: Install using Packagist.

  1. Follow the instructions at
  2. In your new project, create a composer.json file which requires LibRIS:
  "require": {
    "technosophos/LibRIS": ">=1.0.0"

When you next run php composer.phar install it will automatically fetch and install LibRIS.

Note that as of LibRIS 2.0.0, the Composer autoloader can load LibRIS:

require 'vendor/.composer/autoload.php';

use \LibRIS\RISReader;

$reader = new RISReader();


Method 2: Install LibRIS using Pear

Use your pear client to install LibRIS:

pear channel-discover
pear install querypath/LibRIS

For more, see

Use it in your scripts like this:

require 'LibRIS.php';

If you have already installed LibRIS using Pear, you can upgrade your library to the latest stable release by doing pear upgrade LibRIS.

Method 3: Download LibRIS

  1. Get LibRIS from the downloads page
  2. Uncompress the files (tar -zxvf LibRIS-1.0.0.tgz)
  3. Put the files where you want them to go.

Use it in your scripts like this:

require 'path/to/LibRIS.php';

Using LibRIS

General usage for this class is simple:

  • The LibRIS class is used to parse RIS.
  • The RISWriter class is used for writing RIS data into a string.

Here's an example (from test/simple_test.php):

require_once 'LibRIS/RISReader.php';
require_once 'LibRIS/RISWriter.php';

$ris = new \LibRIS\RISReader();


$records = $ris->getRecords();

$rw = new \LibRIS\RISWriter();
print $rw->writeRecords($records);

Here's a line-by-line explanation of the code above:

1. Include the libraries.
2. You don't need this if you use an autoloader.
4. Create a new LibRIS reader
5. Parse a file
7. Pretty-print the parsed records
9. Create a new writer
10. Turn our parsed record back into a valid RIS record.

The format of the records is documented in doc/RecordFormat.mdown.

Why is there a README file and a README.mdown file?

  • README is a required file for the Pear packaging system.
  • README.mdown is the GitHub-friendly README file for this project.
