# Distribution packages

DITA-OT is available in three three binary packages, as well as in a source package.

## Minimal package (DITA-OT1.5.4_minimal_bin.zip).

This package is primarily for use by vendors that embed the toolkit within their products. It contains all of the core processing code: CSS and XSLT, Ant build scripts, Java code (dost.jar), resource files, DTDs and Schemas. Users will need to have their own version of Ant and other libraries, and will need to set up environment variables for each library. The only external files inside the minimal package are the OASIS DTDs and Schemas, along with the following open source libraries:

- Apache Commons Codec 1.4
- Apache Catalog Resolver 1.1

## Standard package (DITA-OT1.5.4_bin.zip)

This package contains everything in the minimal package, plus documentation, existing demo code (such as legacy support for the old bookmap), sample Ant scripts, and sample DITA files. This package is appropriate for those who want the core toolkit function, demos, and samples, but already have local installed copies of Ant and other required tools. The standard package includes only the following open source libraries:

- Apache Commons Codec 1.4
- Apache Catalog Resolver 1.1

## Full Easy Install package (DITA-OT1.5.4_full_easy_install_bin.zip)

This package contains everything in the Standard package, plus common Apache tools used for builds so that you do not need to set them up separately; the only core tool that is missing is Java. This package also contains a batch file to set up a build environment using those tools. This package is appropriate for novice users, those testing the toolkit, or those who do not want to maintain local copies of other Apache tools. The following external libraries are included in version 1.5.4 of this package:

- Apache Ant 1.7.1
- Saxon 9.1
- Apache Commons Codec 1.4
- Apache Catalog Resolver 1.1
- IBM ICU for Java 3.4.4
- Apache FOP 1.0

## Source package (DITA-OT1.5.4_src.zip)

In addition to the binary versions of the toolkit, there is a source package available that contains all of the source code used in each of the three packages. The demo files, samples, and documentation are not part of the source package.The source package contains the Apache Commons Logging and Apache Catalog Resolver libraries.
