# Chapter 1. OpenSP 1.5.2 Release Notes

The OpenJade project provides a suite of tools and libraries for validating, processing and applying DSSSL (Document Style Semantics and Specification Language) style sheets to SGML and XML documents.

OpenJade is a project undertaken by the community to maintain and extend James Clark's Jade, as well as the related SP suite of SGML/XML processing tools. OpenJade and OpenSP are distributed under the same license as Jade.

OpenSP is written in C++ and provides a class library, libosp, which can be used as a basis for either open source or commerical projects. The library can be built as either a dynamic or static library.

## Applications of OpenSP

The OpenSP library has been used in a number of projects. The World Wide Web consortium on-line HTML and XHTML validator is based on the OpenSP library. In addition to the OpenSP library a set of command line tools are provided to support the validation and transformation of SGML files. In particular onsgmls can validate both XML and SGML documents held on a local file system or accessed remotely via a web server using the HTTP protocol with standard URI notation; osx will convert SGML to XML to allow a library of SGML documents to be processed with XML tools.

## Obtaining OpenSP

OpenSP is a project hosted at sourceforge.net and is available from the OpenJade web site at http://openjade.sourceforge.net or directly from the OpenJade project page at http://sourceforge.net/projects/openjade

OpenSP is provided in source code form. However, see the section called “Binary Distributions” for information on how to obtain pre-compiled binary packages.

## Supported Platforms

OpenSP is intended to be as portable as possible. It should be possible to compile and build on most contemporary UNIX type platforms. In addition OpenSP should also build on Microsoft's Win32 based operating systems.

OpenSP is known to compile with both the GNU gcc c++ compiler and Microsoft Visual C++. Other compilers have not been extensively tested.

OpenSP 1.5.2 should build with the GNU gcc c++ compiler from version 2.95 up to version 4.0.

OpenSP has been built on a number of architectures including Intel i386 and ia64, Alpha AXP, Sparc, PPC and S/390.

The following table details known successful builds

## Building OpenSP from Source

OpenSP requires 20Mb to 50Mb of disk space to build. An installation will require around 10Mb to 20Mb depending on architecture.

On UNIX platforms, OpenSP makes use of the GNU software configuration tools (autoconf, libtool, automake etc). The GNU C++ compiler and make utility should also be used. The steps required to build the OpenSP tools (onsgmls, osgmlnorm, ospam, ospcat, ospent, osx) and libraries are as follows:

    gzip -d OpenSP-1.5.2.tar.gz | tar xvf -
    cd OpenSP-1.5.2
    ./configure [options...]
    make

You may need to switch to the super user root to complete the installation

    make install

The configure script supports many options. These can be displayed using the command

    ./configure --help

In addition to the standard options, the following table describes options specific to OpenSP.

Table 1.2. OpenSP specific configure options

Option | Default | Explanation
--- | --- | ---
`--enable-http` | No http support | Include support for http. This allows the OpenSP tools to be used to validate or process SGML or XML documents directly from the World Wide Web. Example:
    onsgmls -s http://www.example.com
`--enable-default-catalog=`pathlist`` | Not enabled | Provide one or more default catalog files or sysids, e.g. /usr/local/lib/sgml/catalog
`--enable-default-search-path=`pathlist`` | Not enabled | Provide a default value for `SGML_SEARCH_PATH`
`--enable-xml-messages` | Not enabled | Include support for XML Formatted Messages
`--disable-doc-build` | Enabled | Do not build docs (man pages and release notes)
`--disable-dtddecl` | Enabled | Do not include support for DTDDECL

Please refer to the system documentation for details on building on the Win32 platform.

## Binary Distributions

In addition to binary packages availble from the project, OpenSP has been a part of many software distributions, including the major Linux distributions as well as FreeBSD. Expect pre-compiled and packaged versions of the latest version of OpenSP to be available from your distributor in due course.

## Installation

In addition to the OpenSP executables and libraries you will also need various DTDs and declaration files. Some DTDs and associated files (entity definitions) are available in the `pubtext` directory of the distribution. However, more authoritative sources should be referenced to ensure that up-to-date versions are used. If you wish to process XML files, then suitable SGML declarations for valid XML documents should be used. Again, a sample set of declarations (`xml.dcl`) is provided in the `pubtext`, but more complete or recent versions may be available from other sources.

OpenSP supports the standard SGML catalog facility; it is recommended that you set up and use such a catalog system.

## Support

If, after reading the documentation, you still have a problem, then you may require some additional help. The OpenJade project is a volunteer effort and as such does not provide any formal support. Instead, you should look to the community for support. Once part of the community, you, in turn, will be able to play your part in helping those that come after you. Here are some pointers to obtaining help:

- If you obtained your OpenSP distribution in binary form from your operating system distributor and you have a build related problem - such as onsgmls crashing, then your first port of call should be your distributor.

- If you have a problem with the usage of the OpenSP tools, then you should try the openjade-users mailing list, see http://sf.net/projects/openjade/ for details.

- If you have a patch or bug fix for OpenJade, or are trying to use the OpenSP API then the openjade-devel mailing list is the appropriate forum.

Please choose only one mailing list to post to, as cross-posting is generally frowned upon. The various mailing lists are archived and searchable. It is always worth searching for your problem first, as it is often the case that someone has had the same problem before.

## Version 1.5.2

Released December 2005. The release contains a number of enhancements together with support for version 4.0 of the GNU C++ compiler.

The following table details the major improvements in OpenSP 1.5.2

Table 1.3. Changes for release 1.5.2

Item 1 | Added doc building and config option
--- | ---
Contributors | Terje Bless, Neil Roeth
Category | Enhancement
Description | Enable creation of release notes and man pages as part of the standard build process. Added option --disable-doc-build; this step requires several additional software packages, so a user who chooses not to install those tools or otherwise has problems building the docs can skip this step.

Item 2 | Updated local gettext
--- | ---
Contributor | Terje Bless
Category | Enhancement
Description | A local gettext is provided for those platforms that have an old or broken gettext. This has been updated to version 0.14.5.

Item 3 | Added config option to turn off DTDDECL support
--- | ---
Contributor | Neil Roeth
Category | Enhancement
Description | Added option --disable-dtddecl to disable DTDDECL support. The combination of DTDDECL support and enabling a default catalog and default SGML search path can cause poor performance. Using this option allows you to use a default catalog and search path and still get good performance if DTDDECL support is not needed.

Item 4 | Updated/added translations
--- | ---
Contributor | Karl Eichwalder
Category | Enhancement
Description | Updated German and French translations, added Turkish translation.

The following table details the major improvements in OpenSP 1.5

Table 1.5. Changes for release 1.5.1

Item 1 | "--restricted" option

Item 6 | Enhanced Message Handling
--- | ---
Contributor | Epremis Corporation (Peter Newcomb)

Item 7 | Error Messages formatted as XML
--- | ---
Contributor | Nick Kew
Category | Software Enhancement

Contributor | Epremis Corporation (Peter Newcomb)
Category | Software Enhancement
Description | Added support for the PI-based architecture using declaration syntax defined by Amendment 1 to ISO/IEC 10744:1997 (HyTime). This makes it possible to specify architectural support attributes when using architectures with XML, and is generally simpler than the original syntax. See http://www.ornl.gov/sgml/wg8/document/1985.htm for details.

Item 9 | Support name based virtual hosts when parsing a URI
--- | ---
Contributor | Liam Quinn (and others)
