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.
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.
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.
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...
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.
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.
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.
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.
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. |
Released October 2003. The release contains a number of new features together with

1.5
Table 1.5. Changes for release
1.5.1
| Item 1 | "--restricted" option |
|---|
Contributor | Liam Quinn |

then newer versions are required (autoconf 2.52 and later). As a result of the
upgrades more platforms are potentially supported. |
| Item 4 | "-x" option to osx and other
enhancements |
|---|
Contributor | Jessica Hekman |
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) |
