DocBook SGML DTD-3.1

Introduction to DocBook SGML DTD

The DocBook SGML DTD package contains document type definitions for verification of SGML data files against the DocBook rule set. These are useful for structuring books and software documentation to a standard allowing you to utilize transformations already written for that standard.

Package Information

DocBook SGML DTD Dependencies

Required

SGML Common-0.6.3 and UnZip-5.52

Installation of DocBook SGML DTD

[Note]

Note

The package source is distributed in zip format and requires unzip. You should create a directory and change to that directory before unzipping the file to ease the removal of the source files after the package has been installed.

Install DocBook SGML DTD by running the following commands: 

sed -i -e '/ISO 8879/d' \
    -e 's|DTDDECL "-//OASIS//DTD DocBook V3.1//EN"|SGMLDECL|g' \
    docbook.cat

Now, as the root user: 

install -v -d -m755 /usr/share/sgml/docbook/sgml-dtd-3.1 &&
chown -R root:root . &&
install -v docbook.cat /usr/share/sgml/docbook/sgml-dtd-3.1/catalog &&
cp -v -af *.dtd *.mod *.dcl /usr/share/sgml/docbook/sgml-dtd-3.1 &&
install-catalog --add /etc/sgml/sgml-docbook-dtd-3.1.cat \
    /usr/share/sgml/docbook/sgml-dtd-3.1/catalog &&
install-catalog --add /etc/sgml/sgml-docbook-dtd-3.1.cat \
    /etc/sgml/sgml-docbook.cat

Command Explanations

sed -i -e '/ISO 8879/d' docbook.cat: This command removes the ENT definitions from the catalog file.

sed -i -e 's|DTDDECL "-//OASIS//DTD Docbook V3.1//EN"|SGMLDECL|g' docbook.cat: This command replaces the DTDDECL catalog entry, which is not supported by Linux SGML tools, with the SGMLDECL catalog entry.
