|
||
|
||
<para>Reference documentation for particular commands, functions,
|
||
etc., is sometimes viewed in isolation from its greater "context". For
|
||
example, users view Unix man pages as, well, individual pages, not as
|
||
part of a "book" of some kind. Therefore, it is sometimes necessary to
|
||
embed "context" information in output for each <tag>refentry</tag>.</para>
|
||
|
||
|
||
|
||
<para>However, one problem is that different users mark up that
|
||
context information in different ways. Often (usually), the
|
||
context information is not actually part of the content of the
|
||
<tag>refentry</tag> itself, but instead part of the content of a
|
||
parent or ancestor element to the <tag>refentry</tag>. And
|
||
even then, DocBook provides a variety of elements that users might
|
||
potentially use to mark up the same kind of information. One user
|
||
might use the <tag>productnumber</tag> element to mark up version
|
||
information about a particular product, while another might use
|
||
the <tag>releaseinfo</tag> element.</para>
|
||
|
||
|
||
|
||
<para>Taking all that in mind, the
|
||
<function>get.refentry.metadata</function> template tries to gather
|
||
metadata from a <tag>refentry</tag> element and its ancestor
|
||
elements in an intelligent and user-configurable way. The basic
|
||
mechanism used in the XPath expressions throughout this stylesheet
|
||
is to select the relevant metadata from the *info element that is
|
||
closest to the actual <tag>refentry</tag> – either on the
|
||
<tag>refentry</tag> itself, or on its nearest ancestor.</para>
|
||
|
||
|
||
<note>
|
||
|
||
<para>The <function>get.refentry.metadata</function>
|
||
template is actually just sort of a "driver" template; it
|
||
calls other templates that do the actual data collection,
|
||
then returns the data as a set.</para>

<para>The <literal>solbook(5)</literal> man page describes
|
||
something very much like what <literal>man(7)</literal> calls
|
||
"source", except that <literal>solbook(5)</literal> names it
|
||
"software" and describes it like this:
|
||
<blockquote>
|
||
|
||
<para>This is the name of the software product that the topic
|
||
discussed on the reference page belongs to. For example UNIX
|
||
commands are part of the <literal>SunOS x.x</literal>
|
||
release.</para>
|
||
|
||
</blockquote>
|
||
</para>
|
||
|
||
|
||
|
||
<para>In practice, there are many pages that simply have a version
|
||
number in the "source" field. So, it looks like what we have is a
|
||
two-part field,
|
||
<replaceable>Name</replaceable> <replaceable>Version</replaceable>,
|
||
where:
|
||
|
||
<variablelist>
|
||
<varlistentry>
|
||
<term>Name</term>
|
||
<listitem>
|
||

</variablelist>
|

|

Each part is optional. If the <replaceable>Name</replaceable> is a

product name, then the <replaceable>Version</replaceable> is probably
|
||
the version of the product. Or there may be no
|
||
<replaceable>Name</replaceable>, in which case, if there is a
|
||
<replaceable>Version</replaceable>, it is probably the version of the
|
||
item itself, not the product it is part of. Or, if the
|
||
<replaceable>Name</replaceable> is an organization name, then there
|
||
probably will be no <replaceable>Version</replaceable>.

<para>The DocBook XSL stylesheets include several user-configurable

global stylesheet parameters for controlling <tag>refentry</tag>

metadata gathering. Those parameters are not read directly by the

other <tag>refentry</tag> metadata-gathering

templates. Instead, they are read only by the

<function>get.refentry.metadata.prefs</function> template,
