| <refsect1><title>Description</title> |
| |
| <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>man(7)</literal> man page describes this as "the |
| source of the command", and provides the following examples: |
| |
| <itemizedlist> |
| <listitem> |
| |
| <para>For binaries, use something like: GNU, NET-2, SLS |
| Distribution, MCC Distribution.</para> |
| |
| </listitem> |
| <listitem> |
| |
| <para>For system calls, use the version of the kernel that you are |

| |
| </listitem> |
| <listitem> |
| |
| <para>For library calls, use the source of the function: GNU, BSD |
| 4.3, Linux DLL 4.4.1.</para> |
| |
| </listitem> |
| </itemizedlist> |
| |
| </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> |
| |
| <para>product name (e.g., BSD) or org. name (e.g., GNU)</para> |

| <varlistentry> |
| <term>Version</term> |
| <listitem> |
| |
| <para>version name</para> |
| |
| </listitem> |
| </varlistentry> |
| </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>. |
