62     <p>Tree <tt class="docutils literal"><span class="pre">metadata.xml</span></tt> files are currently used to specify maintainer and
63     description information for packages. This GLEP proposes extensions to
64     <tt class="docutils literal"><span class="pre">metadata.xml</span></tt> to allow storage of information about upstream.</p>
65     </div>
66     <div class="section">
67     <h1><a class="toc-backref" href="#id3" id="motivation" name="motivation">Motivation</a></h1>
68     <p>The range of upstream-related data currently available to developers and
69     tool authors is currently limited to <tt class="docutils literal"><span class="pre">DESCRIPTION</span></tt> and <tt class="docutils literal"><span class="pre">HOMEPAGE</span></tt> in
70     ebuilds.</p>
71     <p>There have been several attempts at creating tools that check a
72     package's versions against Freshmeat to see whether an ebuild version
73     bump is required. Currently identifying a package's Freshmeat entry is a
74     matter of guesswork, and not something that can reliably be automated.</p>
75     <p>Similarly, various scripts exist to check a package's status against a
76     specialist external data source. One of the authors, for example, has a
77     shell script hack that tries to determine whether any <tt class="docutils literal"><span class="pre">app-vim</span></tt>
78     packages need bumping by checking the associated <tt class="docutils literal"><span class="pre">vim.org</span></tt> script
79     page. Again, tying packages to external data source entries is not
80     particulaly straight forward.</p>
81     <p>Making additional upstream-related data easily available will have other
82     benefits:</p>
83     <ul class="simple">
84     <li>It will allow systems such as the Packages website to provide more
85     useful information to end users.</li>
86     <li>It will reduce the time spent by developers trying to find how to
87     contact upstream.</li>
88     </ul>
89     </div>
90     <div class="section">
91     <h1><a class="toc-backref" href="#id4" id="specification" name="specification">Specification</a></h1>
92     <p><tt class="docutils literal"><span class="pre">metadata.dtd</span></tt> should allow the use of a upstream tag in
93     <tt class="docutils literal"><span class="pre">metadata.xml</span></tt>. Inside the upstream tag, developers should be able to
94     add upstream related information.</p>
95 ciaranm 1.1 <p>This GLEP defines the following four tags for <tt class="docutils literal"><span class="pre">upstream</span></tt>:
96 ciaranm 1.2 <tt class="docutils literal"><span class="pre">maintainer</span></tt>, <tt class="docutils literal"><span class="pre">changelog</span></tt>, <tt class="docutils literal"><span class="pre">bugs-to</span></tt> and <tt class="docutils literal"><span class="pre">remote-id</span></tt>, none of
97     which are mandatory. Future GLEPs may extend this -- tools processing
98     metadata.xml should ignore unrecognized elements.</p>
99     <p><tt class="docutils literal"><span class="pre">maintainer</span></tt> can contain the tags <tt class="docutils literal"><span class="pre">name</span></tt> and <tt class="docutils literal"><span class="pre">email</span></tt>, indicating
100     the person or organization responsible for upstream maintainership of
101     the package.</p>
102 ciaranm 1.1 <p><tt class="docutils literal"><span class="pre">name</span></tt> should contain a block of text with upstream's name.</p>
103     <p><tt class="docutils literal"><span class="pre">email</span></tt> should contain an e-mail address in the format <a class="reference" href="mailto:foo&#64;bar.bar">foo&#64;bar.bar</a>.</p>
104 ciaranm 1.2 <p><tt class="docutils literal"><span class="pre">changelog</span></tt> should contain a URL prefixed with <tt class="docutils literal"><span class="pre">http://</span></tt> or
105     <tt class="docutils literal"><span class="pre">https://</span></tt> where the location of the upstream changelog can be found.</p>
106     <p><tt class="docutils literal"><span class="pre">bugs-to</span></tt> should contain a place where bugs can be filed, a URL
107     prefixed with <tt class="docutils literal"><span class="pre">http://</span></tt> or <tt class="docutils literal"><span class="pre">https://</span></tt> or an e-mail address prefixed
108     with <tt class="docutils literal"><span class="pre">mailto:</span></tt>.</p>
109     <p><tt class="docutils literal"><span class="pre">remote-id</span></tt> should specify a type of package identification tracker
110     and the identification that corresponds to the package in question.
111     <tt class="docutils literal"><span class="pre">remote-id</span></tt> should make it easier to index information such as its
112     Freshmeat ID or its CPAN name.</p>
113     <p>The <tt class="docutils literal"><span class="pre">remote-id</span></tt> element has a <tt class="docutils literal"><span class="pre">type</span></tt> attribute, which is a string
114     identifying the type of upstream source. Examples are <tt class="docutils literal"><span class="pre">freshmeat</span></tt>, in
115     which case the element content should be the Freshmeat ID or <tt class="docutils literal"><span class="pre">vim</span></tt>, in
116     which case the element content should be the <tt class="docutils literal"><span class="pre">vim.org</span></tt> script
117     identifier. This GLEP does not specify a complete list of legal values
118     for <tt class="docutils literal"><span class="pre">type</span></tt> -- developers should email the <tt class="docutils literal"><span class="pre">gentoo-dev</span></tt> mailing list
119     before using a new <tt class="docutils literal"><span class="pre">type</span></tt> value.</p>
120     <p>For example, a <tt class="docutils literal"><span class="pre">metadata.xml</span></tt> upstream snippet may look like:</p>
121 ciaranm 1.1 <pre class="literal-block">
122     &lt;upstream&gt;
123 ciaranm 1.2 &lt;maintainer&gt;
124     &lt;name&gt;Foo Bar&lt;/name&gt;
125     &lt;email&gt;foo&#64;bar.bar&lt;/email&gt;
126     &lt;/maintainer&gt;
127     &lt;changelog&gt;http://foo.bar/changelog.txt&lt;/changelog&gt;
128     &lt;bugs-to&gt;https://bugs.foo.bar&lt;/bugs-to&gt;
129     &lt;remote-id type=&quot;freshmeat&quot;&gt;12345&lt;/remote-id&gt;
130     &lt;remote-id type=&quot;sourceforge&quot;&gt;foobar&lt;/remote-id&gt;
131 ciaranm 1.1 &lt;/upstream&gt;
132     </pre>
133     </div>
134 ciaranm 1.2 <div class="section">
135     <h1><a class="toc-backref" href="#id5" id="backwards-compatibility" name="backwards-compatibility">Backwards Compatibility</a></h1>
136     <p>No changes are necessary to existing <tt class="docutils literal"><span class="pre">metadata.xml</span></tt> files. Information
137     in the new tags is not be mandatory. Any sane tool that currently
138     handles <tt class="docutils literal"><span class="pre">metadata.xml</span></tt> files will simply ignore unrecognised elements.</p>
