General DOAP Guidelines

rdf:resource should be used when listing URLs.
```
i.e. <doap:homepage rdf:resource="https://foo.apache.org/" />
```
is the correct form to use.
the doap:Project element may be embedded in other styles of feed, e.g. within an Atom feed. When included in such a way it should still follow all guidelines, even if this means duplicating information.
Dates should be formatted as 'YYYY-MM-DD'. Numbers should be padded with '0' to match the formatting.
```
e.g. Jan 1st 2001 should be written as '2001-01-01'
```
all URLs should be fully qualified, including the protocol.
```
i.e. https://foo.bar.com/file.html
```

projects should include the 'Apache' prefix when listing their project name.
```
i.e. 'Apache HTTPD' instead of 'HTTPD'.
```

programming languages should be given as capitals unless their well known name is mixed case.
```
e.g. Java, SVG, Tcl, Perl, etc
```
A full list of programming langauges we accept is available here
all releases should have a "product" name (added using a doap:name element) included in the doap:Version element.
```
  i.e.
    "<doap:Version>
      <doap:name>Blah</doap:name>..."
```
The categories that a project should be recorded as being within are recorded as rdf:resource using the following format
```
 https://projects.apache.org/category/<category>
  e.g. <doap:category rdf:resource="https://projects.apache.org/category/mail" />
```
A list of the categories is available here
the shortdesc element is used for providing a brief description on index pages and should be included.

PMC descriptor files must always have the extension '.rdf', and must be listed in the file
https://svn.apache.org/repos/asf/comdev/projects.apache.org/trunk/data/committees.xml
PMCs can be referenced as an rdf:resource that points at https://<pmc>.apache.org/. e.g.
<asfext:pmc rdf:resource="https://httpd.apache.org/" />.
In this case, the PMC descriptor file must be called <pmc>.rdf and must be stored in the directory:
https://svn.apache.org/repos/asf/comdev/projects.apache.org/trunk/data/committees/
PMCs descriptors can also be stored anywhere else (e.g. on the TLP website or in SVN), in which case they must be referenced using the full URL, for example
<asfext:pmc rdf:resource="https://tlp.apache.org/pmc/tlp.rdf" />
