<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>From the way you’ve phrased the question on oai-implementers
and metadata-librarians, it sounds like you’ve got some metadata elements
that you want to use in addition to those Dublin Core elements used in the oai_dc
schema. <o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>The short answer is that you can’t add other metadata elements
into the oai_dc schema. <o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>You can, however, have multiple occurrences of any element and you
can add other schemas to be exposed by OAI-PMH. This could be a qualified dc
schema of your own or someone else’s design or it could be from
another standard entirely. The important thing about OAI-PMH is to remember
that oai_dc is the mandated set you have to expose but you can expose as many others
as you wish. <o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>However, the bigger questions is:<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>Why do you want/ need to share this information?<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>There’s plenty of metadata used for local purposes that it
isn’t effective or necessary to share – apologies if this is an
obvious statement but many repositories conflate local metadata requirements
with the metadata schemas they expose for harvesting.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>Also – across most archives/repositories/digital libraries
oai_dc is the only metadata schema widely supported and looked for by
harvesters. Yes some services pay attention to what else is exposed and the
situation is improving but there isn’t really much of a common denominator
to take advantage of more detailed or different metadata – unless there’s
a particular community/ organisation/ federation/ service that you’re
working with. This situation is improving and if you can easily expose other standards
it is a good thing to do.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>I hope that begins to answer your question, without knowing a
bit more of the specific issues it’s hard to suggest elements or schema.<o:p></o:p></span></p>
