Subject [greenstone-users] extracted metadata in pagedimage collection
Hello.

I make as collection based on digitalised images of a newspapaer, exactly the same kind of collectgion than the pagedimage exemple of the Greenstone tutorial. I wish to add a Creator browser.
For this, I made the folowing .item file :

<PagedDocument>
<Metadata name="Title">Autonomie Individuelle</Metadata>
  <Metadata name="Series">Autonomie</Metadata>
  <Metadata name="Date">18870515</Metadata>
  <Metadata name="Number">1</Metadata>
   <PageGroup>
    <Metadata name="Title">Newspaper pages</Metadata>
<PageGroup>
    <Page pagenum="1" imgfile="images/1.gif">
     <Metadata name="Creator">Redaction (La)</Metadata></Page>
    <Page pagenum="2" imgfile="images/2.gif">
      <Metadata name="Title">A nos amis</Metadata>
<Metadata name="Creator">Redaction (La)</Metadata></Page>
</PageGroup>
<PageGroup>
<Metadata name="Title">A propos du suffrage universel</Metadata>
<Metadata name="Creator">Schaeffer (Charles)</Metadata>
    <Page pagenum="3" imgfile="images/3.gif">
      <Metadata name="Title">Page 3</Metadata>
<Metadata name="Creator">Schaeffer (Charles)</Metadata></Page>
    <Page pagenum="4" imgfile="images/4.gif">
      <Metadata name="Title">Page 4</Metadata></Page>
</PageGroup>
<PageGroup>
<Metadata name="Title">Compagnons de l'Autonomie Individuelle</Metadata>
<Metadata name="Creator">Louiche (Jean Baptiste)</Metadata>
<Page pagenum="5" imgfile="images/5.gif">
      <Metadata name="Title">Page 5</Metadata></Page>
  </PageGroup>
</PageGroup>
</PagedDocument>

In the GLI I add an AZList classifier (AZList -metadata ex.Creator) in the browsing classifiers of the Design panel and, in the format feature of the format panel, add the following : CL2Vlist "<td valign="top">[link][icon][/link]</td>
<td valign="top">[highlight]
{Or}{[dc.Title],[exp.Title],[ex.Title],Untitled}
[/highlight]</td>"

Then build the collection and... tada... nothing happens : the extracted Title and Date browsing classifiers work well, nothing for the Creator classifier.

Could someone tell me where is the mistake ? Why the ex.Creator metadata seems not to be extracted ?
