Edit markup.php in administration/generatesites of the development site so that for files of type 23 (website text), the DC.Identifier would include indexen or indexfr rather than the numerical record id.
Replaced this:

$metaDataEn = setMetadata ($row['recordId'], 'en', $sitePath."/".$dirpath."/".$row['recordId']."en.html", $row['language']);
$metaDataFr = setMetadata ($row['recordId'], 'fr', $sitePath."/".$dirpath."/".$row['recordId']."fr.html", $row['language']);

with this:

//SA 091002 modified so that documents of type 23 (website texts) would return indexen or indexfr rather than record id in the DC.identifier
if ($row['documentTypeId'] == 23) {
$metaDataEn = setMetadata ($row['recordId'], 'en', $sitePath."/".$dirpath."/"."index"."en.html", $row['language']);
$metaDataFr = setMetadata ($row['recordId'], 'fr', $sitePath."/".$dirpath."/"."index"."fr.html", $row['language']);
} else {
$metaDataEn = setMetadata ($row['recordId'], 'en', $sitePath."/".$dirpath."/".$row['recordId']."en.html", $row['language']);
$metaDataFr = setMetadata ($row['recordId'], 'fr', $sitePath."/".$dirpath."/".$row['recordId']."fr.html", $row['language']);
}
