Love the class and its flexibility. One thing I have noticed is that it doesn't seem to offer the ability to include properties for metadata items. Example below.

<dc:creator id="something" dir="ltr" xml:lang="en">John Doe</dc:creator>
<meta refines="#something" property="file-as">Doe, John</meta>

I have hacked in a custom method to the OPF -> Metadata class to add properties, and expanded the OPF -> Metadata -> finalize method to add the properties in if using the EPub3 spec, but this hack is just really to suit my system and not very pretty.

Do you have any suggestions on a clean way to go about doing this with the current classes available and not expanding/extending them?

Many thanks

Cal

Can you use

->addCustomMetaValue($metaValue)

Example:

$metaValue = new DublinCore(DublinCore::CREATOR, "John Doe");
$metaValue->addAttr("id", "something");
$metaValue->addAttr("xml:lang", "en");
$book->addCustomMetaValue($metaValue);

$metaValue = new MetaValue("meta", "Doe, John");
$metaValue->addAttr("refines", "#something");
$metaValue->addAttr("property", "file-as");
$book->addCustomMetaValue($metaValue);


It's not pretty, and I'll have a look to see if I can improve it. Especially as currently DublinCore and MetaValue data are in the same array, though the dc: namespace is only added top the DublinCore objects.
