I think for most if not all the Java based scripting languages we can just
expose the Java SDO API to the scripting language (at one point we had a
JavaScript version of the Big Bank sample account module that did this),
but
there are probably ways to use the dynamic nature of the script languages
to
come up with a simplify SDO API.

The SDO API in PHP is fairly similar to the C++ SDO but is simplified and
in particular it tries to take avantage of the features of PHP so that it is
comfortable to use for the PHP programmer. For example, a typical user of
the XML DAS might do
$xmldas->addTypes("company.xsd");
$document = $xmldas->loadFile("company.xml");
$company = $document->getRootDataObject();
$company_name = $company->name; // property access style
$company_name = $company['name']; // associative array access style
$company_name = $company[0]; // index array access style
The trick is make the experience as natural for the script developer
as possible so we have, for example, provided all the normal PHP
object access styles.
Also our user space implementation of the relational DAS is quite
different from the current java implementation.
