php SDO

As i noted earlier, i recently discovered php SDO. At first i found it very exciting piece of technology. With it it's possible to start a new DOM based on a schema.
Or so i thought. After some research i learned that it's a way of dealing with disconnected data graphs.

The whole graph thing i find very exciting, also being able to start a xml SDO from scratch i find exciting. But on the whole i think SDO for PHP is somewhat limited.

SDO has a good fit with the MVC pattern and the ability to use xpath for SDO, whether it's a xml or sql based type, i think is very exciting. It would be nice if it's possible to transform the internet dom structure to xhtml via xslt, but i have not discoverd an easy way of doing this.

So still searching for that, if i can find such a way, then SDO is defenitly the way to go for me.

Update:
ATM i have not found a way to either be able to switch easy between xml and sql or to retreive the DOM from SDO. This is an issue for me because this could be a natural fit between the declarative nature of xml , xslt and the imperative nature of programming languages such as php or java.

I think SDO is good for manipulating data and creating objects, but i still need to create my own dom to transform the contents of SDO into another form of XML, such as XHTML.

SDO as some serious issues, but i think it's still a nice piece of technology. A more detailed review will follow later.

Update:
Another nice tutorial from ibm about working with PHP SDO
