[Rdfapi-php-interest] Updating and Removing

[Jonathan H. <hen...@ya...>]

RAP is working well so far - 

I am coming from a RDMS paradigm.

How would I update and delete entries?

For example:

Say i want to change the value of a parameter...

I would pass in a value to 

$dbmodel->replace($s,$v,$o_old, $o_new)?

Can I change $s or $v if they are never an object of svo? 

For delete


$dbmodel->remove($statement) - seems simple enough, but there may be a
collection of statements - how would I delete based on a query?

Now for a bigger question- 

Why aren't Update and Delete part of RDQL?
