[TYPO3-semantic] Brain storming - Interfaces

[Fabien Udriot]

Hi,

This post is related to the previous one about storing nodes within a hierarchy.

I have put bellow a first draft of interfaces that I reckon being useful. Perhaps, we can also get 
inspired by other framework. Any pointer may be welcomed.


Interface for QUERYING
======================

- Array of Node $objects : findObjects (Node $subject, String $predicate)

- Array of Node $subjects : findSubjects (Node $object, String $predicate)

- Array of String $predicate : findPredicates (Node $subject, Node $object)


Interface FOR STORING
=====================

- Triple addTriple (Node $subject, Node $object, String $predicate)

- Triple removeTriple (Node $subject, Node $object, String $predicate)


Pending question
================

- Convenience Interface may be useful:
   Tripple updateTripple (Node $subject, Node $object, String $oldPredicate, String $oldPredicate)

- How can I sort an array of nodes? Use Case: sort by alphanumeric a bunch of concepts

- other useful interfaces such as addCollection(), addSequence() found here:
