[TYPO3-core] Universally/Globally Unique IDentifier in core in 6.0?

[Thomas Maroschik]

Hi,

the next thing I wanted to implement in EXT:identity is relation 
support. We will keep the sequencial id's but just as technical 
identifier. You can't change that, as every extension and nearly every 
core module expects the uid to be a integer. If it's not the module 
thinks it's a new record.

My plan was to add new relation fields along to the current ones in m:n 
and m:m relations and to inject the uuids transparently. Your 
import/export tool has to skip the regular relation fields during the 
export and to rebuild the sequencial relations after the data was 
imported. The t3d import export tool works already kind like this.

Feel free to help in this process :)

Regards

Tom
