Aggregation: simple proposal

Since Andy started a mail on aggregation just now, I'll put forward
a default suggestion that can work with the notion of strict containership
of collections we have settled with at TPAC2012.

1. Create a aggregation container

POST your collection to the container

<> primaryTopic <#wk> .

<#cnt> a WeakContainer;
    :contains <>,
           <localRes> .

This creates a resource named say <resourceC> which defined
<resourceC#cnt> .
the :contains relation is left open for later. 

2. Delete your container

send an HTTP delete message

  DELETE resourceC HTTP/1.1

or change the container as below by removing the <#cnt> from <resourceC>

3. Change your container

Say you want to remove <> from <resourceC#cnt>
then just 

PUT resourceC HTTP/1.1

<> primaryTopic <#wk> .

<#cnt> a WeakContainer;
    :contains <localRes> .

4 Optimisations

Define a Patch method to make it efficient to make changes.

Using SPARQL - just as an example - one could 

DELETE { <#cnt> :contains <> }

Since one does not use lists, this is really easy.
