HelloI access alfresco 5.2 repository through opencmis api.I need to be able to store key value pairs (propeties?) that are not predefined and therefore i cant add them as type properties to content model.

Secondary types are not a mechanism for solving this problem. I sent a lengthy reply to this topic on the Apache Chemistry list, so I'll not repeat it here.

A short summary of my reply was: Don't use Alfresco for this. Use a more flexible persistence store.

Thanks for your suggestions. Long term solution would be to use Solr for flexible querying. For now, i need temporary solution.

As Jeff said, Alfresco Content Services is a traditional ECM product that enforces consistency in your model. This will save you headaches in many use cases, but does require that you know your content model in advance.

What is your use case that causes you to want to use Alfresco for dynamic properties / key-value pairs? Why would you prefer Alfresco to a different storage solution such as a NoSQL repository?

Yeah, I understand. So we have negotiated the requirements and we don't need to create properties dynamically anymore. Previously, different clients were described by different metadata. but we standardised them a bit.

Thanks for your reply.

We have been investigating whether this is a capability we should deliver, and so I would appreciate learning more about your use case.

Do you like your solution better than the previous design, or do you still wish the product delivered dynamic properties?

I think it would be useful to have this feature available.

I have DMS solution that serves different customers and each of them would send us their own specific properties.
We have negotiated requirements and we have to ask every customer to send only properties with some predefined names. It is acceptable now, but would be nicer if we could not enforce every customer to translate their domain to our constraints.
