Add Versionable aspect by default

msmith — Mon, 16 Jun 2008 16:13:01 GMT

Hello,I've been enabling "auto-versioning" for content by creating a content rule at "Company Home" that adds the aspect for new content.I've read in the Wiki that I can change the content model to achieve this, but that it is not offically supported:http://wiki.alfresco.com/wiki/Data_Dictionary_Gui

I am not quite sure why the wiki says it's not supported, having versionable as mandatory aspect is a better way than content rules. So I'd recommend doing that.

I believe what's not recommended is changing the content models shipped with the product (ie. the models in /alfresco/model/contentModel.xml). This means you shouldn't change any of the out-of-the-box "cm:" types, even if it's as innocuous a change as adding the versionable aspect as a mandatory aspect. The reason for this is that Alfresco reserves the right to modify the out-of-the-box models at any time, so if you modify them chances are your modifications will be lost during an upgrade.

That said you can accomplish the same thing by adding your own custom type (which inherits cm:content), making the versionable aspect mandatory for that type and then (if it's a requirement) making that type the default type for all newly created content.

Cheers,

I asked Alfresco support and got this response:
"I think you would be safest by using the rules but you are free to use that method but it is not officially supported."

So, we will stick with content rules for now.

Thanks!
