Services corresponding to DM and WCM features

satej_sirur

Hello,
I am trying to get a better understanding of how Alfresco implements Document Management and Web Content Management features at the level of the repository. After much poking around the repository sources, I have found little more than FileFolderService (which seems relevant to Document Management) and AVM (which seems relevant to Web Content Management). Are there other core services in the repository that are implemented specifically to support DM and WCM features? Or are these two "applications" built on top of existing 30-odd services (Node, Content, ML, and so on)?

You are right to think about WCM as an "application" built on the Alfresco core services. The other major applications of Alfresco are DM and Share.

In fact WCM uses both content stores together, but you are right that most of the web content managed by WCM goes into the AVM store where it benefits from features like sandboxes. While most of the DM content goes into the non AVM store. And there are services like deployment which are WCM specific.

Share uses both content stores together too.

And there are services like deployment which are WCM specific.

Thanks for your prompt reply. I would be interested in knowing about other repository services, such as deployment as you mentioned, which were added to provide DM and WCM features. What I mean by services is either public repository services (those annotated with @PublicService) or their implementations (e.g. AVMNodeService that implements NodeService which, in turn, is a public service).

Am I correct in understanding that there are no services beyond FileFolderService, and DeploymentService (and maybe the non-PublicService AVMNodeService) that implement DM and WCM features? I am trying to find out more information about repository services rather than content stores.

PS: Would this post be more appropriate in the forum for Repository Services?

You are right that the Applications are built on the 30 or so "core" services.

We're are in the middle of adding some "application layer" facades for WCM to make things a little easier to use and test, but that's very much work in progress.      There is also some WCM stuff (like permissions and locking) in the AVM Implementation that should probably be moved upwards.     The crucial difference between DM and WCM is whether content is sandboxed.   And sandboxes have their own permissions and workflow rules.

Here's a length list of the services.

Perfect! This is exactly what I wanted. Many thanks.
