I'm currently using openCMIS to create a node inside Alfresco. I want to specify that the newly made content uses a specific nodeRef id. For example:

workspace://SpacesStore/6e619192-61c0-46fc-85c1-81badbb9b93e

Currently I have this CMIS code:

Map<String, Object> properties = new HashMap<String, Object>();
properties.put(PropertyIds.OBJECT_TYPE_ID, "cmis:folder");
properties.put(PropertyIds.NAME, "TestFolder");
properties.put(PropertyIds.OBJECT_ID, "workspace://SpacesStore/6e619192-61c0-46fc-85c1-81badbb9b93e");
folder.createFolder(properties);

I want it that the newly made folder Names "TestFolder" has an nodeRef that matches the OBJECT_ID specified. However Alfresco still generates a different unique nodeRef.

Is there a way to specify a nodeRef when creating content in Alfresco?

No, it is not possible to set your own node reference. It's an implementation detail that, in theory, you shouldn't care about.

However, you may have a valid reason for this (for example, importing data from an existing repository?). If for some reason you need to keep this node reference, consider storing this noderef as a separate metadata property.

You may want to submit a separate question explaining in more detail why you want to do something like this.

  • It's as you said. I want to import data from an already existing repository. There are third party applications that reference to the nodeRefs. Therefore I want to retain the same nodeRefs when migrating the content – Kevin Groen Mar 31 '17 at 08:09

I will preface this by saying - there isn't a public API for this for a reason! You really shouldn't be doing that in normal use...

If you want to create a node with a well-known node reference, you should create an ACP file and bootstrap it in. This is how Alfresco creates some well known nodes, such as rendering_actions_space at /app:company_home/app:dictionary/app:rendering_actions with noderef workspace://SpacesStore/rendering_actions_space . See here in the Alfresco source code on github for how to do that

If you really really need to create a node with a specific noderef, which you normally don't, you can pass the ContentModel.PROP_NODE_UUID property to the NodeService, as part of the properties when creating a node, and if possible that'll be used to set the ID part of the new noderef. Generally though, you shouldn't be doing this!

Actually, you could write Java class and provide Properties for node when creating it. If you will provide node-uuid, node will be created with it, and NodeRef consists basically of storeref and node-uuid.
