creating a document log per document using CMIS

wemu — Fri, 12 Apr 2013 17:50:56 GMT

HelloI'm new to CMIS so please be a little patient with me We use Alfresco 4.x to store our documents and Apache Chemistry to communicate with Alfresco.We added a new document type into alfresco to store tif images along with some meta data. I now want to add some log-statements to these documents

Hello Wemu,

Did you check out the default audit trail provided by Alfresco? You can read more about it here : https://wiki.alfresco.com/wiki/Content_Auditing#Example_Audit_Trail

Hello

No I didn't check that until now. But that audit trail does not really match what I do. The document is not touched at all. The process around it which tries to get a new version of the document happens inside my application while Alfresco just stores the document and waits for the new version. The logs are meant to document the actions taken in the application.

It does no like like the audit trail is something for me in this case 😕

Hello Wemu,

I changed your model definition as below by adding the association as an aspect -


<?xml version="1.0" encoding="UTF-8"?>
<!– Definition of new Model –>
<model name="zpe:zpeModel" xmlns="http://www.alfresco.org/model/dictionary/1.0">

And using the below code to create documents and its association -


                Map<String, Object> properties = new HashMap<String, Object>();
      properties.put(PropertyIds.OBJECT_TYPE_ID, "D:zpe:zpeDocument");
      properties.put(PropertyIds.BASE_TYPE_ID, "zpe:zpeDocument");
      properties.put(PropertyIds.NAME,"doc"+System.currentTimeMillis());
      ContentStream cs = null;
      Document parentDoc = rootFolder.createDocument(properties, cs, VersioningState.NONE);
      
      Map<String, Object> childProperties = new HashMap<String, Object>();
      childProperties.put(PropertyIds.OBJECT_TYPE_ID, "D:zpe:documentLog");
      childProperties.put(PropertyIds.NAME,"logdoc"+System.currentTimeMillis());
      Document childDoc = rootFolder.createDocument(childProperties, cs, VersioningState.NONE);
            
      Map<String, Object> relationProperties = new HashMap<String, Object>();
      relationProperties.put("cmis:sourceId", parentDoc.getId());
      relationProperties.put("cmis:targetId", childDoc.getId());
      relationProperties.put("cmis:objectTypeId", "R:zpe:docLogs");
      relationProperties.put("cmis:name","logid"+System.currentTimeMillis());
      session.createRelationship(relationProperties, null, null, null);
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I used the CMIS workbench tool and found that when I go with your definition [zpe:documentLogs association is not listed under Relationship (cmis:relationship)] but when I add it as an aspect it gets listed under it.

Hope so that helps you.
