Update Alfresco Aspect Properties Via DotCMIS

[phil_barr]

Hi all,

I have successfully managed to retrieve attributes belonging to an aspect (such as cm:description and cm:title) using the Extensions available through the DotCmis API. Is there any way to update these properties using DotCmis also?

I have tried adding the aspect properties to the properties passed in the document.UpdateProperties() method, which throws a "property does not exist" error.
I have tried manipulating the values of the CmisExtensionElements, but these were just ignored during the call to UpdateProperties() and the values stayed the same.

Below is my code for retrieving the properties from a document:

            IList<ICmisExtensionElement> cmisExtensionElements = cmisObject.GetExtensions(ExtensionLevel.Properties);
            foreach (ICmisExtensionElement element in cmisExtensionElements)
            {
                foreach (var v in element.Children)
                {
                    if (v.Name == "alf:properties")
                    {
                        if (v.Children != null)
                        {
                            foreach (var a in v.Children)
                            {
                                string propId = a.Attributes["propertyDefinitionId"];
                                string displayName = a.Attributes["displayName"];

                                if (a.Children == null || a.Children.Count == 1)
                                {
                                    string value = a.Children == null ? null : a.Children[0].Value;
                                    DoSomethingWithValue(value);
                                }
                            }
                        }
                    }
                }
            }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Kind Regards,
Phil.

Hi Phil,

I am currently integrating an Alfresco 4.x installation with a C# .NET WCF client. I noticed your post and was wondering if you had made any progress with your issue, and if so, could you report your findings back to the community?

Cheers,
Tim

Hi!!

I need to know how to do all this in asp.net and c#.

I hope that you can help me!

Thank you very much

The Alf Extensions is obsolete.   It is not needed since CMIS 1.1 supports secondary types.
