You simply apply aspect CLASSIFIABLE and with property CATEGORIES and add categories you want.
In java it would look like


CMLAddAspect tagAspect = new CMLAddAspect(Constants.ASPECT_CLASSIFIABLE, new NamedValue[] { new NamedValue(PropertyNames.PROP_CATEGORIES, true, null, new String[] { yourCategoriesArray }) }, null, "1");

Try to see if there are getters and setters. I don't know C# so this is as far as I can help you…

Thanks again, i really appreciate your help. This is what i get when creating an object of the CMLAddaspect class


                CMLAddAspect tag1 = new CMLAddAspect();
                tag1.aspect = "tag";
                tag1.property = tagproperties;
                tag1.where_id = "1";
‍‍‍‍‍‍

do you can any idea what should be the values for aspect ,property,where,where_id for tagging..

Thanks in Advance

Aspect name should be {http://www.alfresco.org/model/content/1.0}classifiable
Property is NamedValue object with name {http://www.alfresco.org/model/content/1.0}categories and your categories array as values (see above java example)
And you can use where or where_id. If you use where then you set your Predicate (new Predicate(new Reference[] { reference }, WORKSPACE_STORE, null); this is typically used when updating node and when you have a valid reference to your node) or you can use where_id (that is the same where_id of your CMLCreate and is used when you create the node for the first time so you can create and add aspect in one request)

Could you please tell me is the where_id is the guid of the document in alfresco
like 125d8132-91b9-4ca2-95aa-8e8736813256

No its not.
When you create node ref using CMLCreate your specified where_id because you do not have uuid because you are about to create a new node and that id is used to determin on which newly created node will you apply your aspect.
For example in one request I want to create 3 documents and apply aspects to them. I will create 3 CMLCreate and I will set where_id to "1", "2" and "3". After that i will apply aspects to those 3 (not yet created nodes) by creating 3 CMLAddAspect with where_id set to "1", "2" and "3" (linking them to correct CMLCreate). So that where_id is used to link yet to be created nodes with other actions in one request. Without that where_id you would have to make 2 request (in first request create node and get it's UUID and i second apply aspects).

If you want to update aspects then you cant use where_id (because it doesn't exist it is only used on first node creation), but use when instead which is reference (Predicate) of the actual existing node.

Thanks for you patience @jcustovic but i am really pulling my hair now :cry:


                CMLCreate create = new CMLCreate();
                create.parent = parentReference;
                create.id = "1";
                create.type = Constants.TYPE_CONTENT;
                create.property = properties;
                taggable[0] = tag1;
‍‍‍‍‍‍‍‍

This is my code for creating the file there is no where_id for CMLCreate but create.id = "1";
I gave the same id as the where_id for aspect, but it is resulting in SOAP exception (which do not have any further details)
But i think with your help i am almost there but i am missing something…
Thanks

Yes if your CMLCreate id is "1" then your CMLAddAspect where_id is also "1". That is correct.
Your CMLAddAspect should look something like:


CMLAddAspect tag1 = new CMLAddAspect();
tag1.aspect = "{http://www.alfresco.org/model/content/1.0}classifiable";
tag1.property = arrayOfOneNamedValueElement;
tag1.where_id = "1";
‍‍‍‍‍‍

oneNamedValueElement is NamedValue element with name {http://www.alfresco.org/model/content/1.0}categories and array of category names (so it must be multivalue). Be sure that category names are correct.

And in CML you add your CMLCreate and CMLAddAspect elements. This should work! You can post your exception here that will tell me more details about what your doing wrong.

Hi,
I am also trying to work with tags in the Java WebService API for Version 3.4
I have a question concerning the example of jcustovic:
The asprect uses CLASSIFIABLE attribute and then you add different categories.
From my point of view there is a difference between tags and categories, isn't it?

I also read, that adding tags via the WebService API is not supported, is that right?

At this time I didn't find a solution on how to add tags to a document! Maybe somebody can help me?

Thanks a lot,
Stefan

Hi,
I'm using Alfresco 4 java web services API and I'm trying to add a tag to a content node in Alfresco.
I'm trying your example:
CMLAddAspect tagAspect = new CMLAddAspect(Constants.ASPECT_CLASSIFIABLE, new NamedValue[] { new NamedValue(PropertyNames.PROP_CATEGORIES, true, null, new String[] { yourCategoriesArray }) }, null, "1");
but I can't find the string PropertyNames.PROP_CATEGORIES. where should it be?

EDIT: the last post by _jcn explain clearly how to solve the tagging issue. thanks
