Creating properties and namespaces with WD4J

Question

Hello,
In several tutorials (like one of building a bulletin board, .. ) the properties are always customizied by hand. The thing is that I need to create them via program. In this way I don't know if it is possible to create the properties and the namespace (like I can do it in the metadata administration).
I just want the following:
- I have a entry for an article (name, title, category, description, ... )
- I want to add some documents to the entry
- For this entry I have several (own) properties
Later on (and I think that I know how to do this) I want:
- to display an overview of the articles with some filter capabilities
- showing a detail page
- Develop some renderer for being used be the enterprise search
The thing I don't get is how to create the properties with WD4J?
Could someone help and bring some light into my darkness?
Thank you,
  Vanessa

Hi Vanessa,
Why do you want to create the property through WD4J?
You can have this one time  task done through metadata administration.
Later in your application you can set/get the values for these properties.
IResource res = ResourceFactory.getInstance().getResource(path,context);
//Create Property Names...
IPropertyName propNameName = new PropertyName("http://sap.com/xmlns/cm","name");
IPropertyName propNameTitle = new PropertyName("http://sap.com/xmlns/cm","title");
IPropertyName propNameCategory = new PropertyName("http://sap.com/xmlns/cm","category");
IPropertyName propNameDescription = new PropertyName("http://sap.com/xmlns/cm","description");
//Create properties
IProperty propertyName = new Property(propNameName , "your Name Value");
IProperty propertyTitle = new Property(propNameTitle , "your Title Value");
IProperty propertyCategory = new Property(propNameCategory , "your Category Value");
IProperty propertyDescription = new Property(propNameDescription , "your Desc Value");
//Create a map to put all properties
IMutablePropertyMap newPropertiesMap = new MutablePropertyMap();
newPropertiesMap.put(propertyName );
newPropertiesMap.put(propertyTitle );
newPropertiesMap.put(propertyCategory );
newPropertiesMap.put(propertyDescription );
//Set the properties to the resource at one go.
res.setProperties(newPropertiesMap );
Also use [Java Docs|https://help.sap.com/javadocs/NW04s/current/km/com/sapportals/wcm/repository/IResource.html] this along with your development...
