Fetch properties from content fragment

I have a content fragment the jcr of which has got a child node named master within which the values are stored. Say there is a property xyz whose value is a group of tags, (this is stored in master node) now how do I fetch that property's values into my sling model. If someone could provide me with the code/explanation of the steps, it'll be really helpful.
