Thanks. I am looking for how to do this in Isis because of the other advantages of Isis. James Agada Chief Technology Officer

A simple version is here: http://collinta.com.au/xsltforms/designer_simple.xml, it works in Firefox, not sure about other browsers.

Each permit will require an arbitrary set of information to be collected. It is not realistic for us to define all the permit types a priori as they are dynamic. This means that we have to provide a way for the users to define the properties of a permit. These properties then need to be captured during the permit application and issuance process. This is the background of the use case.

If the domain problem can be modeled like the examples you referenced, and you are looking for a dynamically generated interfaces, then Isis should be a good fit. I think I misunderstood that you wouldn't know the structure of the domain. If your domain model is best described as a nesting of hash maps (like an unknown json structure), maybe a wicket ui component could be used in Isis to provide an editing experience. I'm not sure how hierarchical data is handled so someone better qualified should speak to that.

Typically in domain driven design you know what the objects look like, so Apache Isis leverages the description of the object to create the interface. In the case of an object with an unknown structure, I'm not sure Isis would be a good fit. (Please someone let me know if I'm missing something) Are you familiar with ElasticSearch [1] or Apache Solr [2]? These applications provide full rest and persistence capabilities for objects where the structure is not known a priori. If you need a UI generated for the objects, you might look at Thymeleaf [3]. Or maybe just using a lightweight JS model binding like Knockout [4] or Angular [5] depending on your use case. All the technologies mentioned are open source.

Reading http://www.datanucleus.org/products/accessplatform_3_2/jpa/enhancer.html#runtime I understand that only with JPA you can use runtime enhancement. But if you're going to generate the classes at runtime then you can make them JDO-ready by implementing PersistanceCapable *interface* yourself. As a backend you can use MongoDB.
