I am trying to implement a system that could store any kind of features for an object, the object can be any class of object. For each object i will save it's features using xml into the database. For each class of objects i will use a validation (DTD or XSD) constructed dynamically constructed by user, in order to validate the product before it's saved into database. A feature of the object can be any type of data : string, char, int,double, picture, video,etc.
Can you point me in some articles, examples, code snippets or best code oriented approach in order to obtain the goals i stated before?
From a previous question I've seen that this is the best approach.
Thanks,
