> This is an issue to track progress towards giving the file manager the
> ability to deal with product collections. Collections are defined as one or
> more products, and an associated metadata object. The major design trade off
> is going to be the level of granularity with regards to how the filemgr will
> provide collections, in other words, will the file manager natively support a
> collections object? Or, will the filemgr support collections through the use
> of additional meta-information in the product object?
> I'm leaning towards natively creating an core filemgr object, called
> ProductCollection, and adding an attribute to the Product class of type
> ProductCollection, that is an instance of the ProductCollection for which the
> Product belongs to. So, the Product class would have an additional field,
> like:
> {code:java}
> private ProductCollection collection;
> {code}
> and we'd have an additional class like:
> {code:java}
> public class ProductCollection{
> private String id;
> private String name;
> private List<Product> products;
> private Metadata met;
> //....
> }
> {code}
> Collection information would be transferable via XML-RPC using an external
> API that we would add to the filemgr to support dealing with Collections. The
> API would look like:
> {code:java}
> public interface Collectable{
> public ProductCollection getCollection(Product p);
> public void addProductToCollection(Product p, ProductCollection c);
> public List<Product> getProducts(ProductCollection c);
> public Metadata getCollectionMetadata(ProductCollection c);
> }
> {code}
> One open issue is whether or not a Product can belong to multiple
> ProductCollections. I think that ultimately it should be able to, but to keep
> the API clean and simple for now, we'll restrict a Product's membership to a
> single ProductCollection.
