A core retrieving paths and/or data from the product table.

You will not usually mention this core in your RDs. It is mainly used internally to serve /getproduct queries.

It is instanciated from within //products.rd and relies on tables within that RD.

The input data consists of accref; you can use the string form of RAccrefs, and if you renderer wants, it can pass in ready-made RAccrefs. You can pass accrefs in through both an accref param and table rows.

The accref param is the normal way if you just want to retrieve a single image, the table case is for building tar files and such. There is one core instance in //products for each case.

The core returns a list of instances of a subclass of ProductBase above.

This core and its supporting machinery handles all the fancy product functionality (user autorisation, cutouts, ...).
