Use our data model to determine the queries for retrieving a resource

[mwigham]

Now, we have custom functions in ld_util to retrieve the necessary information about a resource. These are then not necessarily in sync with the model we use in lod-importer for creating the resource, so we may miss things.

Tasks

• Look at how we could use the model information to generate the queries for retrieving a resource, just as it is used to generate the mapping in lod-importer
• If feasible, implement this

Acceptance criteria

• Queries for retrieving a resource are derived from the model
