Overview

Note:

Due to the shift from ActiveFedora to Valkyrie, we are at a crossroads where we might have

There are four conceptual high-level models for the metadata modeling:

  • AdminSet

    Where things are “physically” stored.

  • Collection

    What things “logically” belong to.

  • Work

    What the thing is about; these are often sub-divided into different work types

    (e.g. an Article, a Monograph, etc.)

  • FileSet

    Artifacts that further describe the thing.

The purpose of this module is to provide an overview and map of the modeling concepts. This is envisioned as a module to interrogate to see how Hyrax conceptually organizes your models.

For each of the above high-level models the ModelRegistry implements two methods:

  • <model_type>_classes

    These are the Ruby constants that represent the conceptual models.

  • <model_type>_rdf_representations

    These are the stored strings that help us describe what #

  • the data models. Very useful in our Solr queries when we want to filter/query on the

  • “has_model_ssim” attribute.

Consider that an AdminSet and a AdministrativeSet conceptually model the same thing; the latter implements via Valkyrie and the former via ActiveFedora.

multiple models for the versions: an ActiveFedora AdminSet and a Valkyrie AdminSet.
