Back to the Fedora: Part 3
This is the penultimate post in this series. The final post will describe an aggregate object ("study") that will contain relatively little content, but which serves as a grouping element for more basic elements.
The object to the left is a conventional Fedora Data Object, but I include it here as an example where we have important content to preserve and deliver, and where the content is somewhat of a "one off" and doesn't conform to a unique Content Model.
In this case we have the survey instrument that was used to collect the data in icpsr:eager-survey-data-25041.
The instrument is available in two different languages (English and Spanish), and while the original deposit was PDF-format, we have also produced a TIFF-format of each version for preservation purposes. This translates into a simple object with four Datastreams, one for each (language, format) combination.
We assert membership to the aggregate "study" object in RELS-EXT. We also assert a connection to the associated dataset using a custom relationship we minted: isInstrumentFor. It isn't clear (yet) if having a specialized relationship such as this will be any more useful than a less descriptive relationship (e.g., isRelatedTo, to make one up).
