This page contains information on the data of De Danske Aviser, and its representation and data model in MiniDOMS.

== Data model objects and inter-object relations ==

Below, the fourth draft of the data model.

{{attachment:DDADataModelV4.png}}

The data model loosely follows the structure of the original publication.
As such it is divided into a number of volumes (based on period).

Each Volume is divided as
 * Region
 * Town
 * Paper
 * Page
 * .png

These divisions loosely follow those of the original publication.

 * Each '''Page''' in the original publication has been digitalized as a .png file, found in the bit storage, and associated with a page object.
 These must be connected to each the former and the previous page.

 * Each '''Paper''' has an entry covering one or more pages and refers to the first page of the entry.

 * The '''Region''' object references a few pages containing information on the specific area during the relevant period. The end-users should see the word "Gruppering" rather than "Region", as this level of information in the structure of the physical books is used for geographical regions as well as other ways of grouping.
 * Similarly each '''Volume''' contains a few pages dealing with subject relevant to newspaper publication on a national basis.


== On-object metadata ==

== Regarding bundling of objects ==
A bundle contains a number of objects, and one of the objects has special status - namely the object that is ''central'' to the bundle.

Special note: We also need bundles for page objects. Such a bundle should comprise volume, region, town, and paper objects, since they all reference pages. This makes it possible to "click back via a link" in the final product. (Via a Summa-xslt, it will be set so that pages are not searchable in Summa, but they ''will'' be shown when reached via a link from a paper.)
