Introduction[edit]
This page provides short introduction into the eSciDoc logical data model. It may be used as reference to understand the high-level structure of the data within an eSciDoc repository. The eSciDoc repository manages two general categories of data:
- Resources (content resources) - the content of the repository such as: articles, book, images, image albums, scanned manuscripts, pages etc. Basic object classes in this group are: Item, Container
- MasterData - additional classes of data that are used for management of Resources. Basic object classes in this group ate Context, OrganizationalUnit, ContentModel
A simple delineation between these two data categories may be stated in the following manner: resources are the real content that can be further extended, shared and preserved. Master data are used for content administration and as referenced entities of importance. Master data can also be referenced by objects outside of the core eSciDoc repository.
Basic classes of objects[edit]
The diagram above describes the overall relations between the basic classes of objects in an eSciDoc repository.
- Item
- Container
