ESciDoc Content Models

UNDER CONSTRUCTION

Definition and scope

Content model (CModel) is a formal representation of set of structural, integrity, behavior rules associated with content resources managed in an eSciDoc repository.

• in eSciDoc content resources are categorized in several primary types: Item, Container, Context, OrganizationalUnit etc.
• in eSciDoc the CModel scope is at the moment limited to resources of primary type Item or Container.

Note: The primary types are subject to extension in eSciDoc.

eSciDoc Primary types

• are complex data structures holding the content resources of an eSciDoc repository and managed via respective resource handler i.e. ItemHandler, ContainerHandler, OrganizationalUnits Handler etc.)
• represent the highest level of generalization of eSciDoc resources (i.e. Organizational Units, Contexts, Items, Containers, Users, etc.)
• may be further specialized by use of a CModel definition

Note: at present only Items and Containers are subject to CModel specialization

What cModel defines

Each CModel is itself a resource in a eSciDoc content repository and as such should have some common properties (applicable for all resources in the repository). Note: at present there is not yet a namespace for common properties of all resources. Once this is done, the properties will become native part of each CModel resource as well .

Each CModel defines a set of configuration properties for the handling of content objects (i.e. Items, Containers) that are specialized with that particular CModel.

• metadata-profiles: references to the metadata profiles
  • in this case still needs to be clarified if there are more than single metadata profile applicable to an e.g. item of a specific CModel
• specific-object-properties: (property-name, property-type, multiplicity)
• component-types: types, multiplicity and format of files which can be associated with Items of particular CModel
• container-

Under consideration at present:

• publishing-method: todo
• pid-assignment-method: todo
• withdrawal-method: todo
• relations: todo (probably not necessary in content model definition)
