ESciDoc Content Models
UNDER CONSTRUCTION
Definition and scope[edit]
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[edit]
- 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[edit]
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 the following for respective content resources (Items, Containers) associated with it:
- Metadata profile
- A reference to a metadata profile with which a content resource can be described
- 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-

- withdrawal-method: todo
- relations: todo (probably not necessary in content model definition)
