Agenda discussion 24.11.2008[edit]
Brainstorming[edit]
- Validation
- Classification of objects (typization)
- agreed by all
- CModel should be defined in XML (XSD, Schematron, RDF, RelaxNG, proprietary)
- agreed by all
- (Formal) structure of objects "festlegen"
- agreed by all
- CModels to their digital objects are what classes are to instances
- discussion, MRa point: to stick as much as possible to Fedora CMA and the new developments coming out from Fedora
- questioning why eSciDoc is "hiding" Fedora (besides more complex security model, support for aggregations and object graphs)
- example: OAI-PMH had to be re-worked (eSciDoc have more requirements on set definition and specific version of objects, not last versions, but released versions)
- CModels describe the semantic of instances (textual, context information, content category, metadata profile etc.)
- semantic defined as meaning of objects of certain CModel
- semantic is described with a certain formal structure
- semantic is described by syntax such as XSD, Schematron, RDF etc.
- Define type-specific methods
- all agreed there can be type-specific methods even though not always clear where/how
- discussion on Resource (Object manager) handler
- at end agreed that type-specific methods are not necessarily equal to Fedora disseminators (can be defined by users of the CModel i.e. for purpose of certain solution)
- Container handler is convenient even though it is apparently clear Items are very similar to containers
- independent from the implementation
- interoperable
- inheritance from CModels
- CModels define the behavior of Services (search, Relations, technical metadata-extraction)
- metadata profiles
- allowed relations
- life-cycle (status-transitions, initial status)
- CModel is versioned
- Templates
- File formats
