org.apache.stanbol.entityhub.servicesapi.model.Representation
This interface is used by the Entityhub to define representations. It is used for any kind of CRUD operations on the {@link Yard} (the storage of the Entityhub).
The goal if this interface is to allow implementation based on different storage solutions such as CMS, full text indices, triple stores, noSQL data stores ...
TODO: handling the differences between "NaturalLanguageText", "References" and "normal" values feels to complex! Need to reevaluate if this differentiation is needed or can be done in a more easy way! TODO: add an API that allows to attach Content! TODO: Do we need subNodes or are "references" enough. TODO: Check to use also Wrappers for fields and values (in analogy to {@link Reference} and {@link Text}. PRO: clearer API CON: more Objects to be garbage collected. @author Rupert Westenthaler
