The implementation of dynamic metadata tables using the Java programming language together with an object-relational mapping system, Hibernate, is described in the Appendix.
It is obvious that distinct imaging techniques produce different types of raw image data and that the implementation of data and metadata standards will be of critical importance for the success of a morphological database.
The caDSR is an implementation of the ISO/IEC 11179 standard for metadata registries, so we created a mapping between UML and ISO/IEC11179 at the metamodel level.
First, we provide a description of the Metadata Repository (MDR) implementation and SQIV.
In addition, we introduced the concept and early implementation of ontology-based metadata in order to demonstrate the role that context plays in clarifying hierarchical and schematic relationships between like but non-equivalent semantic terms in different databases.
Based on incremental design and implementation of the prototype system (step 3 of the research method [40]), the metadata management layer has been extended (step 4) and evaluated (step 6) in this work.
The main contribution of this work is presentation of the metadata management layer for big data systems (Fig. 12), which has been validated with an implementation.
Our implementation of the EdMate incorporates 31 metrics for measuring the quality of content metadata, which we designed based on data quality principles [38, 40, 41].
EMF has the advantage that the implementation of the objects specified in an ecore model, described in XMI (XML Metadata Interchange), can have their classes automatically generated, facilitating the implementation of the model within an application.
