  • .. An attempt to transcend the respective information perspectives of the various communities by adopting and open cross-domain Semantic Web based framework that can accommodate the different domain based standards.
  • This is the general picture of what the EDM is designed to support. The bottom layer shows networked objects that may (or may not) be linked to each other by explicit statements in the metadata. The upper layer shows how they can be linked using semantic web technology - by adding a layer of meaning that can be searched to make links that have not been explicitly stated in the metadata – and mostly these links are not made by data provider but by reference to semantic resources such as controlled vocabularies and authority files: in particular we hope to enrich data by additon or links to names and places using VIAF and Geonames.
