Roughly the specification consists of 2 parts: 1. A schema (in essence DCAT) specifying a serialization of Dataset information, and 2. A protocol / API for getting this information from a compliant data catalogue site.
ISO 2146 (Registry Services for Libraries and Related Organisations) is an international standard currently under development by ISO TC46 SC4 WG7 to operate as a framework for building registry services for libraries and related organisations. It takes the form of an information model that identifies the objects and data elements needed for the collaborative construction of registries of all types. It is not bound to any specific protocol or data schema. The aim is to be as abstract as possible, in order to facilitate a shared understanding of the common processes involved, across multiple communities of practice.
This diagram depicts a spectrum of information sharing capabilities. Moving from lower right to upper left of the diagram, we see that more expressive forms of metadata and semantic modeling encompass the simpler forms, and extend their capabilities. From
