Conceptual Model
Definition
A conceptual model is an abstract representation of a system and comprises well-defined concepts, their qualities or attributes, and their relationships to other concepts. A system is a group of interacting or interrelated elements that act according to a set of rules to form a unified whole. The conceptual model can be materialised in a graphical representation facilitating knowledge elicitation, organisation and interaction with domain experts. This is relevant because interactions and discussions within a Working groups are often driven by a graphical representation.
There is no perfect candidate for representing the conceptual model. And, although not without limitations, risks for misunderstandings and mis-interpretations, we choose UML language with visual Paradigm tool as an instruments in addressing (a) the concern for having a conceptual model established and (b) the concern for providing a graphical representation.
Ontology
Definition
An ontology is a a formal specification describing the concepts and relationships that can formally exist for an agent or a community of agents (e.g. domain experts) [gruber]. It encompasses a representation, formal naming, and definition of the categories, properties, and relations between the concepts, data, and entities that substantiate one, many, or all domains of discourse.
Metadata schema
Definition
A metadata schema is a structured framework or set of rules that define how metadata (information about data) is organised and described. Metadata schemas are used to standardised the format and content of metadata for efficient data management and retrieval.
Generic Core model
Definition
A generic core metadata schema is a foundational or template that represents essential elements and relationships common cross-domain. It serves as a basis for developing more a specialised schema. In the context of health-ri and national catalogue, the generic core schema includes a set of minimum metadata requirements common across various working groups (such as Imaging and Omics) that enables the user discover and find a research object (e.g., dataset). in the context of health-ri and for the national catalogue we use dcat and dcat-ap as a core metadata schema [read more here].
