Knowledge Organization
From KOP (Knowledge Organization Process) to KOS (Knowledge Organization System).
ER MODEL
The Entity-Relationship model describes interrelated things of interest in a specific domain of knowledge. A basic ER model is composed of entity types (which classify the things of interest) and specifies relationships that can exist between entities. We drew two different models as representation of the desire to highlight the evolution of understading that we have had.
METADATA ANALYSIS
Our analysis of metadata standards was carried uot through both the identification and the choice of the standards used by cultural institutions. Indeed in some cases we decided to keep the actual standards used by the cultural institutions owning our selected items, while for other items we have chosen the most suitable standards for describing them among those generally used in the cultural environment. In both cases, the aim was the same: identifying the right descriptive metadata standards.
METADATA ALIGNMENT
The metadata alignment is thought to show the relationships between the metadata of the items and their standards (introduced in the metadata analysis).
THEORETICAL MODEL
The Theoretical Model is the most theoretical scheme of our representation and its scope is to describe all of the selected items and related information.
CONCEPTUAL MODEL
Our conceptual model appears to be the result of the merger of our two theoretical model, thus considering and connecting both the items and the entities involved in our project, maintaining an event-based perspective. The choice of the vocabularies and ontologies supposed to describe our domain was carried out with the aim of being as specific and descriptive as possible, thus we picked general-use standards such as schema and dbpedia for their highly specific classes and properties, besides re-using well-known and authoritative ontologies used in the LAM domain.
