RDF

In this final step data are described using a RDF statement, that we decided to serialize through Turtle. URIs have been minted for every entity described. In addition, we connected our data to other related items and resources on the World Wide Web by using different types of semantic associations.

We decided to describe three selected and different entities, out of the seven most important of our project, with the aim of representing how connections work between people, places and events.  The entities are:  the Hungarian coronation, a biographical event, Elisabeth of Austria, one of the protagonist of the event, and the Royal palace of Gödöllő , a place related to the entities. The RDF statement is here displayed in the RAW version of its Turtle serialization.   A graphical representation of the RDF triplets and a syntax highlighted version are also provided on the GitHub page of the project.

Semantic web doesn’t consist in just creating an architecture for data, but also and above all, in creating interconnections. In order to create internal connections, we came up with new URIs for each entity, as if they were part of a real Linked Open Data system, and for the items included in the rdf.


Entities:
https://sissilinked.github.io/person/Elisabeth_of_Austria
https://sissilinked.github.io/person/Franz_Joseph_I
https://sissilinked.github.io/person/Luigi_Lucheni
https://sissilinked.github.io/place/Royal_Palace_of_Gödöllő
https://sissilinked.github.io/event/Hungarian_Coronation
https://sissilinked.github.io/event/Assassination_of_Sissi
https://sissilinked.github.io/concept/Imperial_Style

Items included in the rdf:
https://sissilinked.github.io/item/Elisabeth_Coronation_Photograph
https://sissilinked.github.io/item/Family_Lithograph_in_Gödöllő
https://sissilinked.github.io/item/Black_Court_Dress
https://sissilinked.github.io/item/Sissi_The_Young_Empress
https://sissilinked.github.io/item/Black_Laundalet


We also used Authority controlled forms and external resources as a way of associating a unique identifier to the entities and to names of people, places and events, which are external and not described by our model. Every time it was possible to use this form directly, we wrote the name of resource in its controlled form.


GND
The Integrated Authority File is an international authority file for the organisation of personal names, subject headings and corporate bodies created by the German National Library. We made a broad use of it, especially for identifying royal people (i.e. http://d-nb.info/gnd/119446707 for Maria Anna of Savoy), buildings, concepts (i.e. http://d-nb.info/gnd/4004541-9 for Baroque) and countries from an historical, and not only geographical, point of view.

VIAF
The Virtual International Authority File combines multiple name authority files into a single OCLC-hosted name authority service. The goal of the service is to lower the cost and increase the utility of library authority files by matching and linking widely-used authority files and making that information available on the Web.

DBR
DBpedia is a project aiming to extract structured content from the information created in Wikipedia. This structured information is made available on the World Wide Web, allowing the possibility of semantically query relationships and properties of Wikipedia resources, including links to other related datasets.

GEONAMES
GeoNames is a geographical database contains over 25 million geographical names and consists of over 11 million unique features whereof 4.8 million populated places and 13 million alternate names. It provides permanet links for every record. We used them as a way for uniquely identify cities (i.e. http://www.geonames.org/2867714 for Munich), countries and other geographical locations.



Finally, we included properties that would allow the connection to external resources, as the authority forms mentioned above, or others related because of the sharing of one of the features of the described entity. In order to do that, we established different semantic associations from a hierarchical, partitive or associative point of view.
