RECO Semantic Web Services
This Semantic Web Services allow the retrieval of data stored in Resource Description Framework (RDF) triples that are aligned
with Simple Knowledge Organization System (SKOS) to provide a knowledge representation of RECO vocabularies in order to allow machine processing on a global scale.
Semantic web services are built around universal standards for the interchange of semantic data, which makes it easy for programmers to combine data from different sources and services without losing meaning.
Terminology
W3C - The World Wide Web Consortium, the main international standards organisation for the World Wide Web.
RDF - The Resource Description Framework is a family of W3C specifications
for making statements about resources on the World Wide Web in the form of “subject‐
predicate‐object” expressions, known as triples.
SKOS - Simple Knowledge Organization System. A W3C recommendation for
the representation of knowledge in a format understandable to computers. SKOS is built on top
of RDF.
DC - The Dublin Core Schema is a small set of vocabulary terms that can be used to describe web resources (video, images, web pages, etc.), as well as physical resources such as books or CDs, and objects like artworks.
OWL - The Web Ontology Language (OWL) is a family of knowledge representation languages or ontology languages for authoring ontologies or knowledge bases. The languages are characterized by formal semantics and RDF/XML-based serializations for the Semantic Web.
Collection and concept
A notion of a SKOS collection is useful where a group of concepts shares something in common, and it is convenient to group them under a common label.
Collection are synonymous with code type lists in RECO.
The notion of a SKOS concept is useful when describing the conceptual or intellectual structure of a knowledge organization system,
and when referring to specific ideas or meanings established within that system. Concept are synonymous with code lists in RECO.
Collection and concept are presented to the Server as Uniform Resource Identifiers (URIs), or in this case actually URLs, in the following syntax.
https://vocab.ices.dk/services/rdf/collection - retrieves a SKOS collection of code types.
https://vocab.ices.dk/services/rdf/collection/modified - retrieves a SKOS collection of code types that have been modified after a date.
https://vocab.ices.dk/services/rdf/collection/codetype - retrieves a SKOS collection of codes for the given code type.
https://vocab.ices.dk/services/rdf/collection/codetype/modified - retrieves a SKOS collection of codes for the given code type that have been modified after a date.
https://vocab.ices.dk/services/rdf/collection/codetype/code - retrieves a SKOS collection for the given code and code type.
