Definition: Knowledge Triplestore ABB is a Data Object that enables storage, management and retrieval of data in the form of triples, data entities composed of subject-predicate-object. Source: W3C Source reference: https://www.w3.org/2001/sw/Europe/events/20031113-storage/positions/rusher.html Example: The following implementation is an example on how this specific Architecture Building Block (ABB) can be instantiated as a Solution Building Block (SBB): CELLAR. Cellar metadata is stored in a knowledge graph, and more specifically in a triple store. A SPARQL interface is used to query the metadata. https://op.europa.eu/en/web/cellar/cellar-data/metadata/knowledge-graph eira:iopDimension: Structural IoP LOST view: TVA-Functional Architecture Principles eira:iopSaliency: The Knowledge Triplestore Data Object ABB is salient for technical interoperability because it represents the different data objects such as databases storing data, allowing to manage and retrieve of data from different sources and digital public services.
