Word Definition
API Stands for Application Programming Interface. Consists of a set of endpoints.
Endpoint An endpoint is one end of a communication channel. It may refer to a SPARQL endpoint, a standardized interface for public access to databases of LinkedData on the web.
Assistant Refers to the Linked Pipes Visualization Assistant, a predecessor of Linked Pipes Applications, which allows users to create, configure and publish visualisations based on input data sets.
Data descriptor A SPARQL ASK query associated with a visualizer that determines if an input data graph can be visualized in the corresponding visualizer.
Data source Refers to any source of data, such as an RDF file, SPARQL endpoint, csv, database, etc.
ETL Extract, transform, load.
IRI Stands for Internationalized Resource Identifier. It is an internet protocol standard which extends ASCII characters subset of the Uniform Resource Identifier (URI) protocol.
LDVM Stands for Linked Data Visualization Model.
LDVMi Stands for LDVM implementation.
Linked Data a method of publishing structured data so that it can be interlinked.
LPA Stands for Linked Pipes Application.
Linked Open Data Cloud (LOD Cloud) The largest cloud of linked data that is freely available to everyone.
LinkedPipes ETL The service in charge of the ETL process.
Pipeline In the current context, refers to a process in which the application takes any data source and applies a series of transformations to its data based on the desired visualisation.
Pipeline Execution A run of the pipeline on the actual data and handover of the transformed output to a visualizer component, which then produces a visual representation of the data.
Pipeline Discovery A process taking input descriptors for all visualizers and attempting to combine the respective registered transformations to achieve a specific data format.
RDF Resource Description Framework.
Semantic web An extension of the World Wide Web through standards by the World Wide Web Consortium.
Single Page Application (SPA) A web application or web site that interacts with the user by dynamically rewriting the current page rather than loading entire new pages from a server.
SPARQL Stands for SPARQL Protocol and RDF Query Language. It is a query language able to retrieve and manipulate data stored in RDF format.
URI A Uniform Resource Identifier (URI) is a string of characters designed for unambiguous identification of resources and extensibility via the URI scheme. They provide a standard way for resources to be accessed by other computers across a network or over the World Wide Web.
URL A URL is a specific type of URI and stands for Uniform Resource Locator.
