| 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. |
