Glossary

API
The Application Programming Interface is a collection of methods that a software program makes available to allow interaction with other programs.
Claim
In JSON Web Token, a claim is a piece of information about a subject, structured as a key/value pair.
CSV
CSV stands for Comma Separated Value, and is a file in which the content is organised in a fixed number of fields per line, separated by a comma (,) or some other symbol, like a semi-colon, a slash, or a vertical bar.
Data Format
Data format is the way information is encoded and exchanged between applications.
Data Provider
A Data Provider is an entity that supplies data or datasets to the Open Data Hub. See detailed description.
Dataset
A dataset is a collection of records from a Data source.
Domain
A domain is a category of interest to which one or more datasets belong to.
Endpoint
An Endpoint is an online resource that make data available, usually through REST APIs.
JSON
The JavaScript Object Notation is a lightweight data format to ease the exchange of data between computer and its understanding for humans. Essentially a JSON file is a sequence of key-value pairs, organised into lists (arrays, sequences, vectors). Nesting of key-values and of lists is supported.
JSON Web Token
It is a mechanism to exchange a claim between two parties, used for authentication purposes when the claim is digitally signed and/or encrypted.
Key-value
Also called name-value pair or attribute-name pair, a key-value pair is a simple data structure in which information are stored as tuples {attribute, value}, with no constraint of uniqueness on both attribute and value.
ODHtags
In the tourism domain, this name refers to all the tags/filter that refer to data that have been validated by the Open Data Hub team.
REST API
RESTful API
A REST(ful) API is a Web Service that adheres the architectural constraint of a RESTful system. It is composed of a URI, a collection of methods to interact with the resources offered by the Web Service, and a media type defining the accepted data formats.
Sensor
Within the Open Data Hub, a sensor is intended as a kind of device that gathers data and sends them to another device which stores them in a machine-readable format, used to exchange or publish them. Depending on the domain a sensor may collect environmental data in the mobility domain (like, e.g., temperature, humidity, pressure), but in the tourism domain a sensor can collect the guests in a hotel or the people attending at an event. In these cases, the device is usually a human (e.g., the hotel’s receptionist and the organiser of the event), and the data are digitalised manually.
Statistical Graphics
Statistical graphics are means to display statistical data with the purpose to ease their interpretations. Common statistical graphics include pie charts, histograms, and scatter plot.
Web Component
A Web Component is a set of API that allows the creation of interoperable HTML widgets that can be shared and reused.
