A standard specifying the identifiers to be used for a particular collection of objects. Using standard vocabularies where they exist is key to enabling data integration. Linked data is rich in vocabularies in different topic areas. Source: ODH

A visual representation of data is often the most compelling way of communicating the data, bringing out its key features, correlations and outliers. Though many tools exist, creating a visualisation for a dataset is not an automatic process, but requires careful attention to the meaning of the variables, the relations between them and the stories inherent in the data, to design a visual representation that lets the message of the data shine through.

The Unicode Standard supports three encoding forms (UTF-8, UTF-16, UTF-32) that use a common repertoire of characters. These encoding forms allow for encoding as many as a million characters. This is sufficient for all known character encoding requirements, including full coverage of all historic scripts of the world, as well as common notational systems. All three encoding forms encode the same common character repertoire and can be efficiently transformed into one another without loss of data.

Uniform Resource Identifier / Uniform Resource Locator. A URL is the http://… web address of some page or resource. When a URL is used in linked data as the identifier for some object, it is not strictly a locator for the object (e.g. http://dbpedia.org/page/Paris is the location of a document about Paris, but not of Paris itself), so in this context it is referred to as a URI.

Data that is more free-form, such as multimedia files, images, sound files, or unstructured text. Unstructured data does not necessarily follow any format or hierarchical sequence, nor does it follow any relational rules. Unstructured data refers to masses of (usually) computerized information which do not have a data structure which is easily readable by a machine. Examples of unstructured data may include audio, video and unstructured text such as the body of an email or word processor document.

An identifier for an object which is guaranteed to be different from identifiers of all other objects in a collection. Within a database, every object will have a UID that is unique within the database. A UID assigned by a central registry (such as an ISBN for books, or a DOI for data) will be unique for all objects for which it is assigned.

The Unicode Standard is a character coding system designed to support the worldwide interchange, processing, and display of the written texts of the diverse languages and technical disciplines of the modern world. In addition, it supports classical and historical texts of many written languages. The Unicode Standard provides a unique number for every character, no matter what platform, device, application or language.

A meeting, similar to a conference, but with no agenda fixed in advance. Using various established techniques, participants jointly agree on the day what sessions will run. Some more traditional conference sessions with invited speakers may also be included. A popular format among the tech community, an unconference can be combined with or run alongside a hackathon based on open data.

A simple text format for a database table. Each record in the table is one line of the text file. Each field value of a record is separated from the next by a tab stop character. It is a form of the more general delimiter-separated values format.
