Linked Data
Linked data enables users to locate, connect, describe and reuse data of all kinds. Items are identified using URIs, or Uniform Resource Identifiers, and information about these items of data is provided using Semantic Web standards (e.g. RDF). These can be recognized by their subject-predicate-object structure: for example, a monograph (subject) is authored by (predicate) Joe Example (object).
Social linked data
SOLID (social linked data) is often mentioned in connection with the Facebook data theft. Rather than sending a third party an image of themselves, a user can publish a link to the image instead. This enables the user to change or delete the image whenever they want without having to ask the third party. However, this is only possible if the third party exclusively accesses the image via the link and does not download it in order to create their own image collection. Misuse of this method therefore cannot be excluded.
