Background

The use of metadata has been raised several time during the project and since this project is about Linked Open Data, we will definitely come to using one or more standards.

The aim of this discussion is

  1. to identify suitable metadata standards
  2. decide in which part of the system / for which objects a certain standard should be used

2 Application of Metadata Standards

Dublin Core

Since DC is for describing the properties of a document or resource (such as title, author, dateAccepted, relates) it seems to be a good standard for describing our Decks (and Slides). 


Schema.org

Since Schema.org aims to provide a general purpose (can one call it world-knowledge) vocabulary it seems to be a good standard for describing the contents of Slides.

Metadata can also help Accessibility
