What is SPEEDy?
SPEEDy is a web based standoff property editor that can be dropped into any web application. It aims to provide the basic features of a text editor along with the ability to create user-defined annotations that can overlap freely. The editor can import or export data in a JSON format and makes no assumptions about the back-end data-store. While standoff properties can be stored in any format storing them as LOD entities in a graph database vastly increases their potential.
