Analysis

Overview

This task is about the base links support that is in the model.

Task requirements

• Create a base model library for support of links. It should provide:
  • single link structure.
  • some utility classes for links, if needed.
  • persistence of links.
  • Links are mainly defined and used with Frames.
    • consider adding functionality to the Frame to support Links.
• Create a wiki page that describes the general design of the links in the model.

Task result

• wiki page.
• source code.

Implementation idea

• see other tasks in the task index that are about links.
• examine Sophie 1.0 links. (see ​http://sophieproject.org/download/, ​http://sophieproject.org/tutorials, ​http://sophieproject.org/node/235 to get some ideas about the design of timelines.)
• create the wiki page and fill in the concepts and design.
• implement the base model support for links in the model.
