Identifying and retrieving graphics

Each graphic, graphical unit, and graphical element has an Internationalized Resource Identifier (IRI), that also serves as a URL, in the form “https://endlessforms.info/<library>/<identifier>”

The information page for each graphic can be obtained by appending “.html” to the IRI. The SVG can be obtained by appending “.svg” to the IRI.

Graphic components

Graphics are developed using a composable methodology. There are three types of components in a graphic library:

• Graphical element: An SVG element of type <path>, <line>, <ellipse>, <polygon>, <polyline>, or <rect>
• Graphical unit: Two or more graphics or graphical units
• Graphic: A complete “ready-to-use” representation composed of two or more graphical elements, graphical units, or graphics

Production pipeline

Our current production pipeline includes design of the graphics in Adobe Illustrator, export as SVG, upload to a database, and rendering on demand using a Ruby on Rails framework.
