…this talk

extension, plugin, add-on
Focused addition, new feature
library
multiple different additions, collection
framework
often built on top of 3rd party software, usually comes with a paradigm / structure / pattern

Sometimes the boundaries are blurred and there is a fluid transition

Motivation

Why?

  • OpenLayers doesn't have everything
  • What else is there on the market?
  • There is a lot out there!
  • Impact of decisions for own projects
