Spaces and Nodes for media data controls and organisation

Description

The Span project is a kind of CMS (Content Management Software) for media instruments.
It works with notion of project which could be highly customized for each of them, or/and could run local patches and use distant existing namespace (in localhost or with a network).
It has a powerfull mapping engine and is natively Open-Sound-Control. It could be used with a lot of protocols such as OSC, MIDI, DMX, ARTNET, SERIAL, VISCA, PJLINK, MINUIT, COPERLAN and more…

The project concept

A SPAN project file is a JSON that have multiples index and dictionaries. This format has been choose for its fastness and simplicity. However, a special syntax is needed, and we could use this online viewer to read it or another JSON viewer. A lot of little utilities should be easily found over the web.

  • Project load :
    • If previous path : Check if a project file is in the specified path (span_project.json).
    • if none : Create a temp folder in span main folder and create a project in from the empty template.
