🪄 (all the minutes) Hack together!

Form teams from the ideas generated in the step above!

Breakout rooms

• Lobby: Symbology

💬 (10 minutes) Share out

Think about: What exciting things did you accomplish? What loose ends remain? Big questions? Big ideas?

Please write for people who don’t have full context; link to related issues and documentation!

• Symbology
  • Plan to use Vega Expressions instead of OpenLayers in the vectorlayer.json - open an issue for this!
  • Could use the descriptions around symbology information developed / described by Sam (software engineer at DSE) to inform how the schema is structured and / or described
    • Let Sam know his data visualization class slides are 404ing
  • Have some example project files bundled with the project and want to validate that they’re obeying the schemas in CI - every time a PR is opened, want to make sure those aren’t broken
  • Need to improve heatmap schema - maybe in the next PR
  • Think about the schema levels of abstraction – should we extract symbology schemas into their own schema sub-directory instead of bundling them with the layers schemas? This will be especially important once we start discriminating between point, line, and polygon sub-types of vector layers because we’ll have an explosion of schema possibilities and we’ll want to drive the form generation more from the schema and less from the JavaScript.
  • How to do JSONSchema definitions and reference them across files?
  • Consider creationform.tsx -> layerCreationForm.tsx?
  • Next steps:
    • Create new form class that inherits from baseform, symbologyForm.
    • Move logic from symbologyDialog -> the new symbologyForm base component.
    • A starting point may be to use BaseForm in the SymbologyDialog module.
      • Look at creationform and debug/log to see what we pass to LayerForm on line 220 to better understand the implementation.
    • MAY need to register our schema in the formSchemaRegistry!
      • There’s a registerSchema function, but it seems we never call it? Is it dynamically called in the generated code?
• TODO: Form property syncData -> submitCallback?
• TODO: Docs on schema -> TS/Py types generation
