@smohiudd should we add https://stac-extensions.github.io/render/v1.0.0/schema.json in the stack-extension array?

Yes thanks for the reminder. Will add.

[smohiudd]

@emmanuelmathot are you able to release the render stac extension so we can validate the rendering parameters?

[emmanuelmathot]

Sure. I was expecting a very last approval from your side. I will do the release very soon.

[emmanuelmathot]

Render extension release 1.0.0 : https://github.com/stac-extensions/render/releases/tag/1.0.0

[smohiudd]

Thanks @emmanuelmathot! How can we get the identifier link to work as well? https://stac-extensions.github.io/render/v1.0.0/schema.json

[smohiudd]

@emmanuelmathot also apologies I missed your last collaboration request (it expired) on the renders repo. Can you please add me and @vincentsarago again?

[vincentsarago]

@smohiudd I do not have admin rights to add you :-(

[emmanuelmathot]

Sorry. I think I used a wrong tag for the release. Il will fix it and add you again as maintainers.
