3geonames API could be useful as an alternative to the what3words API and H3geo for a universal set of coordinates. As we discussed at the AEC Hackathon, companies like KlokanTech as well as swisstopo and cantonal geo-offices have a lot of experience in this. This is an important part of the conversation around creating a common ontology for Linked Data services for modelling urban spaces, and the hope is we move towards a DNS-like addressing system that is transparently governed, "zoomable" and efficient.

CrossWind ⟵ also has a linked geo database, with ability to time travel across the graph (mentioned by @n0rdlicht during our AEC 2024 hackathon)

Goals

1. Create an account with Speckle.xyz, a new stream and import any Cesium IFC file.
2. Try to read the stream with @speckle/objectloader package
3. See how we can blend this in our IFCDataSource source code within the ‹cesium-ifc-viewer› component
4. Bonus: updated the view when the component changes

Useful resources

• https://www.npmjs.com/package/@speckle/objectloader ⟵ Speckle ObjectLoader package to read contents of a Stream available from Speckle back-end and use it in either a browser (which we want) or Node.js
• https://speckle.xyz/graphql ⟵ allows to interrogate Speckle for the data model of our stream
• https://github.com/specklesystems/speckle-sharp/blob/main/Objects/Objects/Geometry/Mesh.cs ⟵ sample Mesh object of the Speckle data model
• https://speckle.xyz/streams/e6fa820fdd/webhooks ⟵ if we want our back-end to be informed of changes to a stream — but we want our front-end to be informed of changes, as we don't rely on a back-end…
• wss://speckle.xyz/graphql (Subscriptions › CommitCreated) ⟵ and for this, GraphQL Subscriptions come to play
