I've been dabbling with WTherion, and while it is progressing well and looking very good in many respects, it is flagged as a sort term interim project (on Matrix <https://app.element.io/#/room/> ) and I see some high-level challenges: * it seems a document must be saved in three places for it to be an enduring part of a mapping project: * a browser cache (required, and visible only to a particular browser on a particular device) * a json file (if you want to store or share the document (presumably) without loss of fidelity) * a th2 file (if you wish to compile the document using Therion) * In a multi-user project, unless everyone uses the workflow [WTherion open json, edit, export th2, compile Therion] there will be loss of fidelity. ie if some users choose [XTherion open th2, edit, compile Therion] then the WTherion users must 'know' to import from th2. This will result in loss of fidelity, especially where there are xvi files in the th2. For me multi-user and version-controlled storage are prerequisites for any mapping projects, and because it seems for most users, (readers of this forum excepted of course) both Therion and version control are significant challenges, any drawing editor should fit seamlessly into the existing Therion environment. Most likely this means it should read and write th2 files natively. Please tell me if I am wrong. As a self-taught dabbler I am only too happy to be shown the error in my thinking. Anyway, I got to thinking about Mapiah. I think the development for Mapiah is here and was last updated in February? https://gitlab.com/rsevero1/mapiah/-/releases I installed 0.0.3 and it looks like it is still in the very early stages. Is it still under consideration for further development? Bruce
