#ActivityPub #OSM #fedigeo #geosocial

Currently I am finishing the OpenStreetMap to ActivityPub / JSON LD module.

The `type`, `context`, ìcon`, `nameMap`, `url` and location parts are ready.

Now it is a giant puzzle to transform all the OSM tags and in particular to make a nice i18n `summaryMap` and `contentMap` text out of it.
So, if you know simmilar projects, please let me know
¯\_(ツ)_/¯

I wonder how much space would it take to store a copy of all my toots + replies in an . Or even of all my timeline. I don't need to cache the images. The goal would be to be able to search my past conversations locally. Unfortunately given that doesn't support 's C2S it would have to work against Mastodon's API

Two #ActivityPub fixes I submitted to #Misskey are in the latest release. I am so amped to see this happen; I cannot emphasize enough how important it is for established #Fediverse platforms to support the ActivityPub spec correctly. I love seeing this happen. Thank you Misskey for making the Fediverse a slightly easier place to write software!

Recently, the Court of Justice of the European Union (CJEU) delivered a new ruling, Russmedia, that has massive implications for how platform regulation and liability work in the EU...

One of the main outcomes of the ruling is that a Romanian online marketplace “is required to implement appropriate technical and organisational security measures in order to prevent advertisements published there and containing sensitive data, in terms of Article 9(1) of that regulation, from being copied and unlawfully published on other websites.” ...

...the problem here is two-fold: First, the ruling is written in a way that can be generalised beyond only Romanian online market places, and into pretty much all platforms that fall under GDPR and handle social data. Secondly, copying and publishing data on other websites is exactly what federation is. The function of open social networking protocols like ActivityPub and atproto at their core is to have social data be copied and published on other websites.

This is an uhhh, slight bit of a problem, when European legal rulings make it very unclear if federation itself is in compliance with GDPR. ...

Kleines Fediverse-Mysterium: Ich folge jemandem auf einer Pixelfed-Instanz, antworte über Mastodon, die Person sieht es auf Misskey – und alles funktioniert einfach so. ✨

Stell dir vor, du könntest einer Gmail-Adresse von Outlook aus schreiben. Ach warte, das geht ja auch. Nur bei sozialen Netzwerken haben wir das irgendwie 15 Jahre lang vergessen. 🤔
