    Yes. I posted something on the same subject today.

  • @eyeinthesky The reason we can't have nice things is because the Fedi Devs don't want to deal with the basics of the protocol. Or: Because no one has yet provided C2S for Fedi Devs who don't want to deal with the basics.

  • @cwebber @eyeinthesky @smallcircles @evan Apart from the fact that I would prefer turtle, I am very happy that AP ‘prescribes’ json-ld. This opens the door to many of my ideas. It makes possible what would be very complicated without . It's about time that the AP developers got to grips with it! https://rdf-pub.org/#rdf

  • @eyeinthesky @smallcircles @evan To be clear, I think json-ld has a lot of great ideas in it, and it's the extensibility and linked data compatibility (which was a strong group requirement) story we had at the time.

    "JSON-LD is bad" doesn't really capture my views. "JSON-LD turned out to be too complicated for the majority of the ecosystem to work with, particularly when we gave the view that you could ignore it, except it creates a rift of interoperability between those who ignore it and those who don't and puts a burden on the latter who are doing their best to behave well" does match my views.

    There are paths out of the situation, but I'm not confident in the discourse around them right now, and hesitant about how much I want to engage with it.

    Here we come to my new interest area.. I spent a metric ton of time advocating for and and that was initially all on a very optimistic note on how our ecosystem would mature and grow over time, fostering a healthy future for itself.

    That however didn't go as planned. You might say that the entirety of the fediverse is still primarily tech-driven. Tech-first approaches that do not differ too much of the much reviled and rejected 'techbro approach'.

    Sure, there are plenty discussions on whether an app feature is 'ethical' or not, with discussions on e.g. opt-in vs. opt-out. But that is again purely app-centric.

    Where is the dev ecosystem headed, where should they focus, what externalities exist? Where do we want future as a whole to be? What's the vision?

    And then we come to the social side of things, both in the small, but also in-the-large. Technosphere aligned and subservient to Sociosphere. That is focus of https://coding.social

  • @smallcircles “an interpretation that advocates for tolerating unexpected inputs is no longer considered best practice in all scenarios.” Somebody didn’t get the memo. lol

    There are a couple of really great documents on protocol design and maintenance. You often see me mentioning protocol decay, which is only a paragraph in the splendid Maintaining Robust Protocols.

    The next section for instance is on detrimental ecosystem effects if you are either too stricly enforcing standards or are too laissez faire about them.

    The protocol becomes more like the union of all app-specific functionality that has been created over time, and copied / depended on by others in fundamental ways. Instead of that all that happens in clear solution layer that rests above the protocol conceptually.

    The protocol boundaries are fuzzy.

    @deadsuperhero mentioned the other day that having identity management well figured out, would be the killer app for the fediverse.

    But without having these fundamentals on how we responsibly 'extend the fediverse' (deploy a new solution, deliver a service), I don't think this is the case. But having that functionality might make it very clear that we need this foundation.

    Now an identity is neatly app-bound, but then no longer and since all apps overloaded the ActivityStreams social primitives you may have to deal with the full combinatorial explosion of figuring out what the functionality of your as:Video or other object really is.

    Perhaps I see it wrong.

    Fedify 1.10.0: Observability foundations for the future debug dashboard Fedify is a #TypeScript framework for building #ActivityPub servers that participate in the #fediverse. It reduces the complexity and boilerplate typically required for ActivityPub implementation while providing comprehensive federation capabilities. We're excited to announce #Fedify 1.10.0, a focused release that lays critical groundwork for future debugging and observability features. Released on December 24, 2025, this version introduces infrastructure improvements that will enable the upcoming debug dashboard while maintaining full backward compatibility with existing Fedify applications. This release represents a transitional step toward Fedify 2.0.0, introducing optional capabilities that will become standard in the next major version. The changes focus on enabling richer observability through OpenTelemetry enhancements and adding prefix scanning capabilities to the key–value store interface. Enhanced OpenTelemetry instrumentation Fedify 1.10.0 significantly expands OpenTelemetry instrumentation with span events that capture detailed ActivityPub data. These enhancements enable richer observability and debugging capabilities without relying solely on span attributes, which are limited to primitive values. The new span events provide complete activity payloads and verification status, making it possible to build comprehensive debugging tools that show the full context of federation operations: activitypub.activity.received event on activitypub.inbox span — records the full activity JSON, verification status (activity verified, HTTP signatures verified, Linked Data signatures verified), and actor information activitypub.activity.sent event on activitypub.send_activity span — records the full activity JSON and target inbox URL activitypub.object.fetched event on activitypub.lookup_object span — records the fetched object's type and complete JSON-LD representation Additionally, Fedify now instruments previously uncovered operations: activitypub.fetch_document span for document loader operations, tracking URL fetching, HTTP redirects, and final document URLs activitypub.verify_key_ownership span for cryptographic key ownership verification, recording actor ID, key ID, verification result, and the verification method used These instrumentation improvements emerged from work on issue #234 (Real-time ActivityPub debug dashboard). Rather than introducing a custom observer interface as originally proposed in #323, we leveraged Fedify's existing OpenTelemetry infrastructure to capture rich federation data through span events. This approach provides a standards-based foundation that's composable with existing observability tools like Jaeger, Zipkin, and Grafana Tempo. Distributed trace storage with FedifySpanExporter Building on the enhanced instrumentation, Fedify 1.10.0 introduces FedifySpanExporter, a new OpenTelemetry SpanExporter that persists ActivityPub activity traces to a KvStore. This enables distributed tracing support across multiple nodes in a Fedify deployment, which is essential for building debug dashboards that can show complete request flows across web servers and background workers. The new @fedify/fedify/otel module provides the following types and interfaces: import { MemoryKvStore } from "@fedify/fedify"; import { FedifySpanExporter } from "@fedify/fedify/otel"; import { BasicTracerProvider, SimpleSpanProcessor, } from "@opentelemetry/sdk-trace-base"; const kv = new MemoryKvStore(); const exporter = new FedifySpanExporter(kv, { ttl: Temporal.Duration.from({ hours: 1 }), }); const provider = new BasicTracerProvider(); provider.addSpanProcessor(new SimpleSpanProcessor(exporter)); The stored traces can be queried for display in debugging interfaces: // Get all activities for a specific trace const activities = await exporter.getActivitiesByTraceId(traceId); // Get recent traces with summary information const recentTraces = await exporter.getRecentTraces({ limit: 100 }); The exporter supports two storage strategies depending on the KvStore capabilities. When the list() method is available (preferred), it stores individual records with keys like [prefix, traceId, spanId]. When only cas() is available, it uses compare-and-swap operations to append records to arrays stored per trace. This infrastructure provides the foundation for implementing a comprehensive debug dashboard as a custom SpanExporter, as outlined in the updated implementation plan for issue #234. Optional list() method for KvStore interface Fedify 1.10.0 adds an optional list() method to the KvStore interface for enumerating entries by key prefix. This method enables efficient prefix scanning, which is useful for implementing features like distributed trace storage, cache invalidation by prefix, and listing related entries. interface KvStore { // ... existing methods list?(prefix?: KvKey): AsyncIterable<KvStoreListEntry>; } When the prefix parameter is omitted or empty, list() returns all entries in the store. This is useful for debugging and administrative purposes. All official KvStore implementations have been updated to support this method: MemoryKvStore — filters in-memory keys by prefix SqliteKvStore — uses LIKE query with JSON key pattern PostgresKvStore — uses array slice comparison RedisKvStore — uses SCAN with pattern matching and key deserialization DenoKvStore — delegates to Deno KV's built-in list() API WorkersKvStore — uses Cloudflare Workers KV list() with JSON key prefix pattern While list() is currently optional to give existing custom KvStore implementations time to add support, it will become a required method in Fedify 2.0.0 (tracked in issue #499). This migration path allows implementers to gradually adopt the new capability throughout the 1.x release cycle. The addition of list() support was implemented in pull request #500, which also included the setup of proper testing infrastructure for WorkersKvStore using Vitest with @cloudflare/vitest-pool-workers. NestJS 11 and Express 5 support Thanks to a contribution from Cho Hasang (@crohasang@hackers.pub), the @fedify/nestjs package now supports NestJS 11 environments that use Express 5. The peer dependency range for Express has been widened to ^4.0.0 || ^5.0.0, eliminating peer dependency conflicts in modern NestJS projects while maintaining backward compatibility with Express 4. This change, implemented in pull request #493, keeps the workspace catalog pinned to Express 4 for internal development and test stability while allowing Express 5 in consuming applications. What's next Fedify 1.10.0 serves as a stepping stone toward the upcoming 2.0.0 release. The optional list() method introduced in this version will become required in 2.0.0, simplifying the interface contract and allowing Fedify internals to rely on prefix scanning being universally available. The enhanced #OpenTelemetry instrumentation and FedifySpanExporter provide the foundation for implementing the debug dashboard proposed in issue #234. The next steps include building the web dashboard UI with real-time activity lists, filtering, and JSON inspection capabilities—all as a separate package that leverages the standards-based observability infrastructure introduced in this release. Depending on the development timeline and feature priorities, there may be additional 1.x releases before the 2.0.0 migration. For developers building custom KvStore implementations, now is the time to add list() support to prepare for the eventual 2.0.0 upgrade. The implementation patterns used in the official backends provide clear guidance for various storage strategies. Acknowledgments Special thanks to Cho Hasang (@crohasang@hackers.pub) for the NestJS 11 compatibility improvements, and to all community members who provided feedback and testing for the new observability features.
