ATFISL is a content discovery system for CIDs built with the AT Protocol. Publishers announce download locations for CIDs by publishing records to their AT Protocol repositories. Indexers aggregate these records into a lookup table from CIDs to live locations. ATFISL is complemented by FISL which defines an HTTP query API for ATFISL records.
ATFISL — content discovery with the AT Protocol
How ATFISL publishes CID locations as dev.fisl.at records on the AT Protocol: the record, the record key, the Lexicon, and indexing.
DASL: FISL — Finding Internet Structures & Links
FISL is an HTTP lookup API that maps CIDs to locations, so that a client with a CID can find out where to retrieve it from and who announced it. A client sends a CID, and the index returns the URLs where content can be retrieved, along with the identity of the publisher when known. FISL specifies only the query interface, so it works with any indexing system that supplies location records.

FISL — Finding Internet Structures & Links
FISL is an HTTP lookup that maps a CID to the URLs it can be fetched from. ATFISL publishes those locations on the AT Protocol.
DASL: RASL — Retrieval of Arbitrary Structures & Links
RASL is a URL scheme used to identify content-addressed DASL resources along with a simple HTTP-based retrieval method.

DASL — Data-Addressed Structures & Links
A small set of simple, standard primitives to work on content-addressed data.

DASL: MASL — Metadata for Arbitrary Structures & Links
MASL is a CBOR-based metadata system that is designed to work well with content-addressed and decentralised systems, to enable fully self-contained, self-certified content distribution.

Streaming Data - AT Protocol Docs - AT Protocol
Synchronizing and streaming data from the AT Protocol.

DASL: Content-Addressable aRchives (CAR)
The CAR format offers a serialized representation of set of content-addressed resources in one single concatenated stream, alongside a header that describes that content.

About — AT Proto Collection Tracker
A bottom-up tool for discovering activity across the AT Protocol network by watching live record types on the Jetstream firehose.
DASL: DRISL — Deterministic Representation for Interoperable Structures & Links
DRISL is a serialization format that is deterministic (so that the same data will have the same CID) and that features native support for using CIDs as links. It is based on CBOR, using a narrow profile of CBOR's "Core" featureset called "[[cborc-42]]", specified formally in this IETF document.


Welcome to the new Aturi... a suite of tools for touring the Atmosphere & exploring the AT Protocol. 1. Explorer — Inspect the data inside every account 2. Extension — Switch apps in 1 click (or zero), detect URIs, inspect data 3. Universal Links — Share content, let them pick a client aturi.to
Aturi is a new service that provides universal links for traversing/sharing content in the ATmosphere. Share @bsky.app posts or @atproto.com data with in a way that lets recipients choose where they want to view it — @blackskyweb.xyz, @leaflet.pub, @anisota.net, @pdsls.dev, and more! aturi.to
