Data Structures#

Triplet graphs similar to linked data fragments with envelopes. decoupling content addressing from versioning

Containers#

Packets of LD-triplets that contain
- Hash of triplets
- Encryption Info (if applicable)
- Permissions scope
- Signature
Anything that can be directly referenced without local qualifier is a container.
- Triplets within a container can be referenced with the query syntax
Containers also behave like “feeds”
- Eg. one might put their blog posts in @user:blog or
The account identifier is the top-level container.
Ordering:
- Every triple within a scope is ordered by default by the time it is declared
- A container can declare its ordering (see vocabulary)
Naming:
- Each container intended to be directly referenced SHOULD contain a name so it can be referenced w.r.t its parent: @<ACCOUNT>:<name>
- Each container can also be indicated numerically
Identity: Each container is uniquely identified by the hash of its contents and the hash of the account identifier.
Format: A container can specify one or several ways it can be displayed
Capabilities: A container can specify different capabilities that another account can take (eg. “Like”, “Upvote”, “Reply”)
- Capabilities should also contain a permissions scope, if none is present, the global scope is assumed.

Triplet format
- Objects require a shortname that can be hierarchically indexed from
Types/Schema
Including intrinsic notion of nesting
- every object can have blank/positionally indexed children
- every triple can have blank/positionally indexed “qualifiers” like RDF-star or wikidata’s qualifiers.
