Data Structures#
Triplet graphs similar to linked data fragments with envelopes. decoupling content addressing from versioning
Merkel DAGs
Envelopes
Versioning
Typed objects with formatting
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.
Triplets#
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.
