Hypercerts

Semantic & Data Protocol

An open protocol for tracking, evaluating and funding impact work. Impact claims ("hypercerts") and their parts — contributions, rights, work scope, evidence attachments, measurements, evaluations, acknowledgements, collections and a governed tag vocabulary — are defined as AT Protocol Lexicon schemas and live as records in repositories their authors control, not on a blockchain. Anyone can review, vouch for, or back a claim.

Semantic & Data Protocol Attributes

Origins Funding and rewarding positive impact: a shared, portable format for impact claims and the evidence and evaluations around them; the project moved its records from blockchain to AT Protocol
Database AT Protocol repositories controlled by each record's author
Query Language Not stated by the project.
Data Formats AT Protocol Lexicon JSON records; CEL expressions for work-scope tags
Collaborative Live Editing N/A — protocol / schema definitions
Rich Text Editing N/A — protocol / schema definitions
Mobile Support N/A — schema layer; client applications vary
Web Support Yes (hypercerts.org website; client applications are separate)
Native Apps N/A — schema layer
Terms Free, open source (MIT / Apache-2.0)
Funds Not stated by the project.
Based On AT Protocol (Lexicon schema language, repositories); earlier on-chain hypercerts work
Semantic Web Compatibility Not stated by the project (AT Protocol Lexicons, not RDF).
Protocol Maturity / Standardization Community Standard / in development (lexicon v1.6.0; several components under development)
Vocabulary / Ontology Type Lexicon schema vocabulary for impact claims, evidence and evaluation (activity, contribution, rights, work scope, measurement, evaluation, attachment, acknowledgement, collection, tag, feature, location, funding)
Usage Pattern Embedded in applications (records written to and read from AT Protocol repositories by apps and funders); Trustgraphs consumes them in its Hypercerts program
