Overview​

Chive (chive.pub) is a decentralized eprint service built on ATProto. It hosts scholarly publications as ATProto records, with full metadata (authors, abstract, venue, DOI).

Integration Pattern​

Layers provides two integration points for Chive:

  • pub.layers.eprint.eprint connects Layers data (corpora, annotation layers, model outputs) to specific Chive eprints by identifier or AT-URI, and pub.layers.eprint.dataLink records reproducibility metadata (code URI, commit hash, random seed) for the data an eprint produced. (Chive-specific eprint linking previously in pub.layers.chive#eprintDataLink has been absorbed into the general-purpose pub.layers.eprint namespace.) The eprint record now carries a structured citation (pub.layers.eprint.defs#citation) alongside the identifier, holding rendered bibliographic metadata (authors, title, venue, year) as a raw string and/or structured CSL-JSON/DataCite fields. See CSL-JSON, BibTeX, and DataCite for the field mappings. The eprintIdentifier/eprintIdentifierType pair remains the canonical link key.
  • pub.layers.graph.graphEdge connects individual Layers objects (annotations, expressions) to Chive knowledge graph nodes via edges with types like grounding, instance-of, or denotes.

Expressions can also reference eprints directly via eprintRefs, an array of AT-URIs:

{
  "$type": "pub.layers.expression.expression",
  "text": "...",
  "eprintRefs": ["at://did:plc:author/pub.chive.eprint/abc123"]
}

The pub.layers.eprint namespace handles both Chive-specific and general-purpose eprint linking for identifiers such as DOI, arXiv, ACL Anthology, Semantic Scholar, and PubMed.

Layers Types Involved​

TypeRole
pub.layers.eprint.eprintLinks corpus/annotation data to eprints (including Chive eprints) by AT-URI, DOI, arXiv ID, or other identifiers
pub.layers.graph.graphEdgeLinks a Layers object to a Chive knowledge graph node (via target.knowledgeRef with source="chive.pub")
pub.layers.expression.expression (field eprintRefs)Direct AT-URI references from an expression to one or more eprints

Discovery​

The appview indexes expression.eprintRefs and graphEdge target references. Queries like "find all annotation data linked to this paper" resolve by looking up the eprint's AT-URI across all indexed Layers records. Knowledge graph links to Chive nodes are discoverable by indexing graphEdge targets with knowledgeRef.source="chive.pub".
