Record representing one involvement — an ongoing role and/or a body of discrete contributions to a single upstream.
tid
Timestamp-based ID
Properties
agentRef
ref
id.sifa.defs#agentRef
Optional
The upstream project, community, event, or cause, as a single nested reference mirroring the flat upstream / upstreamDid / entityRef fields. Additive dual-write: the flat fields remain the source of truth for existing consumers.
collaborators
array
of
ref
id.sifa.defs#projectMemberRef
Optional
Other people who worked on this alongside you. Each entry is a claim by the record author and is not self-verifying: the named person supplies the other half by publishing an id.sifa.confirmation record whose subject is this record and whose relation is id.sifa.defs#collaborator. Until they do, consumers must render the entry without their display name, avatar, or profile link. Confirming never puts this record on their profile: it lives in the author's repository and the author can rename it at any time.
maxLength: 50 itemscreatedAt
string
datetime
Required
Client-declared timestamp when this record was originally created.
description
string
Optional
What the user did and why it mattered.
maxLength: 50000 bytesmaxGraphemes: 5000 graphemesendedAt
string
Optional
End date in YYYY-MM or YYYY-MM-DD format. Omit if ongoing.
entityRef
string
uri
Optional
Portable, app-neutral identifier for the upstream the user selected from a resolver dropdown: a Wikidata Q-ID URI (http://www.wikidata.org/entity/Q...), a ROR URI, or an LEI URI. Enables deterministic resolution to a canonical entity even before the upstream claims an ATproto account. Absent for free-text or one-off entries.
isPrimary
boolean
Optional
Whether this is the user's primary current involvement, surfaced in profile Highlights. Only ongoing entries may be primary.
kind
string
Required
The nature of the involvement. Drives the display heading (Open Source / Community / Volunteering / Civic).
id.sifa.defs#involvementOpenSource, id.sifa.defs#involvementCommunity, id.sifa.defs#involvementCharity, id.sifa.defs#involvementCivic, id.sifa.defs#involvementOtherlabels
union
Optional
Self-label values for this record.
links
array
of
ref
id.sifa.defs#artifactLink
Optional
Public artifacts proving the involvement (PRs, releases, talk recordings, published translations).
maxLength: 50 itemslocation
ref
community.lexicon.location.address
Optional
Where the involvement takes place. Sifa enforces ISO 3166-1 alpha-2 country codes at the app layer.
role
string
Optional
The user's role (e.g. 'Maintainer', 'Translator', 'Organizer', 'Contributor').
maxLength: 2560 bytesmaxGraphemes: 256 graphemessameAs
ref
id.sifa.defs#externalRecordRef
Optional
The same involvement as recorded on another person's profile. Set when you keep your own entry for work someone else has also recorded, so consumers can tell the two describe one thing rather than showing it twice. Each side stays its own record: the other person cannot edit yours, and yours does not change theirs. Resolve by AT-URI, since they will keep editing their copy.
skills
array
of
ref
id.sifa.defs#skillRef
Optional
Skills demonstrated by this involvement. Each entry is a URI reference to an id.sifa.profile.skill record owned by the same DID.
maxLength: 50 itemsstartedAt
string
Optional
Start date in YYYY-MM or YYYY-MM-DD format. Freeform (NOT strict datetime) to allow partial dates and importer writes.
upstream
string
Optional
Name of the project, community, event, or cause (e.g. 'atproto', 'Linux kernel', 'PyCon NL'). Optional — a one-off contribution need not name an organization.
maxLength: 2560 bytesmaxGraphemes: 256 graphemesupstreamDid
string
did
Optional
DID of the upstream's ATproto account, if one exists.
upstreamUrl
string
uri
Optional
Primary URL of the upstream (project homepage, repo, event site).
