Untyped Chronicle¶
Chronicle can be used without a domain, for scenarios where you do not need
attributes. chronicle-untyped
is distributed for this purpose.
Except for the lack of attributes and roles, all Chronicle functions are
available - including domain types. Care must be taken with the use of domain
types when using chronicle-untyped
as they are not checked.
Creating an agent in untyped chronicle¶
The untyped creation mutations agent
, activity
and entity
can be used to
create provenance terms. Mutations that produce provenance relations work in the
same way as typed Chronicle.
mutation {
agent(name: "agent",
attributes: {type:"artist"}) {
context
}
}
Querying untyped chronicle¶
The activity timeline can be queried in the same manner as typed chronicle, with
the omission of type filters. Returned prov terms will be of the 'unknown' types
ProvAgent
, ProvActivity
or ProvEntity
. If domain types have been set, then
they will appear on the corresponding type field.
query {
activityTimeline(forEntity: ["http://blockchaintp.com/chronicle/ns#entity:example"],
from: "1968-01-01T00:00:00Z",
to: "2030-01-01T00:00:00Z",
activityTypes: [],
) {
edges {
node {
... on ProvActivity {
id
name
type
wasAssociatedWith {
responsible {
agent {
... on ProvAgent {
id

type
}
}
role
}
}
used {

}
}
}
}
}
}
}
