1. A method comprising: receiving, with a context assembly device, a request to assemble a pedigree that describes a history of origin of a primary resource, wherein the requested pedigree of the primary resource represents the history as a set of statements that describe relationships between the primary resource and a plurality of other resources from which an asserted fact of the primary resource was derived; submitting, from the context assembly device to a set of one or more pedigree management servers, a first query for a first set of pedigree fragments that each include one or more statements that specify direct relationships between the primary resource and a first set of resources, wherein the direct relationships indicate that the asserted fact of the primary resource was derived from data of the first set of the resources; receiving, in response to the first query, a first set of pedigree fragments, each of which includes one or more of the statements that specify the direct relationships between the primary resource and the first set of resources; submitting, with the context assembly device to the pedigree management servers, a second query for a second set of pedigree fragments that include one or more statements that specify direct relationships between the first set of resources and a second set of resources, wherein the direct relationships of the second set of pedigree fragments indicate that the data of the first set of resources was derived from data of the second set of the resources; receiving, in response to the second query, the second set of pedigree fragments, each of which includes one or more of the statements that specify the direct relationships between the first set of resources and the second set of resources; and assembling, with the context assembly device, the pedigree of the primary resource from the statements of the first set of pedigree fragments and the second set of pedigree fragments received from the pedigree management servers.
