Dynamic assembly of information pedigrees
First Claim
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.

Abstract
This disclosure describes techniques of dynamically assembling and utilizing a pedigree of a resource. A pedigree of a resource is a set of statements that describe a provenance of the resource. As described herein, a set of one or more servers may host context objects that contain the statements that make up the pedigree of the resource. In order to obtain the pedigree of the resource, a context assembly device may send queries to the servers for context objects that are likely to contain statements in the pedigree of the resource. After receiving context objects from the servers in response to the queries, the context assembly device may query the statements in the received context objects in order to identify, among the statements in the context objects, the statements that constitute the pedigree of the resource. The dynamically assembled pedigree may then be used in a variety of ways.

9. A device comprising:
-
a processor; an interface that receives a request to assemble a pedigree of a primary resource, wherein the pedigree of the primary resource includes a set of statements that describe relationships between the primary resource and other resources from which an asserted fact of the primary resource was derived; a first-stage query module executing on the processor that submits to a set of one or more pedigree management servers a first query for pedigree fragments that include one or more statements that specify direct relationships between the primary resource and a first set of the 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; wherein the interface receives, in response to the 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; and a second-stage query module executing on the processor that queries the first set of pedigree fragments to identify statements that describe direct relationships between the primary resource and a second set of the resources, wherein the first-stage query module is configured to submit a second query to the pedigree management servers to obtain a second set of pedigree fragments that include one or more statements that specify direct relationships for the second set of resources, wherein the direct relationships of the second set of pedigree fragments refer to the second set of resources as objects within the statements; and a pedigree assembly module executing on the processor to assemble 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. - View Dependent Claims (10, 11, 12, 13, 14, 15)
