Abstract
Abstract A method for executing searches for resources that span more than one private resource repository in a restricted-access resource sharing system is disclosed. The system includes at least one server node and multiple peer nodes connected to a network. Resources, such as data digital images, may be retrieved from the nodes based by issuing queries containing terms matching the metadata associated with the resources. The method includes maintaining storage of resources and associated metadata on respective peer nodes, wherein the associated metadata is based on at least one metadata vocabulary. Each of the peer nodes is allowed to indicate to the server that the metadata vocabularies associated with the resources are designated as private, thereby becoming a restricted access peer node. If a first restricted access peer node specifies to the server which metadata vocabularies the first restricted access peer node supports, a first level of privacy is provided whereby search queries received by the server that use the specified metadata vocabularies are passed to the first respective restricted access peer nodes for processing, while searches that do not use the specified vocabularies are processed by the server. If the first restricted access peer node does not specify to the server which metadata vocabularies the first restricted access peer node supports, a second level of privacy is provided whereby search queries received by the server are passed to the first respective restricted access peer nodes for processing.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
235 words
A method for executing searches for resources that span more than one private resource repository in a restricted-access resource sharing system comprising at least one server and multiple peer nodes connected to a network, the resource sharing network for storing resources, including data digital images, and for retrieving the resources based on metadata associated with the resources, the method comprising the steps of: (a) maintaining storage of resources and associated metadata on respective peer nodes, wherein the associated metadata is based on at least one metadata vocabulary; (b) allowing each of the peer nodes to indicate to the server that the metadata vocabularies associated with the resources are designated as private, thereby becoming a restricted access peer node; (c) if a first restricted access peer node specifies to the server which metadata vocabularies the first restricted access peer node supports, providing a first level of privacy whereby search queries received by the server that use the specified metadata vocabularies are passed to the first respective restricted access peer nodes for processing, while searches that do not use the specified vocabularies are processed by the server; and (d) if the first restricted access peer node does not specify to the server which metadata vocabularies the first restricted access peer node supports, providing a second level of privacy whereby search queries received by the server are passed to the first respective restricted access peer nodes for processing.
Claim 2
Independent Claim
235 words
A method for executing searches for resources that span more than one private resource repository in a restricted-access resource sharing system comprising at least one server and multiple peer nodes connected to a network, the resource sharing network for storing resources, including data digital images, and for retrieving the resources based on metadata associated with the resources, the method comprising the steps of: (a) maintaining storage of resources and associated metadata on respective peer nodes, wherein the associated metadata is based on at least one metadata vocabulary; (b) allowing each of the peer nodes to indicate to the server that the metadata vocabularies associated with the resources are designated as private, thereby becoming a restricted access peer node; (c) if a first restricted access peer node specifies to the server which metadata vocabularies the first restricted access peer node supports, providing a first level of privacy whereby search queries received by the server that use the specified metadata vocabularies are passed to the first respective restricted access peer nodes for processing, while searches that do not use the specified vocabularies are processed by the server; and (d) if the first restricted access peer node does not specify to the server which metadata vocabularies the first restricted access peer node supports, providing a second level of privacy whereby search queries received by the server are passed to the first respective restricted access peer nodes for processing.
Claim 3
Dependent Claim
35 words
The method of claim 1 further including the step of: routing responses generated by the first restricted access peer node in response to a particular search query to a requesting peer node through the server.
Claim 4
Dependent Claim
38 words
The method of claim 1 further including the step of: routing responses generated by the first restricted access peer node in response to a particular search query directly to a requesting peer node without going through the server.
Claim 5
Dependent Claim
97 words
The method of claim 3 wherein step (c) further includes the steps of: (i) embedding the search query in a locator for the first restricted access peer node; (ii) sending the locator to requesting peer node; (iii) using the locator to send the query to the first restricted access peer node; (iv) in response to receiving the query on the first restricted access peer node, searching the stored metadata on the first restricted access peer node for a match; and (v) returning resource locators for resources having metadata that match the query to the requesting peer node.
Claim 6
Dependent Claim
