Abstract: Methods and systems for data management are disclosed. With embodiments of the present disclosure, data files originating from the same source data can be de-duplicated. One such method comprises calculating one or more of a first characteristic value for first data in a first format, and one or more second characteristic values for one or more data in one or more second formats into which the first data can be converted, said characteristic value uniquely representing an arrangement characteristic of at least part of bits of data in a particular format. The method also includes storing one of the first data and the second data in response to one of the calculated characteristic values being the same as a stored characteristic value corresponding to a second data.

Abstract: Instance documents related to policy enforcement are gathered according to a business requirement. The instance documents are instantiated from corresponding schema documents. An instantiated context model, including references to the gathered instance documents, is generated from a context model definition. A policy set to be enforced using the instantiated context model is generated according to the gathered instance documents. An enforcement sequence of policies in the policy set is determined. The policies are applied to the instantiated context model according to the enforcement sequence.

Abstract: According to various embodiments, a method and apparatus for providing a virtual appliance are described. The method includes: obtaining metadata of a specific virtual appliance based on a received request for obtaining the specific virtual appliance, the metadata describing information about virtual machines involved in the specific virtual appliance, determining an association relationship between the specific virtual appliance and at least one other virtual appliance according to the metadata, and providing resource information for obtaining the specific virtual appliance according to the association relationship, the resource information including a plurality of resource addresses, at least one of the plurality of resource addresses pointing to a storage location of the at least one other virtual appliance.

Abstract: A method, apparatus, and/or computer program product creates a virtual resource package. Metadata related to a machine is captured, where the machine is a physical machine and/or a virtual machine. A constraint definition describing a configuration constraint of the machine is generated based on the captured metadata. A disk image file of the at least one machine, the captured metadata and the generated constraint definition are packaged to generate the virtual resource package.

Abstract: A method for enforcing context model based Service-Oriented Architecture (SOA) policies is provided, which includes: gathering instance documents related to policy enforcement according to a business requirement; generating an instantiated context model using the gathered instance documents; generating a policy set to be enforced according to the gathered instance documents; determining an enforcement sequence of policies in the policy set; and applying the policies to the instantiated context model according to the enforcement sequence. The method for enforcing context model based SOA policies may flexibly gather the instance documents according to scenarios and purposes of the policy enforcement to define the policy scope, such as project, application, service, etc., and may be applied to various types of the SOA policies. In addition, a policy engine for enforcing context model based SOA policies is provided.

Abstract: Embodiments relate to methods, systems, and computer program products for handling open authentication (OAuth) of an invoked web service in a process. An aspect includes determining whether an OAuth access token has expired. Another aspect includes initiating an automatic update of the OAuth access token based on determining that the OAuth access token has expired.

Abstract: A solution for generating a Service-Oriented Architecture (SOA) policy based on a context model is provided, which generates an application scope of the SOA policy; generates a context model; generates an action list for the context model based on action semantic modules customized by a user; generates a condition part of the SOA policy according to the context module; generates an action part of the SOA policy according to the action list; and combines the condition part and the action part to generate the SOA policy.

Abstract: Business application logic corresponding to a business is generated according to requirements of the business. The business application logic includes Web services and Widgets. The Widgets in the business application logic are mashed up to create a Widget mashup application. An adaptation relationship is established between the Web services and the Widgets in the Widget mashup application. An executable business process is generated for the business based on the business application logic and the adaptation relationship. An executable mashup Widget application is generated based on the Widget mashup application and the adaptation relationship.
