Abstract: A system and method for resource handling. In an environment for receiving a query and for providing a response, the query is used to search resources locally available. Metadata is associated with each of said resources. The resources and said metadata are both analyzed with respect to the query such that said response indicative of a match between at least two of said resources and said query is a ranked search result included in said response. The invention is exemplified in an adaptation to peer-to-peer network applications.

Abstract: A method and system for the transformation of extensible markup language (XML) documents. Specifically, one embodiment of the present invention discloses a method comprising modeling a source XML document corresponding to a source schema as a source tree having a plurality of source nodes, and modeling a target XML document corresponding to a target schema as a target tree having a plurality of target nodes. A sequence of transformation operations that transforms the source tree to the target tree is then generated.

Abstract: A method and system of valuing transformation between XML documents. Specifically, one embodiment of the present invention discloses a method for calculating a transformation cost for a transformation operation that transforms a source node in a source XML document to a target node in a target XML document. A data loss and potential data loss is measured for the transformation operation. Also, the operands in the transformation operation are scaled to measure their impact on the data loss and potential data loss. A transformation cost is calculated by considering the data loss, potential data loss, and scaling.

Abstract: A computer language for facilitating communication between web services, where web services may use disparate input and output document formats, and system using same. A Conversation Definition Language (CDL) is extended with transformational information to a Transformational Conversation Definition Language (TCDL). The CDL defines document types, transitions and interactions of a conversation between two or more web services. In a preferred embodiment, the transformational information is a subset of the interaction information. Stylesheets are used to define the semantics of the required transformation and the appropriate stylesheets are identified in the TCDL file. A conversation controller component reads the TCDL files that correspond to a given conversation and utilizes the transformation information, when necessary to transform documents between web services without human intervention.
