Abstract: A method and system for evaluating service definitions in a service-oriented architecture (SOA) system which provides service offerings categorized according to service categories using a taxonomy. A specification field receives a formal definition of a service. The formal definition is for inclusion to define one of service offerings of the SOA. A current grammar is determined which is currently in effect as a specification-requirement of acceptable definitions for a service category in which the service is categorized. The current grammar is a common grammar. The system determines whether the formal definition in the specification field is acceptable, by adhering to the current grammar determined to be currently in effect as the specification-requirement for the category of the service. The formal definition is accepted for the service when it is determined to be acceptable according to the current grammar. Otherwise, the formal definition is rejected.

Abstract: The invention concerns a method for generating at least one index (10) over XML documents (30) in an XML database (40); the method comprising the steps of: a. executing at least one indexing function (20) defined in the XQuery language; each indexing function (20) accepting an XML document (30) as input and returning at least one computed result; and b. storing each of the at least one computed results from the at least one indexing function (20) as a key (11) of the corresponding index (10) and a reference to the input XML document (30) as a value (12) of the index (10).
