`ABSTRACT
`
`The subject matter disclosed herein provides methods and
`apparatus, including computer program products, for provid-
`ing a classification service. The method may receive a request
`to access a UDDIregistry. The classification service may
`access metadata representing a classification system for the
`data stored in the UDDIregistry. The classification service
`may provide the data stored in the UDDIregistryin a format
`based on the access metadata. Related apparatus, systems,
`methods, and articles are also described.

`Specification describes the web services, data structures, and
`the behavior of the UDDIregistry (see, e.g., OASIS UDDI
`Version 3.0.2 Specification, dated Oct. 19, 2004).

`For example, key identifiers may be used to identify informa-

`[0031] UDDI may be modeled using standard approaches,
`such as tModels. However, these standard tModels may be
`augmented to include one or more of the following: which
`services are available in a system (e.g., landscape); which
`services are modeled; which models are implemented in a
`system; which services are configured and thus invoked: and
`where should the service endpoints of the web service be
`exposed? To support such augmentation, additional classifi-
`cations and modeling may be implemented using UDDI
`tModels including descriptions for category group, refer-
`ences to identify a group, constituent category systems, and
`thelike.
