Web service is associated with a number of specifications. Management specification is one of the primary concerns in web service specifications. At Contempo technologies we make a point to see that web management specifications are up to your satisfactions. WS-management, WS-management catalog, WS-resource transfer and WSDM are the four specifications under management specifications. A crucial application for these services is in the area of systems management. To promote interoperability between management applications and managed resources, this specification identifies a core set of Web service specifications and usage requirements to expose a common set of operations that are central to all systems management.

WS-management
WS-management is an open standard defining SOAP based protocol for the management of servers, devices, applications and various web services. It is completely based on open standards and internet standards. WS-Management provides a common way for systems to access and exchange management information across the IT infrastructure.

SOAP
To implementation Web Services in computer networks SOAP is needed, it is a protocol specification for exchanging structured information. Simple object access protocol relies on Extensible Markup Language (XML) for its message format, and usually relies on other Application Layer protocols, most notably Remote Procedure Call (RPC) and Hypertext Transfer Protocol (HTTP), for message negotiation and transmission.

WS-management catalog
This specification defines the default metadata formats for the discovery part of WS-Management. The catalog is used to discover available management resources such as network adapters or disk drives. The intent is to allow services to publish information about available resources and have it discovered and processed automatically by a wide variety of tools, and to allow more or less automatic WS-Management bindings to be built. It is important to realize that the client accesses the resource catalog entry to discover how to build an address to a resource at the protocol level and how to discover what capabilities the resource has.

WS-resource transfer
This specification extends WS-Transfer operations, adding the capability to operate on fragments of management resource representations. A Web service that is addressable by an endpoint reference as defined in WS-Addressing and that can be represented by an XML document. This representation can be accessed using the operations defined in the WS-Transfer and WS-Resource Transfer specification. WS-Transfer defines operations to Get, Put, Create and Delete representations of resources. WS-Resource Transfer extends these operations to add the capability to operate on fragments of the resource representations.

WSDM
WSDM stands for web service distributed management for managing and monitoring the status of other services. Its goal is to allow a well-defined network protocol for controlling other service. Wsdm consists of two specifications such as MUWS and MOWS. MUWS defines how to represent and access the manageability interfaces of resources as Web services. MOWS define how to manage Web services as resources and how to describe and access that manageability using MUWS
