Generated from UML->XMI->intermediate->XSD. This class represents a web service that can be used to access SimDM/Resource-s registered in for example a SimDB. The precise way in which the web service gives access to these results not specified in detail. It includes simple downloads, and services implementing standards such as SimDAL. SimDM/Service is related to SimDM/Resource and can be used for more general purposes than simply giving access to results of a single experiment. It may be a web service that can handle results of any experiment performed by a particular SimDM/Protocol, or give access to all resources in a SimDM/Project. The main goal of introducing SimDM/Service in the model is so that users can find web services based on requests for specific tyes of simulations etc. For example users may wish to find web services giving access to hydro simulations of clusters of galaxies with particular properties. . It is assumed that web services registerd in a SimDB are also registered in a Registry which will store the more detailed capbilitieis and other service metadata. Therefore such details are not introduced here. _12_1_1_8e0028f_1178634214328_979805_732 The base URL of this SimDM/Service. In case the web service implements a standard IVOA protocol such as SimDAL, this base URL can be used in the same way as other typical IVOA S*AP services. Parameters defined by the standard may be added to the base URL so that a proper HTTP GET request can be created for accessing the web service directly. _12_1_1_8e0028f_1178636158875_594641_863 The IVO identifier by which this service is registered in an IVOA Resource Registry. Each SimDM/Service should be registered in such a registry and this identifier allows one to obtain the full description of this service as defined by the Registry standard. _12_1_8e0028f_1224855067250_956488_697 The AccessibleResource class represents an association between the containing SimDM/Service and the SimDM/Resource-s that are being made accessible by that service. _12_1_8e0028f_1224854880765_748997_568 Description of how the particular SimDM/Resource referenced by this object is made available by the parent SimDM/Service. _12_1_8e0028f_1240400082078_785740_1077 Direct URI for accessing the referenced SimDM/Resource using the parent service. The parent service has a baseURL through which one can access the service interface. From there one may be able to browse through all SimDM/Resource-s that are made available, but a specific (data access) protocol to reach a given SimDM/Resource or how to browse these SimDM/Resource-s is not defined by this model. IF it is possible to access the SimDM/Resource directly through the SimDM/Service, for example to download or browse its contents, this attribute gives the corresponding URI. _12_1_213004e4_1274452427640_607492_522 This reference points to the SimDM/Resource that this SimDM/AccessibleResource class associates to the SimDM/Service. The end point can be any SimDM/Resource. _12_1_8e0028f_1240400012437_227403_1070 Represents a SimDM/Service conforming to a SimDAL protocol. This is a place holder class that may in future version of the model be defined in more detail when SimDAL services themselves have been fully specified. _12_1_213004e4_1274450439218_262420_253 The CustomService class represents a custom SimDM/Service for accessing SimDM/Resource-s. It is not assumed that a predefined protocol is implemented. Its main role is to distinnguish it from SimDAL and other services implementing potential, future IVOA standards. But many interesting custom services giving access to simulation results exist and can be reistered and discovered through this class. _12_1_213004e4_1274450465156_344922_297
