MOBY-S Central Registry ("MOBY Central")
The MOBY Central registry allows registration of instances of
MOBY-compliant services, as well as the data-object classes, service
classes, and namespaces required by those services. A MOBY compliant
service (registered as having the service protocol "moby")is one that
uses only object/service classes defined in the MOBY Central registry,
presents its service interface via SOAP, and registers this service
interface in MOBY Central. In the coming months it will be expanded
to allow the registration of non-MOBY SOAP services, as well as CGI
services, but this will not affect the API described below for
MOBY-SOAP services.
The MOBY Registry is aware of both class and service-type ontologies,
and is able to expand its reporting of valid service providers through
the traversal of these ontologies.
MOBY Central Procedure Calls Overview
The following readonly procedure calls
must be
implemented by any instance of a MOBY Central registry:
findService |
Locate a service instance, matching various characteristics, such as
the provider name, the kind of input expected by the service, the kind
of output it provides, etc. |
retrieveService
|
Retrieve the definition for a service instance, as specified in
WSDL format. This information is used by the client to compose
queries. |
retrieveResourceURLs
|
Retrieve the URLs of all registered services. |
retrieveServiceProviders
|
Retrieve the names of all registered service providers. This
allows you to see what sites are providing MOBY services (in the
dozens). |
retrieveServiceNames
|
Retrieve the names of all registered services. |
retrieveServiceTypes
|
Retrieve the definitions and registration details of all registered service types. |
retrieveObjectNames
|
Retrieve the definitions and registration details of all registered object types.
|
retrieveObjectDefinition
|
Retrieve the class definition, in the form of the full registration details
for that class type. |
retrieveNamespaces
|
Retrieve a list of all registered namespaces |
retrieveObjectSchema
|
Retrieve an XML schema representation of a particular object class. This is currently not implemented since it appears to be impossible to represent MOBY Objects in XML Schema.
|
Relationships
|
Retrieve a list of MOBY object classes having a specified relationship with the
given class |
The following procedure calls
must be implemented by a
MOBY Central registry that also allows write access:
registerObjectClass
|
Register a new object class. This is useful if you want to add to
MOBY's object ontology, by creating a new data type. |
deregisterObjectClass
|
Deregister a deprecated object class. If your object is no longer useful, you can remove it from the ontology with this procedure. |
registerServiceType
|
Register a new service type. MOBY's service
ontology (we need a link) is pretty
small (most services are of type 'Retrieval'). If you need to expand
the ontology, this procedure does it. |
deregisterServiceType
|
Deregister a deprecated service type. |
registerNamespace
|
Register a new namespace. MOBY has a pretty large set
of namespacesneeds a link |
deregisterNamespace
|
Deregister a deprecated namespace term |
registerService
|
Register a new service instance. You have a new service you'd
like to share with the world. (There's a tutorial to show you how to
do it with Perl.) |
deregisterService
|
Deregister a service instance. This function is targeted for deprecation, but currently still works. |
The following procedure calls
may be implemented in a
MOBY Central registry:
DUMPneeds a link |
dump out the entire database |
registerServiceWSDL |
register a service based on an input WSDL
document |
