2. 15 April 2003 Registry Workgroup Meeting University of Leicester Registry XML formatted queries processed for any registry services Technology: web services (soap), DB2 (database), XPath / XQuery (XML parsing) 4 service types (so far): data provider, data storage, data transformation, other registries Registry services perform query parsing and query processing Web Service Query: XPath Astrogrid Portal Registry Database: DB2 Data Archive Data Storage Data Transformation Distributed Network of Registries Job Control Data Mover Work Flow *** Registry use cases implemented through different SQL queries, not different service methods ***

3. 15 April 2003 Registry Workgroup Meeting University of Leicester AstroLog XML formatted messages to be queued or stored Technology: XMLBlaster (maybe???) Message Queue: queue job, user, and community messages Message Log (queue with database persistence): store job, user, and community messages Components send message to MQ: MQ delivers messages to destination component and AstroLog AstroLog: persistent message storage in a database Log Queue ASTRO MQ Interface

4. 15 April 2003 Registry Workgroup Meeting University of Leicester Use Cases: Registry 1.Look up community log: Receive request to look up community log from portal. Look up and return community log to portal. 2.Look up dataset provider: Receive request to look up datasets for the Workflow Controller. Look up and return metadata about dataset provider. 3.Store messages: Receive and store message from Job Controller. 4.Look up data locations: Receive request to look up data locations from Data Mover. Look up and return data locations to Data Mover. 5.Look up dataset details: Receive request to look up dataset details (such as UCDs) from Job Scheduler. Look up and return dataset details to Job Scheduler. 6.Receive queries: Query parser receives xml-formatted query from Portal. Convert XML query to SQL statement and execute SQL statement. 7.Build and send XML responses: Send SQL response to query response parser. Reformat SQL response as XML formatted response and send to Portal. 8.Registry database query: Execute SQL query on registry database.

5. 15 April 2003 Registry Workgroup Meeting University of Leicester Use Cases: AstroLog 1.Store messages: Store messages from the Job Controller, Dataset, or VOTable Catenation on the AstroLog. 2.Look up messages: Receive request from Portal to look up messages. Look up and return messages to the Portal.
