cetis SWNI: Implementation & Testing By Scott Wilson, CETIS

cetis cetis Specifications Enterprise –1.0.1 –1.1 –CETIS UK FE Application Profiles LIP –1.0 –CETIS/CRA UK Progress File (Transcript & PDR)

cetis cetis Specifications (contd.) Metadata –IMS metadata –IEEE LOM 1.0 –CETIS/UKOLN Common metadata framework Content Packaging –IMS CP (1.1.3…)

cetis cetis Implementation using Web Services Transport (HTTP) Envelope (SOAP) –Header –Body –Attachments (MIME) Processing rules Endpoint Interfaces (WSDL)

cetis cetis Message Structure SOAP Envelope Header Body Attachment Processing information (routing, security, session, context, action) Payload data (plaintext Enterprise xml, zipped and/or encrypted, additional media etc) MIME Boundary

cetis cetis One-way Synchronization synchronous point-to-point communication MIS Application Agent VLE Application Agent SYNC HTTP Transport WSDL Interface Add Person Delete Person Update Person Add Group Qual_Aim_Enrol (etc)

cetis cetis Synchronize/Acknowledge (a)synchronous point-to-point communication MIS Application Agent VLE Application Agent SYNC HTTP Transport WSDL Interface Add Person Delete Person Update Person Add Group Qual_Aim_Enrol (etc) WSDL Interface Acknowledge Error ACK

cetis cetis Request and Response (a)synchronous point to point communication MIS Application Agent VLE Application Agent REQUEST HTTP Transport RESPONSE WSDL Interface Query WSDL Interface Results

cetis cetis Spaghetti Junction the logical consequence of point-to-point for large enterprises Application

cetis cetis Mediated Events (contd.) MIS Application Agent VLE Application Agent Message Oriented Middleware EVENT VLE Application Agent EVENT WSDL Interface Register Agent Provide ObjectType Subscribe to ObjectType Create Event

cetis cetis Supporting the models IMS: Enterprise Services with Web Services Binding –Request/Response –Synchronize/Acknowledge CETIS: Messaging Services for MLEs –Synchronize/Acknowledge –Mediated events

cetis cetis Testing Test profile –Identify supported services (if using WS) Which transactions supported Which message exchange pattern supported –Identify specific data model support for transactions Needs to be detailed, e.g: UK FE Application Profile v0.9r3 Profile #2 (QualAim_Enrol)

cetis cetis Testing: Data XML Schema Validation Vocabulary agreement and validation Additional data model validation not enforced by schema Functional validity testing (semantics) Methods: XML Spy, Schematron etc. for xml validation, but also manual inspection of data both in the raw and as part of a transaction

cetis cetis Testing: Web Services WSDL interface conformance to W3C SOAP envelope conformance to W3C SOAP Header schema validation against MLE messaging profile, where used Example transactions, including error cases Methods: XML Spy for validation…plus functional testing of delivered systems
