  18. TCIP 2.x Rob Ayers ARINC

  19. Discussion Topics • What TCIP 2.x contains • Incorporates TCIP 1 • Addition of Data Frames • Concept of Operations • Dialogs • XML

  20. Building the New Standard TCIP 2.X Dialogs Dialog Patterns Messages Data Frames New Frames TCIP 1 Msgs Data Elements New Elements TCIP 1 Elements

  21. New TCIP Standard • TCIP 3.0 • Plan to publish a new TCIP standard that incorporates the prior work, as well as XML Schema, and Dialogs • Single Standard instead of 9 documents

  22. TCIP 2.X Standard Outline • Overview • Definitions • Conformance • Understanding TCIP • Concept of Operations (For each Business Area) • Dialogs (Meaning of Patterns, Instantiations, Batch) • Dialog Patterns (Patterns are specified here)

  23. TCIP 2.X Standard Outline (continued) • Annex A-Data Elements(By Business Area) • Annex B-Data Frames (By Business Area) • Annex C-Messages (By Business Area) • Annex D-Dialogs (By Business Area) • Annex E-XML Schema • Annex F-Sample RFP Wording • Annex G-Traceability Matrix

  24. What is a Dialog? • A dialog specifies how and when a group of messages are used. • Dialogs are based on patterns. A pattern specifies a particular type of transaction which can then be used to implement many dialogs. • Patterns and Dialogs provide the context information necessary to effectively use TCIP messages.

  25. Pattern Example - Query Client Client Server Server AaaXxxSub AaaXxxSub Calculation Calculation AaaXxx CptSubErrorNotice Complete Complete Complete Complete Normal Execution of Query Error Response to Query

  26. Pattern Example-Periodic Client Server AaaXxxSub Calculation AaaXxx Timeout AaaXxx Timeout AaaXxx Timeout AaaXxx Subscription Expires Complete Complete Normal Execution

  27. Dialog Components • Name • Pattern • Business Area • Purpose • Narrative • Sequence Diagram • Assumptions • Notes • Message Identification

  28. eXtended Markup Language (XML) • TCIP I Standards are written in ASN.1 • TCIP 2.X uses XML as the implementation language, & include XML Schemas with the new Standards. • Advantages: Better known, more tools, more rapid supplier acceptance, take advantage of ubiquity of web-based products

  29. Data Element Example NameCPT-SubscriptionType Identifiercptdd 100 PurposeProvide the type of a requested subscription. The types allow the subscriber to ask for a one-shot provision of the information (query), a periodic update of the information, an update whenever the information changes (event), or cancellation of an existing subscription, or all existing subscriptions. Usage DefinitionENUMERATED { Query (1), Periodic (2), Event (3), Cancel (99), CancelAll (100), -- 4-98 reserved -- 101-255 reserved } (0..255)

  30. Data Element XML Schema XML-TAGCPT-SubscriptionType XML-SCHEMA <xsd:simpleType name="CPT-SubscriptionType" > <xsd:annotation> <xsd:appinfo> Query (1) Periodic (2) Event (3) Cancel (99) CancelAll (100) -- 4-98 reserved -- 101-255 reserved </xsd:appinfo> <xsd:documentation> </xsd:documentation> </xsd:annotation> <xsd:union> <xsd:simpleType> <xsd:restriction base="xsd:unsignedInt"> <xsd:minInclusive value="0"/> <xsd:maxInclusive value="255"/> </xsd:restriction> </xsd:simpleType> <xsd:simpleType> <xsd:restriction base="xsd:string"> <xs:enumeration value="Query"/> <xs:enumeration value="Periodic"/> <xs:enumeration value="Event"/> <xs:enumeration value="Cancel"/> <xs:enumeration value="CancelAll"/> </xsd:restriction> </xsd:simpleType > </xsd:union> </xsd:simpleType>

  31. Data Frame Example NameCptSubscriptionHeader Identifiercpt 1000 PurposeProvide a standardized header structure for subscription requests, cancellations, and responses. UsageThe expiration date and time must be specified. Report Interval is required if the requestedType is periodic, and not allowed otherwise. When the header is included in a subscription request, the information reflects the parameters desired by the subscriber. When the header is included in a response to a subscription request, the information reflects the parameters of the subscription actually provided. Subscriber and host identifiers are agency-assigned unique numbers to identify systems/applications. Request Identifier is a unique identifier that provided by the subscriber. The number is carried forward from the original request to all responses to the request by the server, and any cancellations must carry the same subscription number as the original request. DefinitionSEQUENCE { requestedType CPT-SubscriptionType, expirationDate CPT-DeactivationDate, expirationTime CPT-DeactivationTime, reportInterval CPT-TimeInterval OPTIONAL, requestIdentifier CPT-RequestIdentifier, subscriberIdentifier CPT-ApplicationID, hostIdentifier CPT-ApplicationID }

  32. Data Frame Example XML XML-TAGCptSubscriptionHeader XML-SCHEMA <xsd:complexType name="CptSubscriptionHeader" > <xsd:annotation> <xsd:documentation> </xsd:documentation> </xsd:annotation> <xsd:sequence> <xsd:element name="requestedType" type="CPT-SubscriptionType" > </xsd:element> <xsd:element name="expirationDate" type="CPT-DeactivationDate" > </xsd:element> <xsd:element name="expirationTime" type="CPT-DeactivationTime" > </xsd:element> <xsd:element name="reportInterval" type="CPT-TimeInterval"minOccurs="0"> </xsd:element> <xsd:element name="requestIdentifier" type="CPT-RequestIdentifier" > </xsd:element> <xsd:element name="subscriberIdentifier" type="CPT-ApplicationID" > </xsd:element> <xsd:element name="hostIdentifier" type="CPT-ApplicationID" > </xsd:element> </xsd:sequence> </xsd:complexType>

  33. Message Example NameCptStoppointListSub Identifiercpt 2001 PurposeRequest a specified version of stoppoint information UsageSubscription type should be query. If the information changes, then a new version number should be created by the scheduling system or schedule repository (server). The subscriber can become aware of such updates using the Subscribe Master Schedule Version dialog. The subscriber is able to determine the appropriate version of the stoppoints to request using the Subscribe Master Schedule Version dialog, thus the query does not need to be qualified with dates or other information. The include-details field indicates whether the response message should include additional details in the response message. These details provide optional information about a stoppoint (such as whether it is ADA-accessible). This detail is not required for all applications using the stop point list. An agency may decide to include all stoppoints for the agency within a stop point version, or to limit aversion to the stoppoints included on a route or group of routes, however all stoppoints referenced in a pattern list (SchPatternList message) must be included in the version of the stoppoints referenced by that pattern list. DefinitionSEQUENCE { subscriptionInfo CptSubscriptionHeader, stoppointVersion CPT-StoppointVersion, include-details CPT-Boolean }

  34. Message XML Schema XML-TAGCptStoppointListSub XML-SCHEMA<xsd:complexType name="CptStoppointListSub" > <xsd:annotation> <xsd:documentation> </xsd:documentation> </xsd:annotation> <xsd:sequence> <xsd:element name="subscriptionInfo" type="CptSubscriptionHeader" > </xsd:element> <xsd:element name="stoppointVersion" type="CPT-StoppointVersion" > </xsd:element> <xsd:element name="include-details" type="CPT-Boolean" > </xsd:element> </xsd:sequence> </xsd:complexType>

  35. Populated Message Example =================== ====XML Message =================== <SCH-MasterScheduleVersionSub> <subscriptionInfo> <requestedType>1</requestedType> <expirationDate>20091225</expirationDate> <expirationTime>0</expirationTime> <requestIdentifier>88</requestIdentifier> </subscriptionInfo> <beginDate>20020121</beginDate> <endDate>20020121</endDate> <routes> <SCH-RouteID>1</SCH-RouteID> <SCH-RouteID>5</SCH-RouteID> </routes> </SCH-MasterScheduleVersionSub>
