1 Introduction
1.1 Bulk Data Exchange Management Service Overview
The Bulk Data Exchange Management Service (BDEMS) specification is the definition of how systems manage the exchange of structured bulk information between learning information systems. The Bulk Data Exchange Management Service specification is constructed following the recommendations documented in the IMS GLC Abstract Framework (IAF) [IAF, 03a], [IAF, 03b], [IAF, 03c]. This means that this specification is based upon the concepts of:
· Interoperability – the Bulk Data Exchange Management Service focuses on the exchange of structured bulk data between learning information systems. There are no definitions in the specification on how the data is managed within the systems;
· Service-oriented – the Bulk Data Exchange Management Service defines the exchange of information in terms of the services being supplied by the collaboration of the systems;
· Component-based – for example, the Bulk Data Exchange Management Service is combined with the Person Management Service, Group Management Service, Membership Management Service, Course Management Service and Outcomes Management Service to provide the Learning Information Services [LIS, 11a];
· Layering – the Bulk Data Exchange Management Service is a part of the Application Services layer but it interacts with the services available in the Common Services layer e.g., authentication;
· Behaviors and Data Models – the Bulk Data Exchange Management Service is defined in terms of its behaviors and data models. The behaviors cause changes in the state of the data model and the state of the data model will only be altered as a result of a clearly defined behavior;
· Multiple Bindings – the Bulk Data Exchange Management Service information model is defined using the Unified Modeling Language (UML). This enables reliable mapping of the information model into a range of different bindings. The binding of immediate importance is to the Web Services Description Language (WSDL);
· Adoption – whenever appropriate, the Bulk Data Exchange Management Service specification makes use of other IMS GLC and non-IMS GLC standards and specifications.
The aim of this specification is to enable systems to exchange structured bulk data. The defined service can be included in any type of system e.g., Student Information System, Human Resources System, etc. A ‘bulk data’ object can be composed of many different types of structured objects e.g., ‘person’, ‘group’, ‘course offering’, etc. Six operations are supplied that allow a service to announce the presence of the bulk data file and to report the retrieval of the bulk data file. A separate Web Service file exchange protocol is defined to obtain the bulk data file.
1.2 Scope and Context
This document is the IMS GLC Bulk Data Exchange Management Service Information Model v1.0 and as such it is used as the basis for the development of the following document:
a) IMS GLC Bulk Data Exchange Management Service WSDL Binding v1.0 [BDEMS, 11] – the description of the WSDL binding of the Information Model.
The core uses-cases for the Bulk Data Exchange Management Service are described as a subset of the Learning Information Services Specification [LIS, 11a]. This is the first version of this service.
This information model defines Bulk Data Exchange Management Service Abstract Application Programming Interface (a-API). The Learning Information Services specification, of which the Bulk Data Exchange Management Service is a component, is a series of behavioral models that define how the data models are to be manipulated. These behavioral models are described using the Unified Modeling Language (UML) [SDN07, 07].

2 Bulk Data Exchange Management Service Description
2.1 An Abstract Representation
It is important to remember that this document contains the description of the underlying information model in terms of the abstract API. The manner in which this abstract representation is visualized is not intended to dictate the implementation form of a Bulk Data Exchange Management System. The breakdown of the service into its interface classes is a convenient way to document the set of behaviors. The objective for producing these interfaces is to identify and define the messages that are exchanged between the end-systems to realize the system behaviors required of the service.
The internal organization of an implementation of the full abstract API is beyond the scope of this specification. The only constraint is that the external behavior of the abstract API complies with this specification. This means that a .NET, J2EE, etc. physical implementation of this abstract API does not have to represent the functionality using the same breakdown of operations/methods. This physical implementation is not subject to the conformance specification.
It is important to note that the UML representation of the interfaces is used to help develop and document the Bulk Data Exchange Services Information Model. It is not a requirement for an implementation to implement this interface as defined i.e., to use the same parameters, etc. Conformance against this specification will be confirmed by inspecting the appropriate binding of the information model and ensuring that the relevant information is present and those different sequences of activity result in the predicted and mandated behavior. It is essential that the behaviors described by each of the operations are fully supported and it is also essential that the behaviors described by different sequences be also maintained.
2.2 Bulk Data Exchange Management Service Architecture & Specification Model
The basic architectural model for the Bulk Data Exchange Management Service specification is shown in Figure 2.1. In this architecture the scope of the IMS GLC Bulk Data Exchange Management Service specification is shown as the dotted line. The scope of the interoperability is the data and behavioral models of the objects being exchanged.
Figure 2.1 Bulk Data Exchange Management service architecture model.
It is important to remember that the structure of the exchanged information has NO bearing on how the same information is contained within the ‘source’ and ‘target’ Learning Information Services systems (the bulk data object repositories in the two end-systems). It is simply a representation of the data used to facilitate exchange between the end-systems. The only constraint on the end-system repositories is that they provide data persistent consistent with the required behavior.
2.3 Bulk Data File
The core of the BDEMS is that two systems exchange bulk data using external data files (the number of physical files exchanged is an implementation issue). The logical structure of the bulk data file is shown in Figure 2.2b and the equivalent physical distribution to data files is shown in Figure 2.2a. The bulk data file is acquired using the Web Service (alternative file transfer protocols are also possible but not addressed in this specification).
Figure 2.2 Composition of a bulk data file.
In Figure 2.2b, the top-level container for the bulk data file is the bulk data record that is composed of an unbounded number of Transaction Records. Each record is used to contain the operation for a particular service and interface combination. The order of the transaction records is significant however there is no explicit relationship between the transaction records.
2.4 Handling the Service Status Codes
Each operation in a service is mapped to an appropriate message exchange pattern. Any response/acknowledgement message will contain status information. This status information provides contextual information about the completed success or otherwise of the operation. There are two types of status information that are available to the end-systems:
· Business transaction – these are the status reports that reflect the business logic of the transactions being exchanged by the end-systems. This status information will be contained within the message header under a specially defined data structure. The status information contained herein is also used to contain any error codes i.e., error reporting is handled as a subset of status information reporting;
· Messaging fault – these are fault codes that are reported by the messaging infrastructure and which are carried in the messages.
It is important to note that messaging errors may indicate that the original request never reached the service provider end-system. In this case the service consumer implementation that handles the status information is responsible for mapping the message infrastructure failure codes to the equivalent business transaction status code. The message infrastructure failure codes have no meaning with respect to an IMS GLC specification. The IMS GLC specifications do not describe how the status information is to be handled within an end-system i.e., this will depend on how the abstract API is physically realized within an implementation. Therefore, it is important that an implementation can:
· Combine the transaction status information and any message fault error codes in a single integrated status reporting mechanism. Any other system failure information that is made available by an implementation should also use the same mechanism;
· Examine the status information reported after the completion of the appropriate phase of an operation and especially once the operation has been completed. This may require an explicit status information call or it may be reported as part of the API call;
· Differentiate the status information reports for each transaction within an operation. Remember that some specifications provide operations that can contain more than one transaction request and that a different status report may be given for each of those transactions.
Exception handling is the system’s response to known or unknown error conditions. Exception handling is outside the scope of an IMS GLC specification. However, an error condition should not cause the end-systems to fail in an uncontrolled manner. The requirement for every operation to return status information is to enable an implementation to terminate in a controlled fashion.
3 Behavioral Model
3.1 Service Definition
The BulkDataExchangeManagementService is used to model the service responsible for manipulating information used between Learning Information Services systems. The BulkDataExchangeManagementService interface is shown in Figure 3.1.
Figure 3.1 BulkDataExchangeManagementService interface definition.
The BulkDataExchangeManagementService has a single interface: BulkDataExchangeManager that supports the manipulation of a single bulk object.
NOTE: The operation used to download the data file(s) is not defined in Figure 3.1. Instead, the specific Web Service binding is defined in Section 6.
3.2 BulkDataExchangeManager Interface Description
The BulkDataExchangeManager interface class describes the operations that are permitted on ‘bulk data’ objects. The interface stereotype indicates that there are no attributes for this class. The set of operations are summarized in Table 3.1.

3.2.1 AnnounceBulkDataExchange() Operation
|
Name: |
announceBulkDataExchange |
|
Return Function Parameter: |
StatusInfo – the status of the announce request. The permitted status codes are defined in Tables 3.2 and A.2. |
|
Supplied (in) Parameters: |
transactionId:NormalizedString – the unique identifier assigned to this transaction by the service provider. bulkBlockManifest:BulkBlockManifest – ‘house-keeping’ information about the bulk data files that are available including the URLs. |
|
Returned (out) Parameters: |
servicesSupported:ServicesSupported – a report of the services supported by the consumer responding to this announcement. |
|
Behavior: |
When the service provider issues the ‘announceBulkDataExchange’ request the target must acknowledge the receipt of the announcement (this must be acknowledged to ensure that the service provider does not enter a retransmission mode, etc.). This is the first phase of the asynchronous service and all responses must return the transactionId supplied in this operation. The service consumer will then use an appropriate file retrieval protocol to obtain the file identified by the URL(s) given in the request message. The ‘house-keeping’ information is used to ascertain whether or not the consumer can make use of the information in the file. Once this call has been issued, the service provider will stop real-time event notifications. This will be restarted once the bulk exchange has either been completed or prematurely terminated. A service consumer receiving this announcement will provide, in the response, a description of the services and operations supported. |
|
Notes: |
None. |

3.3 Service Choreography
The Bulk Data Exchange Management Services is an asynchronous service. There are two basic patterns:
· Service provider driven announcements;
· Service consumer driven requests.
Figure 3.2 is a schematic representation of the service choreography for the service provider driven process; the announce/report service calls choreography.
Figure 3.2 Service Provider driven asynchronous service choreography.
The two phases of the BDEMS are separated by the data file download protocol (using a secure HTTP message file retrieval i.e., HTTPSget). The first phase is established when the ‘announceBulkDataExchange’ request message is issued by the service provider. Once received by the service consumer the announcement acknowledgement is sent back to the service provider. At some later time, determined by the service consumer, the identified set of data files are retrieved using one or more ‘HTTPSget’ calls (the data files may, or may not, be stored on the service provider or some other data store); see Section 6. The contents of the data files are inspected. Once the data files have been processed, the service consumer issues the ‘reportBulkDataExchange’ message to the service provider. In response the service provider acknowledges receipt of the report message. Real-time event notifications and processing between these two systems is suspended during this choreography.
Each of the ‘announceBulkDataExchange’ and ‘reportBulkDataExchange’ request/acknowledgement message sequences is synchronous i.e., the service is blocked until the corresponding acknowledgement is received. It is the choreography between the two sets of message sequences, and the download protocol, that is asynchronous.
The service consumer driven choreography is shown schematically in Figure 3.3. The service consumer issues the ‘requestBulkDataExchange’ call. At some point later, the service provider issues an ‘announceBulkDataExchange’ request to inform the service consumer of the location of the requested data files. The choreography now follows the sequence as shown in Figure 3.2.
Figure 3.3 Service Provider driven asynchronous service choreography.
In Figures 3.2 and 3.3 the acknowledgement messages are empty messages but are tagged so that the original request message is identified. An appropriate status code is returned i.e., the acknowledgement may indicate that the request will not be completed.
The choreographies displayed in Figure 3.2 and 3.3 address the success sequence of events. Alternative choreographies are possible when failure conditions are detected or the service consumer wishes to prematurely end the process i.e., and return to real-time event processing. These alternate choreographies are supported by the following operations:
· In Figure 3.2 the service consumer can restart the real-time event processing without downloading the bulk data file(s) by issuing the ‘ignoreBulkDataExchange’. Real-time event processing restarts once the service provider acknowledges receipt of the ‘ignoreBulkDataExchange’;
· In Figure 3.3 the service provider may issue the ‘announceFailureBulkDataExchange’ instead of the ‘announceBulkDataExchange’. This occurs when the service provider is unable to service the original request. For example, the service provider may be unable to apply the required data retrieval filters;
· In Figure 3.3 the service consumer may prematurely cancel the bulk data exchange by issuing the ‘cancelBulkDataExchange’ operation. At this point the service provider will cancel the generation and storage of the corresponding bulk data files. Real-time event processing is immediately restarted by both the service consumer and provider.

At initialization the value is set to ‘1000-01-01T00:00:00.000’. The value is changed to the current time for every operation that results in a change of the value of the data stored in the ‘group’ object.
All values are to be rounded down at the level of greatest resolution.

4.7 StatusInfo Class Description
This is the container for the status information returned by the target to the source. The structure of this class is described in the IMS/GLC General Web Services specification v1.0 (Appendix A) [GWS, 05].
5 Bulk Data File Data Model
The bulk data model defines the logical structure of the data to be stored in the external data file(s) that is exchanged between BDEMS systems. All UML diagrams expressed as “Platform Independent Model” are non-normative. Normative tables defining the classes in this Information Model follow the informative UML diagrams. A full definition of the UML Profile and the terms used in the normative tabular descriptions in this document to describe the PIM can be found in [SDN07, 06].
In the tables in this section the character sequence “n/a” is used to mark a field “not applicable.” Any field so marked is not relevant to the class being defined. Features so marked shall be ignored when binding a class defined by this Information Model.
5.1 Key terms and concepts
Classes in this information model are classified into three abstract class types. These abstractions are bound to specific data structures for machine processing in the IMS GLC Bulk Data Exchange Management Services v1.0 WSDL Binding Version 1.0 [BDEMS, 11]. The three abstract class types are:
· container: A container class may be a parent of one or more child classes;
· value: A value class shall not be a parent. That is, it shall not be a composite of characteristic, container, value, or unspecified class types. A value class shall always be a child of a container class and shall have semantic value within the scope of its parent class’s semantic value;
· unspecified: An unspecified class may be a parent. An unspecified class serves as an extension point for this Information Model.
Table 5.1 lists the class descriptors used to describe the abstract classes and definitions of the descriptors.
|
Descriptor |
Definition |
|
Class name |
The name given to the class being described. |
|
Class type |
The abstract class type of this class. |
|
Data type |
For value and characteristic classes, the allowed structure for valid values for the class. Valid data types are: Boolean: The primitive, two-valued data type that uses the keywords “true” and “false” to indicate the logical state of an object. DateTime: The DateTime represents a combined date and time in the format of ISO 8601 i.e., ‘YYYY-MM-DDThh:mm:ssTZD’. The time is denoted in Coordinated Universal Time (UTC) with TZD denoting the time zone offset in hours and minutes with respect to UTC. GUID: An identifier that is globally unique. This will be based upon the NormalizedString data-type that has a constrained value-space. Hexadecimal: A hexadecimal number. Integer: An integer. LUID: An identifier that is locally unique i.e., within the context of the two communicating systems. This will be based upon the NormalizedString data-type that has a constrained value-space. NormalizedString: A sequence of printable characters that does not contain carriage returns or tabs. String: A sequence of printable characters. Unspecified: The data type is not known or is not important. URL: A string that conforms to the constraints of a URL. A normalized string for the of [1-4095 characters]. |
|
Value space |
The range of valid values for this class. If the value space is unspecified, it is not known or is not important. |
|
Multiplicity |
A property of a class indicating the number of times it may be used or appear in a given parent context. The values of this property are expressed as a range or shorthand for a range using this notation:
Multiplicities may also appear in short-hand notation in the UML models. The short-hand equivalents shall be (exclusive of bracketed comments):
Where multiplicity is greater than one, the importance of the ordering of siblings is also indicated by appending either “,”ordered or “,” unordered. Ordered specifies a sequence of siblings as listed, unordered specifies a collection or bag of siblings in which order is not important. |
|
Parents |
Lists classes that may be parents of this class. |
|
Children |
Lists the possible child classes of this class in the form “[” child *“,” child “]”. One or more child classes may be expressed within square brackets. Each child class shall be separated by a comma. Where more than one child is listed, the importance of the ordering of siblings is also indicated by appending either “,”ordered or “,” unordered. Ordered specifies a sequence of siblings as listed, unordered specifies a collection or bag of siblings in which order is not important. |

Description |
Contains descriptions relating to the class and its values space. |
In general, this specification does not define the ways in which an end system must be realized. However, the required interoperability behavior requires that an end system have certain characteristics. The static properties of these characteristics are defined in this Section, including:
· When an attribute has a multiplicity of ‘1..1’ then an end system must support only one instance;
· When an attribute has a multiplicity of ‘1..*’ then an end system must be capable of supporting at least one instance. The specification will also define the smallest permitted maximum number of instances that must also be supported by the end system;
· When an attribute has a multiplicity of ‘0..1’ then an end system must support a single instance;
· When an attribute has a multiplicity of ‘0..*’ then the specification will define the smallest permitted maximum number of instances that must also be supported by the end system.
When the object is passed as part of a service call then attributes that have a ‘1..1’ or ‘1..*’ multiplicity may not be exchanged. This is because the specification of an end system defines capability; an operational system may or may not exchange the associated information.

6 File Retrieval Approaches
6.1 HTTPS Get
Every implementation of the LIS BDEMS must provide the use of HTTPSget calls to access the data files that are created by a service provider. The call contains the URL provided by the bulk data manifest object in the corresponding ‘anounceBulkDataExchange’ message from the service provider (note that several URLs may be supplied and so several HTTPSget calls may be made by the service consumer).
Hypertext Transfer Protocol Secure (HTTPS) is a combination of the Hypertext Transfer Protocol with the SSL/TLS protocol to provide encryption and secure identification of the server. As default, it uses port 443.
The internal logical content structure of the file is as shown in Figure 5.1. The physical format follows the corresponding binding. The parameter ‘transactionId’ may be supplied depending on the implementation requirements.
6.2 Other Protocols
Apart from the file download approach mandated i.e., HTTPSget calls, the bulk data files may be obtained using any protocol that has been agreed (out-of-band) by the two systems.
6.2.1 File Transfer Protocol over SSL (FTPS)
File Transfer Protocol over Secure Sockets Layer (FTPS), commonly referred to as FTP/SSL, is a name used to encompass a number of ways in which FTP software can perform secure file transfers. Each way involves the use of a SSL/TLS layer below the standard FTP protocol to encrypt the control and/or data channels. This is NOT the same as either SSH File Transfer Protocol (SFTP), or FTP over SSH.
AUTH TLS, Explicit FTPS or FTPES, named for the command issued to indicate that TLS security should be used. This is the preferred method according to RFC 4217. The client connects using clear text on port 21 and may negotiate a secure TLS connection during the FTP setup or at any time thereafter. The server may allow non-encrypted FTP should negotiation fail. If the control channel is unencrypted, any subsequent data channels must also be unencrypted; if the control channel is encrypted, the subsequent data channels may be in clear or encrypted (this is a requirement of the AUTH mechanism defined under RFC 2228). If the command channel is not encrypted, the protocol is said to be using a clear command channel. If the data channel is not encrypted, the protocol is said to be using a clear data channel. Encrypted data channels and encryption on the control channel can be set up and torn down by the client at any time.
7 Extending and Profiling the Service
7.1 Proprietary Extensions
Proprietary extensions of the service are based upon two approaches:
a) The extension of the data models being manipulated by the current set of operations;
b) The inclusion of new operations to support new proprietary functionality.
It is NOT permitted to change the behavior of the current set of operations. Such changes MUST be supported by the creation of new operations.
7.1.1 Proprietary Operations
The definition of new operations should follow the same format as adopted herein. The new operations should be defined using a new interface type. Every operation must result in the return of a status code that describes the final state of the request on the target end system.
An example of creating such an extension is given in the accompanying Best Practices document [LIS, 11b].
7.1.2 Proprietary Data Elements
Extensions to the data model are only permitted where the IMSExtension class is available i.e., within the data models for the objects contained in the data file (see the corresponding Information Models for how to extend a specific data model of Person, Group, Membership, Course and Outcomes). It is not possible to extend the other parts of the data file or the service parameters.
7.2 Profiling the Service
This Service can be profiled. In general, Profiling is used to:
a) Refine which Interfaces are used and which operations are supported for each Interface;
b) Refine the data models (see the IMS GLC Application Profiling guidelines for more details on how data models can be profiled [APG, 05a][APG, 05b]).
Valid Profiles must be restrictive i.e., optional features can be removed or constraints increased but new features must not be added. A Profile of this service is made by annotating the UML supplied with the documentation for the specification.
Appendix A Service Status Codes
The summary list of status codes that can be returned by the different operations through the StatusInfo object is given in Table A1.1. The key to the entries is: ‘Y’ denotes the code may be returned by that operation. A blank entry means that the code cannot be returned by that operation.

There is a set of status codes that must be supported by each of the Bulk Data Exchange Management Service operations. These codes are described in Table A1.2.
Table A1.2 Common status codes for the service operations.
|
Status Code |
Explanation of the Cause of the Code |
|
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=unauthorizedrequest’ |
The source system is not authorized to make this request of the target. The reason for the refusal can be one of several causes. |
|
‘CodeMajor=Failure’
‘Severity=Status’ |
The target end-system received the request but is busy and cannot process the request. The request should be resubmitted. |
|
‘CodeMajor=Failure’ ‘Severity=Error’ ‘CodeMinor=linkfailure’ |
There has been a failure in the end-to-end system communications mechanism and so the request has not been delivered. |
|
‘CodeMajor=unsupportedLIS’ ‘Severity=Status’ ‘CodeMinor=*’ |
This service in LIS is not supported by the target system. Every system that implements any part of the LIS specification must return this status code for a service component in LIS that is not supported. |
|
‘CodeMajor=unsupportedLISoperation’ ‘Severity=Status’ ‘CodeMinor=*’ |
This operation is not supported by the target system. Every system that implements any part of the LIS specification must return this status code for an operation that is not supported in a provided service. |
Appendix B The Vocabularies
The vocabularies listed in the following Tables are the default set maintained under the IMS GLC Vocabulary Registry [SDN11, 06]. It is the responsibility of an implementation to ensure that it is using the correct and latest versions of the vocabulary files. Changes to the default vocabularies are permitted; this results in the creation of a new vocabulary that should be registered with IMS GLC. As part of a profiling process entirely new vocabularies may be defined to replace the default set.
