Detail report
In Swiss Learning Hub, a detailed report can be created per learning content if the report definition (report.xml) and certain SCORM keys (cmi.objectives.n.x and cmi.interactions.n.x are provided by the learning object.
Report definition
File name and location
The XML file must always have the file name report.xml and must be stored in the root of the respective SCORM package. The detail report can only be created if the Swiss Learning Hub can find and use this file.
Scheme
The XSD scheme can be used to create the report file.
Element report
Is the root element of the report XML
Element organization
This element refers to a chapter in the learning object.
Attribute:
id = unique ID of the chapter (e.g.: chapter_000_010_150)
name = Name of the chapter (e.g.: Schweizer Quiz)
No hierarchical chapter structures can be mapped. The chapters must be reduced to one level.
Example:
Chapter 1
Chapter 1-1
Chapter 1-2
Chapter 2
Chapter 2-1
report.xml
<organization name="Chapter 1">
    <item name="Page A" />
</organization>
<organization name="Chapter 1-1">
    <item name="Page B" />
</organization>
<organization name="Chapter 1-2">
    <item name="Page C" />
</organization>
<organization name="Chapter 2">
    <item name="Page D" />
</organization>
<organization name="Chapter 2-1">
    <item name="Page E" />
</organization>
Element item
This element refers to a learning object page within a chapter.
Attribute:
id = unique ID of the learning object page (e.g.: item_000_010_010_de)
name = Page title (z.B.: Testbeginn / Sprachen / Hauptstadt)
type = Type of learning object page (e.g.: dynamicFrames / multipleChoice / testInteraction, dynamicFrames)
Element question
This element refers to a question within a learning object (item).
Attribute:
name = Question text (e.g.: Zu welchem Kontinent gehört die Schweiz? Wählen Sie die korrekte Antwort.)
type = Question type (e.g.: multipleChoice / matchingDragAndDrop / matching / matrix)
maxScore = Maximum number of points for this question (for example: 1)
Element answer
This element refers to an answer option of a question.
Attribute:
id = unique ID of the answer choice (e.g.:  A / 1.A / usw.)
name = Description of the answer choice (e.g.: Afrika / Tennisspieler / Schweiz / Nicht Schweiz / usw.)
correct = Indicates whether the answer choice is correct or not (e.g.: true / false)
SCORM keys
The learning object must send data to the following SCORM keys according to SCORM 1.2 (Specification SCORM 1.2 RunTimeEnv).
cmi.objectives.n.id
cmi.objectives.n.score.raw
cmi.objectives.n.score.min
cmi.objectives.n.score.max
cmi.objectives.n.status
cmi.interactions.n.id
cmi.interactions.n.objectives.n.id
cmi.interactions.n.objectives.n.type
cmi.interactions.n.objectives.n.time
cmi.interactions.n.correct_responses.n.pattern
cmi.interactions.n.weighting
cmi.interactions.n.student_response
cmi.interactions.n.result
cmi.interactions.n.latency
Mapping SCORM keys and the report XML
The SCORM key cmi.interactions.n.id (value e.g.: item_000_010_020_en) can be used to determine which question is involved in the report XML. All further SCORM keys for this interaction can be read out using the index (n). The same logic is used for the SCORM keys cmi.objectives.n.x. The index (n) for cmi.objectives.n.x and cmi.interactions.n.x does not necessarily have to have the same value per learning object page, nor is the order of the indexes necessarily the same as the page order of the learning object.
Example (report.xml)
<item id="item_000_010_020_de" name="Geographie" type="multipleChoice">
    <question name="Zu welchem Kontinent gehört die Schweiz? Wählen Sie die korrekte Antwort." type="multipleChoice" maxScore="1">
        <answer id="A" name="Afrika" correct="false"/>
        <answer id="B" name="Amerika" correct="false"/>
        <answer id="C" name="Asien" correct="false"/>
        <answer id="D" name="Europa" correct="true"/>
    </question>
</item>
The SCORM key cmi.interactions.n.student_response (value e.g.: D) can be used to read out which response option the learner has selected.
Example (report.xml)
<question name="Zu welchem Kontinent gehört die Schweiz? Wählen Sie die korrekte Antwort." type="multipleChoice" maxScore="1">
    <answer id="A" name="Afrika" correct="false"/>
    <answer id="B" name="Amerika" correct="false"/>
    <answer id="C" name="Asien" correct="false"/>
    <answer id="D" name="Europa" correct="true"/>
</question>
The SCORM key cmi.objectives.n.score.raw (value e.g.: 1) can be used to determine how many points the learner has achieved in this question. The SCORM key cmi.interactions.n.result (value: correct / incorrect) shows whether the learner has solved the question completely correctly.

User Import
This document describes the file-based interface for user import into the Swiss Learning Hub. The personal data can be transferred in XML format via SFTP.
Data transfer
The files are transferred to the SLH server via SFTP. You will receive the SFTP access data from your SLH contact person.
File format
The file format is XML. The files must be encoded as UTF-8.
Process time
The process time can be determined individually (usually once a day at night), but must be coordinated with other processes by SLH.
User import
The full functionality of a user import can only be executed if all current users are listed in the transferred file. It is possible to configure the user import for a specific organizational unit only. Thus, further organizational units can be maintained manually in the Swiss Learning Hub and are not affected by further processes.
Processes
Removing users
The user import is designed to automatically remove users that are not listed in the file. The import can be configured accordingly, so that these users are effectively deleted (incl. all learning data) or archived (thus access by the user to the system is prevented, but as an administrator one still has access the user incl. all his/her learning data). If a user has set the value "Deletable" = no (0) in the Swiss Learning Hub, this user will never be removed by the user import. Thus, e.g. via the interface of the Swiss Learning Hub, external users can be subscribed, which do not have to be part of the user import file.
It's also possible to protect user from deletion by adding them to a specific organizational unit. In the setup a queryparameter ('excludeorgs') with a list of units which should be excluded from deleting/archiving.
Updating users
If a user is already integrated in the Swiss Learning Hub, it will not be newly created by the user import, but updated. However, the user must be uniquely identifiable for this purpose. In the first priority, the user is identified by the personnel number. A personal id can be, for example, a system ID from the conversion system or effectively an internal company value. It should be noted that this is unique and will certainly never be changed (e.g., in the event of a name change due to marriage) or reassigned to another person (e.g., e-mail addresses are reassigned after a resignation). This is important in case persons are not deleted from the Swiss Learning Hub for data protection reasons, but archived and certainly thus never overwritten by a new user. In second priority, the user is also identified by user name or e-mail address.
Updating user roles
By default the import does not update a users role. It's set on the first import (on create) of a user. After that, higher roles than “learner” have to be set manually in user administration. 
There is a functionality (query parameter 'changerole') in place which explicitly allows to update all user roles given in an import file.

Supervisor Import
Goal is to import/synchronize bigger sets of supervisor-to-users relations. 
Content-Type header defines the requested import format:
Supported content types:
application/json
application/xml
text/csv
Configuration Possibilities
Different importing-modes can be applied which define what will happen to entries that are available in the database, but are not available via the given import file anymore (deprecation).
None
In mode none - nothing will happen to the existing entries in our database if it's missing in the current file
Delete
Before the import we will remove all existing supervisor-user relations and recreate this from the provided file. This is the default setting
The other way round, if there are entries in the provided file that do not exist in our database, the entries are simply ignored, the import is not stopped and runs normally.
Supported content-types / hierarchy
JSON, XML and CSV are supportet filetypes. They all contain a simple list of supervisor<->user relation - the matching happens based on USERNAME.
A supervisor can have multiple users whereas a user only has one supervisor.
application/json
Example
[
  {
    "supervisor": "chefa",
    "user": "usera"
  },
  {
    "supervisor": "chefb",
    "user": ""
  }
]
application/xml
Example
<?xml version="1.0" encoding="utf-8"?>
<supervisors>
    <supervisor>
        <supervisor>chefa</supervisor>
        <user>usera</user>
    </supervisor>
    <supervisor>
        <supervisor>chefb</supervisor>
        <user/>
    </supervisor>
</supervisors>
text/csv

SSO / SAML 2.0

Integrations
Security Assertion Markup Language (SAML) is an open standard that allows identity providers (IdP) to pass authorization credentials to service providers (SP).
SAML transactions use Extensible Markup Language (XML) for standardized communications between the identity provider and service providers. SAML is the link between the authentication of a user’s identity and the authorization to use a service.
