OS model |
“scheduler” elements contained inside OSModel element are converted into TaskScheduler elements in the following way: - OperatingSystem element is created and associated to the OSModel element
(Note: OperatingSystem class is newly introduced in 1.1.0)
- All the Scheduler elements present inside the OSModel element are moved to the OperatingSystem element as TaskScheduler’s
- All the places where Scheduler elements were referred earlier, are updated so as to refer corresponding TaskScheduler element
|
| read, write |
LabelAccessStatistic |
Software model |
“read” elements contained inside LabelAccessStatistic element are removed and “write” elements are replaced by tag name “value” based on the following criteria : - If the LabelAccess element containing LabelAccessStatistic ->contains the access as “write”, then all the “read” elements of LabelAccessStatistic are removed
“write” elements contained inside LabelAccessStatistic element are removed and “read” elements are replaced by tag name “value” based on the following criteria : - If the LabelAccess element containing LabelAccessStatistic ->contains the access as “read”, then all the “write” elements of LabelAccessStatistic are removed

Mapping model |
Based on the content of the “executableAllocation”, accordingly either “processAllocation” or “runnableAllocation” elements are created and the corresponding data of “exeuctableAllocation” is mapped. Below are the criterions : - If “executableAllocation” consists of Task element and Scheduler mapping then - > “ProcessAllocation” of type “mapping:TaskAllocation” is created
- If “executableAllocation” consists of ISR element and Scheduler mapping then - > “ProcessAllocation” of type “mapping:ISRAllocation” is created, and to it corresponding ISR element and “InterruptController” element are associated (
Note:If there is a mapping to “ISR” and “Scheduler” in “executableAllocation”, InterruptController element is created and referred in the “executableAllocation”. In this case previous mapping to the Scheduler element is lost)
- If “executableAllocation” consists of Runnable element and Scheduler mapping then - > “RunnableAllocation” of type “mapping:RunnableAllocation” is created

ITEA 1.1.0 Class’s removed in ITEA 1.1.1, details how data of these class’s is migrated :
-
LabelSwitchEntry
(present in Software model)
- Class is removed in ITEA 1.1.1, and as replacement following Class is introduced: "ModeSwitchEntry"
-
LabelSwitch
(present in Software model)
- Class is removed in ITEA 1.1.1, and as replacement following Class’s are introduced: "ModeSwitch, ModeLabel"
-
LabelValueEntry
(present in Stimuli model)
- Class is removed in ITEA 1.1.1, and as replacement following Class is introduced: "ModeValueListEntry"
-
Model migration behavior:
-
LabelSwitch
:
- From the referred “Label” element inside “LabelSwitch”, “ModeLabel” element is created with the same name -> and associated to the same Software Model where “Label” element is defined
- “LabelSwitch” element is replaced with “ModeSwitch” element, and it refers to the “ModelLabel” (created in the above step)
-
LabelSwitchEntry
:
- For all the LabelSwitchEntry objects inside a specific AMALTHEA model file, a single “Mode” element is created ( with the following naming convention : “mode_sw_<counter>_migration_generated” )
- Based on the unique values of LabelSwitchEntry elements, ModeLiteral objects are created
- LabelSwitchEntry is replaced by ModeSwitchEntry, based on the earlier “value” specified for LabelSwitchEntry -> corresponding ModeLiteral element is referred
- For details refer to the below figure:
-
LabelValueEntry
:
- For Label referred inside each LabelValueEntry, corresponding ModeLabel object is created in the software model and it is associated to the entry object.
- For all the LabelValueEntry objects inside a specific AMALTHEA model file, a single “Mode” element is created ( with the following naming convention : “mode_stimuli_<counter>_migration_generated” )
- Based on the unique values of LabelValueEntry elements, ModeLiteral objects are created
- LabelValueEntry is replaced by ModeValueListEntry, based on the “value” specified for LabelValueEntry -> corresponding ModeLiteral element is referred instead of “value”
!! For LabelValueEntry migration to be successful, it is mandatory to have SW-Model in the same model file. In case SW-Model is not present, migration of LabelValueEntry objects will not be performed.
- For details refer to the below figure:
Version ITEA 1.1.1 to App4MC 0.7.0
Below are the changes in the meta model from ITEA 1.1.1 version to APP4MC 0.7.0
- Instead of multiple namespaces (e.g. sw, hw, constraints, components, etc.) a single namespace “am” is introduced
-
Impact on 0.7.0 model file due to this change:
- xmlns:am="http://app4mc.eclipse.org/amalthea/0.7.0 is included in the xmi file, instead of other namespaces (e.g. xmlns:hw, xmlns:sw etc.,)
- xsi:type attributes will consists of namespace prefix as “am” in the value. Example:
<ports xsi:type="am:ComplexPort" name="Mem_1_port" bitWidth="16" direction="R" writeCycles="10" readCycles="10"/>
- Root tag will have “am” as the prefix. Example:
<am:HWModel xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:am="http://app4mc.eclipse.org/amalthea/0.7.0"/>
- Reference pattern is changed.
As there is single model namespace in 0.7.0, namespace prefix is removed before the class name (eg: “ABSMode?type=Label”).
- old:
<Element Name>?type=<NameSpace prefix>.<ElementClassName>
- new:
<Element Name>?type=<ElementClassName>
- Root tag of the model, changed from
AMALTHEA to
Amalthea
-
IPort interface is changed to abstract class
Port
- FInterface reference (i.e. Franca Interface) is removed from class FInterfacePort
-
Impact on 0.7.0 model file due to this change:
- If AMALTHEA models from previous versions have the reference to Franca Interface ports, as a part of migration this reference is removed. (
In this case, reference to the Franca Interface element is stored as a CustomProperty of type String inside FInterfacePort element)
- InterfaceKind ENUM literal values are changed from PROVIDES, REQUIRES to provides, requires
- Following class names are changed
|

- Below references are removed inside ComplexNode and HardwareTypeDescription (
both these class’s are part of Hardware Model)
- AbstractType[] attribute , AbstractType[] features
-
Impact on 0.7.0 model file due to this change: Content inside the attribute and features is stored as a CustomProperty elements inside the corresponding elements.
- Content of “AbstractType[] attribute” is stored in the CustomProperty, with key as “attribute#<attribute name>” and value as <attribute value>
- Content of “AbstractType[] features” is stored in the CustomProperty, with key as “feature#<feature name>” and value as <feature value>
- Below figure shows the changes between 1.1.1 model (
containing attributes & features) and the corresponding 0.7.0 model (
created using model migration utility)
- ProcessAllocation class removed from MappingModel, instead ISRAllocation (
maps ISR and InterruptController) and TaskAllocation (
maps Task and Scheduler)
-
Impact on 0.7.0 model file due to this change:
- processAllocation tag is removed from mappingModel, and instead of this taskAllocation and isrAllocation tags will be generated accordingly.
For details refer to the image

Root Tag in AMALTHEA model amxmi file: It is recommended to have “Amalthea” as a root tag in amxmi file.
Based on the above statement, if the AMALTHEA model file is having sub-model tag as root element (e.g. SWModel or HWModel etc.,), as a part of model migration -> root element is changed as “Amalthea” tag and the content of sub-model is copied inside it.
Input model (containing SWModel as the root tag):
"<am:SWModel xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:am="http://app4mc.eclipse.org/amalthea/0.7.0">
