 If a systems modeling tool conforms to the XMI specification and includes the XMI representation of the UML Profile for SysML and the XMI representations of Model Libraries defined by SysML, the tool provides the import and export of both SysML diagrams and model data from one tool to another. XMI (XML Metadata Interchange) is a format specification that enables the interchange of objects and models through an XML formatted file. It is based on a metamodel that defines the abstract syntax and semantics of the model elements. By conforming to the XMI specification, a tool can serialize and deserialize SysML models in terms of XML elements and attributes. The tool can also include the XMI representation of the UML Profile for SysML, which defines the mapping of SysML concepts to UML concepts, and the XMI representations of Model Libraries defined by SysML, which provide predefined types and units for SysML models. This way, the tool can import and export both SysML diagrams and model data from one tool to another, ensuring consistency and interoperability.

The best practice to model a software application in a SysML model for a system is to use a block stereotyped with «software» to represent the software application and its interfaces. A block is a modular unit that encapsulates its structure and behavior and can be connected to other blocks via ports and connectors. A stereotype is an extension of an existing metaclass that adds additional information or semantics to a model element. By using a block stereotypedwith «software», the software application can be modeled as a system component with its own properties, operations, ports, flows, etc., and can be allocated to hardware blocks or other software blocks.

 Interaction-based exchange is a data exchange mechanism that uses an application programming interface (API) to access data in one tool and make it available in another tool. The API allows for direct communication and synchronization between the tools without requiring intermediate files or repositories. This approach can provide better performance and consistency than file-based or repository-based exchange.

 XMI is a standard format for exchanging metadata information via XML, such as UML models. XMI supports a mechanism for producing a special XMI file that contains only the differences between two versions of a model, called a difference model. This file can be imported into another tool to apply the changes to the original model. This approach is more efficient and reliable than exporting and importing the entire model or parts of it

The information in option E is necessary and sufficient for the engineering team to begin selecting and procuring COTS components for the embedded real-time control system. This information defines the timing and cost requirements and constraints for the system and its components, which are essential for evaluating and comparing the available COTS components. The other options are either incomplete or irrelevant for this purpose. For example, option A does not include the minimum period of time between critical inputs, the maximum number of critical inputs, or the cost information. Option B does not include the minimum period of time between critical inputs or the maximum number of critical inputs. Option C does not include the maximum number of critical inputs or the allocation of cost to system components. Option D does not include the maximum number of critical inputs.

To reuse the type definitions of the properties of a stereotype, the profile needs to import the package where these types are defined. An import relationship indicates that the elements in one package can be referenced by another package without a qualified name. By importing the package with the types, the profile can use them as attributes of the stereotype without having to redefine them.

The information that is required to define a viewpoint in SysML in addition to stakeholders is concerns, languages, methods, and purpose. Concerns are aspects of interest about a system that are addressed by a viewpoint. Languages are notations or modeling techniques used by a viewpoint to represent a view. Methods are processes or guidelines for constructing or interpreting views that conform to a viewpoint. Purpose is an explanation of why and how a viewpoint addresses stakeholder concerns.

Tagged values can be defined only as attributes of stereotypes. A tagged value is an extension of a model element with additional information that is not part of its standard properties. A tagged value is defined by an attribute of a stereotype that is applied to the model element. The attribute specifies the name and type of the tagged value.

Working in UPDM compliance level 1 allows users to bring SysML elements into the architecture to enhance the hand-off between Systems of Systems and Systems. Compliance level 1 is based on UML and SysML concepts and provides integration with system modeling using SysML. Users can use SysML elements, such as blocks, ports, connectors, parametrics, etc., to model system components and their interactions in more detail and precision than using UML elements alone. This can facilitate the transition from architecture modeling to system design and analysis.

Stereotypes should be grouped in profiles to facilitate re-use in later projects. A profile is a mechanism for extending UML or SysML with additional modeling elements that are not part of the standard language. A profile defines stereotypes, which are extensions of existing metaclasses. A profile can be applied to a model to make the stereotypes available for use. Bygrouping stereotypes in profiles, they can be easily reused in different models or projects.
