OCL stands for Object Constraint Language, which is a standard language for expressing constraints on UML and SysML models. Constraints are used to specify additional rules or conditions that are not directly captured by the modeling elements or their relationships. OCL can be used to define constraints on stereotypes, their properties, or their relationships in a profile. References:

A method is a technique or procedure for performing a specific task. A method is not generic and cannot be used out-of-the-box, because it depends on the context and purpose of the task. A method is not unnecessary to build an effective SysML model, because it provides guidance and structure for the modeling process. A method does not depend on the specific features of the modeling language, because it can be applied to different languages with appropriate adjustments. Therefore, a method must be adapted to company or project specific needs, because it should reflect the goals, requirements, constraints, and preferences of the stakeholders involved in the project

The kind of models that can be exchanged using XMI are instances of MOF models. MOF (Meta-Object Facility) is a standard that defines a metamodeling architecture and a set of metamodels for creating and manipulating models. A metamodel is a model that defines the abstract syntax and semantics of another model. A model is an instance of a metamodel that conforms to its rules and constraints. 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 mapping of MOF concepts to XML concepts. By using XMI, any model that is an instance of a MOF metamodel can be serialized and deserialized in terms of XML elements and attributes. This includes UML, SysML, and other modeling languages that are defined as MOF metamodels. References:
