metamodel

I have to say that complexity of the metamodel would not rank at the top of my list of complaints about BPDM.

The language of a model is often called a metamodel, hence the language for defining a modeling language is a meta-metamodel.

This approach can help you to understand the domain better, optimize the metamodel, and enable you to develop a tool-friendly metamodel.

Domains in DSL and DSM are often captured in the form of a metamodel, as shown in Figure 1.

However, following a top-down (or any other approach) for capturing a metamodel does not guarantee tool friendliness.

This model provides a uniform representation of the system, which conforms to a given metamodel expressing the chosen viewpoint.

Subject to the constraints of the UML metamodel, any model element might be a provider, a consumer, or both.

As a result of these changes, the applications database calls are now directed to the MetaModel Database.

Consider the following items when trying to capture a good metamodel.

The Metamodel API can be used to dynamically access the metamodel information for a persistence unit.

This Person_ metamodel class is an alternative means of referring to meta information of Person.

To further the analogy, an equivalent concept of run-time scope is needed for the metamodel interfaces.

The constraints of the modeling environment and tooling will guide you to develop a valid metamodel.

A metamodel uses MOF to formally define the abstract syntax of a set of modeling constructs.

Hence, the models intrinsic to a modeling approach must themselves be described in a model, which we call a metamodel.

Even the models (UML, XML schema) are represented as a data set; this special data set is called the metamodel.

Figure 2 is an excerpt from the metamodel that describes the class, one of the central concepts in class diagrams.

You should be familiar with the basic methodology metamodel and be able to define and customize method elements.

The UML metamodel describes in precise detail the meaning of a class, an attribute, and the relationships between these two concepts.

Software Process Engineering Metamodel (SPEM) is the standard specification that formally describes the software development processes.

With the metamodel, tool friendliness refers to how easy it is to design and develop a tool for a specific metamodel (DSL).

Streamlined, then, is a framework with a rich metamodel that enables application generation.

They are less than 50 lines long and deal with a small subset of the UML metamodel.

As previously mentioned, the server-side metamodel represents the deployment-oriented part of the CWM OLAP metamodel.

The persistence provider is expected to generate these metamodel classes for you.

I've defined a metamodel class as a description of a persistent entity class.

Do not build diagram editors right away from the first instance of the metamodel; use simpler model editors, such as EMF tree editor, first.

The metamodel Person_. age field is declared to be of type javax. persistence. metamodel. SingularAttribute.

All the server-side metamodel definitions exist within the javax. olap. serversidemetadata package.

These metamodel constructs can be generated statically or dynamically.

The MetaModel Database is an abstraction only and does not actually hold any data: It is simply a model.

For all practical purposes, a stereotype is a form of inheritance in the metamodel.

Your metamodel becomes your higher-level programming language, increasing your productivity.

A more evolved metamodel would enforce integrity and constraints using OCL (see Resources).

Provides an overview of the metamodel underlying Distributed System Designers.

In UML 1, the basic units of compliance were defined by the packages of the metamodel, with literally hundreds of possible combinations.

Apply the separation of concerns principles while capturing the metamodel (componentize your models).

The metamodel describes what types of entities make up the schema.

Anyway, to generate an XML schema from a UML model, it suffices to decide which concept from the UML metamodel matches which XML schema tag.

You may have noticed that the public static fields are only declared in canonical metamodel but not initialized.

You may find more than one sensible mapping between the UML metamodel and XML schema.

MoDisco also provides and uses concrete implementations of Knowledge Discovery Metamodel (KDM) and Software Metrics Metamodel (SMM).

A message model is a specific application of a metamodel; an example of a content model is a specific XML schema.

It also generates an EMF Ecore metamodel; the generated parser instantiates this metamodel from sentences of the language.

A notion of instance in this metamodel is different from the notion of instance used in OO.

Once you have imported the Ecore metamodel, you are ready to extend it.

If the application developer writes the metamodel classes, they are called non-canonical metamodel.

The Corent Multi-Tenant Server is built on a service oriented architecture that uses a MetaModel Database (described in Step 1).

OMG released a draft of SoaML, a specification for the UML Profile and Metamodel for Services.

Next, you specify custom user interface options through the metamodel, such as how you want Streamlined to display relationships.

Constraints defined in the metamodel are a key enabler for semantics.

This article introduces the Criteria API and the closely associated metamodel concept.

The class structure for the source code thus imitates the UML metamodel closely.

A message model itself is based on a metamodel, a way of representing message content.

Comments or extensions to the metamodel link your models to the code being analyzed.

Eobject. org's open-source Java framework MetaModel implements a unified API for the access, exploration, and query of different datastores.

These client-side metamodel elements are inherited from the CWM metamodel.

The package EcoreX is, of course, the extended metamodel.

Trust me, they are included in the complete UML metamodel but they are not useful for this article.

So people begin the research on metadata, this resulted in the CWM(Common Warehouse Metamodel) published in 2001 by OMG.

The metamodel is available free of charge after registration.

As I explained in the previous article, you will need to review the UML metamodel to interpret these.

A custom profile extends UML without changing the base metamodel.

The Criteria API's strong type checking is based on the availability of instantiated metamodel classes at development time.

Metamodels are self-describing, using DSL to capture the metamodel (domain) for the DSL.

Johan also explains the importance of ontological metamodel hierarchies.

These views represent the core of the CBDI SAE metamodel.

Generate an EMF Editor for the metamodel, and install its plug-in.

We have seen how to extend the Ecore metamodel to conceptualize simple programmatic behavior within a synthetic Java method.

An example of a message metamodel is the XML Schema definition language; in fact, that is the most common metamodel found in ESB products.

In the RAS specification, the RAS metamodel is expressed in UML.

You can create or import the metamodel described above.

In technical terms, it is a metamodel of the category.

Capturing a metamodel is a type of abstraction, which is a skill often found with architects.

The third approach, an improved metamodel, is the foundation of Streamlined.

This metamodel (Figure 2) describes component types, interfaces, and data structures 11.

We have now designed an extended metamodel and used it to describe a concrete model called My. ecore (see EMF V2. 5 file name note, above).

For coherence, the metamodel is written in UML.

Quite naturally, if you have many persistent entities you will not be inclined to write the metamodel classes yourself.

The other property is whether it is a metamodel.

In the build step, we will create the metamodel genmodel and build the model and the editor projects.

They could model these issues according to the SOAD metamodel.

There is also a JPA 2. 0 metamodel API that enables the developers to dynamically access the database metamodel information.

Xtext lets you define both the syntax and the metamodel behind your grammar at the same time.

For example, think of SPEM as the process engineering metamodel.

SAE metamodel v2. 0 was designed with the input of customers and the feedback they gave on v1. 0.

First, I'll show you the metamodel.

DSL with too many elements (often a result of not identifying patterns) or the model element instances end up in the metamodel

This makes it easier to integrate the pre-built metamodel with the concrete model development in the next section. To do this

The corresponding static canonical metamodel class of domain. Person is shown in Listing 4
