Abstract package

  • Key: MOF14-169

  • Summary:

    MOF-RTF issue: Abstract Package

    In MOF 1.3 there is a constraint which says that Package cannot have
    isAbstract attribute set to true.
    However, it does make sense to have abstract packages in MOF.
    One example of an abstract package could be a package containing some basic
    set of primitive datatypes which I would like to reuse in my models. There
    is no reason to instantiate this kind of package - the result of
    instantiation of this package would be nothing more than an empty package
    proxy object.

MOF 1.3: are Associations contained in Packages or not?

  • Key: MOF14-168
  • Legacy Issue Number: 3527
  • Status: closed  
  • Source: Model Driven Solutions ( Mr. Steve Cook)
  • Summary:

    Section 3.3.4 of MOF 1.3 gives a table that shows allowed containments.
    According to this table, Associations cannot be contained in anything.

    Sections 5.2.1 and 5.2.2 give examples where an Association (A) is
    contained in a Package (P1).

    These seem inconsistent.

Is the multiplicity of Model::Tag::values correct?

  • Key: MOF14-87
  • Legacy Issue Number: 2465
  • Status: closed  
  • Source: Anonymous
  • Summary:

    Summary: A Tag has an attribute called "values" with type "any" and multiplicity
    of [0..*] / ordered == false / unique == false. On thinking about this
    (while specifying some Tags for the IDL mapping), I"ve concluded that
    the multiplicity is probably wrong. It would be better if it was either
    [1..1] or [0..*] / ordered == true / unique == false.

    in 5.3.6, the IDL for the "remove_value_at" operation should not have
    an "existing_value" argument. [The IDL in the appendix is correct, as
    are the templates for the "specific" equivalents.]

MOF RTF Issue: typos in Reflective.idl

  • Key: MOF14-47
  • Legacy Issue Number: 3533
  • Status: closed  
  • Source: DSTC ( Stephen Crawley)
  • Summary:

    We've spotted two minor typos in the Reflective.idl in Appendix B.2 of
    the MOF 1.3 spec.

    1) The constant called "WRONG_DESIGNATOR_DESIGNMATOR_VIOLATION"
    should be renamed to "WRONG_DESIGNATOR_VIOLATION".

    [The constant is described correctly in section 5.4.6 on page 5-31]

    2) The "ref_unset_value()" operation in "RefObject" is missing
    a parameter. It should be declared as:

    void ref_unset_value(in DesignatorType feature) raises (MofError);

    [The operation is described correctly in section 6.2.3 on page 6-13]

"*" not needed on DataType name

  • Key: MOF14-46
  • Legacy Issue Number: 3529
  • Status: closed  
  • Source: Google ( Don Baisley)
  • Summary:

    The MOF 1.3 Specification, section 3.4.7, says a DataType that does not
    require an IDL declaration must have a "name" that starts with a "*"
    character. This is an unnecessary restriction which has been generally
    ignored. MOF Model does not start DataType names with a "*" (see Appendix A
    XML defining any, boolean, string, and unsigned long). Similarly, the UML
    metamodel and others ignore this unnecessary restriction.

    The restriction is particularly inappropriate because it restricts
    ModelElement names based on the IDL mapping. IDL rules should not restrict
    ModelElement names, first because a Tag can be used to select an alternate
    IDL name, and second because a DataType mapped directly to a predefined IDL
    type does not cause an IDL declaration to be generated (so the DataType name
    is irrelevant to IDL generation).

    Recommendation: remove the restriction that a DataType not requiring an IDL
    declaration have a "name" starting with a "*" character.

MODL Appendix needs updating

  • Key: MOF14-50
  • Legacy Issue Number: 4154
  • Status: closed  
  • Source: DSTC ( Stephen Crawley)
  • Summary:

    In MOF 1.3 RTF, it was agreed (with some reluctance on my part) that the
    spelling of the model element names in the XMI version of the MOF Model
    was definitive. This means that the MODL definition of the Model package
    in the Appendix is out of date.

    In addition, DSTC has made a number of changes to the MODL language
    syntax that mean that the version in the MOF 1.3 spec no longer
    compiles.

    Finally, the URL for the specification of the MODL language is stale.

Model::Contains::container return type wrong

  • Key: MOF14-49
  • Legacy Issue Number: 4133
  • Status: closed  
  • Source: DSTC ( Stephen Crawley)
  • Summary:

    The "Contains" Association is defined with the "container" end having
    type "Namespace" and multiplicity [0..1]. According to the MOF to IDL
    mapping (see 5.8.10 <association_end1_name>) this means that the
    Model::Contains::container() operation should return a "NamespaceBag".

    However, the IDL in both Chapter 3 and Appendix C incorrectly declares
    Model::Contains::container() as returning a "Namespace".

Can MOF Class contain a Constant?

  • Key: MOF14-45
  • Legacy Issue Number: 3528
  • Status: closed  
  • Source: Google ( Don Baisley)
  • Summary:

    The MOF 1.3 Specification shows in table 3-4 that a Class can contain a
    Constant. But constraint [C-15] ClassContainmentRules does not allow a
    Class to contain a Constant. The table and the constraint need to say the
    same thing. Since MOF's Model.ModelElement contains Constants, it is clear
    that the table is correct.

    Recommendation: add Constant to ClassContainmentRules.

MOF 1.3 Why have rule against abstract packages?

  • Key: MOF14-44
  • Legacy Issue Number: 3446
  • Status: closed  
  • Source: Google ( Don Baisley)
  • Summary:

    In the MOF 1.3 Specification, constraint C-44, which prevents a package
    being abstract, does not appear to serve any useful purpose. It does
    prevent definition of general, abstract metamodels that must be subclassed
    with more specific metamodels in order to be deployed. A MOF package
    defines a type of a package extent, and such types support polymorphism
    through package inheritance. The concept of abstract packages is as useful
    to metamodeling as the concept of abstract classes is to object modeling.

    Recommendation: Delete C-44.

  • Source: Object Radiance ( GK Khalsa)
  • Summary:

    The MOF specification defines the AttachesTo association as ordered on
    the Tag end (given a ModelElement, its tags are ordered). The IDL for
    for AttachesTo interface is consistent with this definition. However,
    the IDL definition of the Tag interface provides an add_elements_before
    operation, which is inconsistent with the Association definition in the
    metamodel. Presumably, that operation is included in error, and should
    be removed.

Reflective IDL fix for CORBA 2.3

  • Key: MOF14-37
  • Legacy Issue Number: 2971
  • Status: closed  
  • Source: DSTC ( Stephen Crawley)
  • Summary:

    The Reflective module contains the following IDL type alias:

    typedef any ValueType;

    Unfortunately, CORBA 2.3 has added a new IDL keyword "valuetype". Hence a
    CORBA 2.3 compliant compiler will give syntax errors for the Reflective IDL.

    Possible solutions include:

    1) Replace "ValueType" with "_ValueType" throughout the
    Reflective module.

    2) Change "ValueType" to another name; e.g. "CorbaValueType".

    3) Remove the typedef, and replace all instances with "any".

Incorrect return type for Assoc query operation

  • Key: MOF14-42
  • Legacy Issue Number: 3379
  • Status: closed  
  • Source: DSTC ( Stephen Crawley)
  • Summary:

    The description of the single ended Association query operation has
    (I think) the wrong return type for an "optional" association end.
    The operation can return either zero or one instances. This could
    be expressed as either the base type or a "bag" collection. The
    former is easier to use, and what the spec used to prescribe in MOF 1.1.
    However, the text of the template description [section 5-10-8 on page
    5-62] currently prescribes the latter.

    I think this is just a typo in MOF 1.3. However, it could be that the
    change was deliberate, and I've forgotten why we decided to make it.

    At any rate, the 1.3 mapping description now inconsistent with the IDL
    for the MOF Model in Appendix B. Examine the IDL interface for the
    "contains" Association. The "container" end has multiplicity [0..1]
    yet the "container(ModelElement)" operation returns a Namespace, not
    a NamespaceBag as the text of the mapping spec requires.

MOF 1.3 Incorrect attribute order in diagrams

  • Key: MOF14-43
  • Legacy Issue Number: 3444
  • Status: closed  
  • Source: Google ( Don Baisley)
  • Summary:

    In the MOF 1.3 Specification, the order of attributes shown in some of the
    diagrams and their descriptions is inconsistent with the order given in the
    XML and IDL. Particularly, GeneralizableElement and AssociationEnd show
    attributes out of order. The diagrams, explanative text, XML and IDL should
    all show features in the same order because order is relevant when
    determining the order of parameters passed to a create operation. A diagram
    showing attributes out of order can lead one to pass creation arguments in
    the wrong order.

    Recommendation: fix the order in the diagrams and explanations.

  • Key: MOF14-59
  • Legacy Issue Number: 4413
  • Status: closed  
  • Source: DSTC ( Stephen Crawley)
  • Summary:

    There is currently no standard way to direct the MOF IDL mapping to
    output a #pragma version for a declaration. This is needed when a
    standard meta-model is changed in a way that gives IDL interfaces, etc
    with the same name but different signatures.

::Model::Package::internalize/externalize in MOF 1.4

  • Key: MOF14-58
  • Legacy Issue Number: 4396
  • Status: closed  
  • Source: DSTC ( Stephen Crawley)
  • Summary:

    The Package class has two operations "internalize" and "externalize" that
    are supposed to be hooks for importing and exporting metadata. They are
    defined in MOF 1.3 with Parameters whose type is a CORBA Any and that
    represents some kind of input / output stream. This won't work in MOF
    1.4 because "Any" is not a supported data type.

Move the 'verify' operation to RefBaseObject

  • Key: MOF14-57
  • Legacy Issue Number: 4384
  • Status: closed  
  • Source: DSTC ( Stephen Crawley)
  • Summary:

    Meta-modelling the 'verify' Operation on Model::ModelElement is going to be
    problematical in MOF 1.4 because one of its Parameters contains a CORBA any.
    We could solve this by moving the operation onto the (IDL) RefBaseObject
    interface. This would have the additional benefit of providing an API
    for invoking constraint validation on any meta-object.

Primitive data types usage in the MOF Model.

  • Key: MOF14-56
  • Legacy Issue Number: 4351
  • Status: closed  
  • Source: DSTC ( Stephen Crawley)
  • Summary:

    In MOF 1.3, the Model contains references to the following primitive (IDL)
    data types: boolean, long, unsigned long, any, string and TypeCode. Some
    of these are 'typedef'd.

    In MOF 1.4, the status of the primitive types is as follows:

    boolean – required
    long – 32 bit signed integers – required (for MultiplicityType)
    unsigned long – 32 bit unsigned integers – not required
    (its use in MOF 1.3 was a typo ... )
    any – maybe required for Constant, Constraint and Tag.
    TypeCode – not required
    string – required, but see below.

    There are a couple of loose ends though:

    1) The "any" type would need to be a 5th standard PrimitiveType. It has
    been suggested that we can use a string type to represent the 'value'
    field of Constant, the 'values' field of Tag and the 'expression' field
    of Constraint. Tags and Constraints are straightforward, but using
    a string to represent a Constant value would entail defining standard
    concrete (string) syntaxes for the kinds of values allowed for Constants.

    Proposal: Replace all occurrences of 'any' in the MOF Model with a 16 bit
    UTF string type.

    Proposal: Adopt the IDL syntax for integer, floating point and wide string
    literals with minor modifications as required. (It would be a good idea
    to use an encoding that works with 8 bit character sets ... )

    2) In MOF 1.3, "string" is used for various things such as NameType,
    AnnotationType, DependencyKind and FormatType along with the type
    of 'tagId'. Note that this is an 8 bit string type. Apparently
    this causes problems for some meta-modellers. At any rate, now
    would be a good time to start supporting international character
    sets in meta-models.

    Proposal: Change all 'string' types in the MOF Model to a 16 bit UTF
    string type.

    Proposal: Remove all cosmetic typedefs.

Error in MOF 1.3 XMI - ViolationType

  • Key: MOF14-55
  • Legacy Issue Number: 4313
  • Status: closed  
  • Source: DSTC ( Stephen Crawley)
  • Summary:

    The XMI document for MOF 1.3 gets the type of the 'values_in_error'
    field of 'ViolationType' wrong. It says that the type is an IDL
    interface type called ::Reflective::NamedObjectList. In fact the
    type's name is ::Reflective::NamedValueList, and it is a typedef
    of a sequence of a struct ... not an interface.

predefined tag for marking attributes needed

  • Key: MOF14-53
  • Legacy Issue Number: 4237
  • Status: closed  
  • Source: France Telecom R&D ( Mariano Belaunde)
  • Summary:

    Need a predefined tag for marking attributes that will 'act as a
    qualifier' in a classifier.
    In a metamodelling tool it may be useful to derive automatically an object
    identifier from one
    or more relevant attributes of the classifier (for instance a 'name'
    attribute).
    Note: The attribute 'acting as a qualifier' is owned by the classifier not
    by an association.
    Suggestion: pre-define a Tag named 'actAsQualifier : Boolean' applicable to
    any attribute
    of a classifier.

MOF IDL change

  • Key: MOF14-52
  • Legacy Issue Number: 4211
  • Status: closed  
  • Source: ETA Sistemi Srl ( Davide Mora)
  • Summary:

    i suggest to change the IDL from:

    typedef any ValueType; typedef sequence < ValueType > ValueTypeList;

    to:

    typedef any AnyType; typedef sequence < AnyType > AnyTypeList;

    because "valuetype" it's a reserved word for the newest versions of IDL and cause an error.

    There is also "strange character" in the following const:

    const string INVALID_DELETION_VIOLATION = (character)org.omg.mof:reflective.invalid_deletion(character);

    the "(character)" have to be replaced with '"'.

    I suggest also to split the .txt in 2 files .idl, or explain in the download page how the .txt have to be splitted.

MofError when Operation impl violates structural constraints

  • Key: MOF14-54
  • Legacy Issue Number: 4295

  • Source: DSTC ( Stephen Crawley)
  • Summary:

    The description of the behaviour of an Operation does not say what ought
    to happen if an Operation's implementation returns parameters or results
    that violate multiplicity constraints. Similarly, for Exception parameters.
    This affects sections 5.8.13 and 6.2.3 ("refInvokeOperation").

MOF Unbounded should have type long

  • Key: MOF14-51
  • Legacy Issue Number: 4175
  • Status: closed  
  • Source: Google ( Don Baisley)
  • Summary:

    The MOF 1.3 Specification defines the constant UNBOUNDED
    like this:

    const unsigned long UNBOUNDED = -1;

    The type should be long, not unsigned long. The value is used
    for MultiplicityType.upper which has type long. Also, the
    constant has a signed value.

    The IDL clearly contains a typo. Fix it so that UNBOUNDED is signed
