i am using Papyrus with Eclipse Kepler SR2, trying to make a class-diagram.
I have 2 classes: Product and Order and an association between them. Do i have to add an attribute of type Product in the Order class (i've seen that that's possible) or is the association enough, should i succeed in generating java code from this diagram (which i saw is rather complicated).
I have to mention that I am new to the whole modeling thing and I know that the question may seem idiotic but i really couldn't find an answer anywhere (i've tried google, didn't help) and I would like my diagram to be correct.
Thanks
When adding the association between Product and Order, depending on the type of association, the editor will add an attribute automatically to both entities. So no need to manually add them.

To prioritize the engineering effort around Requirements in a defined way, I came to the idea to use the information already added for the FMEA.
For this I have created a Stereotype named fmeaRelevant (will be named better later), which has several Tags.
My target now is to first calculate the averages of all of these Tags and then from these the average RPN, which is again a Tag.
For this, I have already created a ConstrainedProperty, which has the respective ConstrainedParameters and Constraints.
BindingConnectors are created between the ConstrainedParameters of the ConstraintProperty and the Tags of the Stereotype.
The Stereotype is assigned to my Requirements.
However, Open ConstraintView ... does not show me anything.
Is there anything I am missing?
P.S.: I am not sure how to provide something like a source code snippet for model content. If one makes a proposal in a comment, I will add this.
You used binding connectors between stereotype properties and constraint parameters? That should not be possible, since they are on different levels. The parameters are on the model level and the stereotype properties are on the language level.
Of course, Rhapsody sometimes allows strange things, so it might well be, that there is a way to get it running.
The RPN relates to an actual hazordous situation. Your model describes this situation and all values relating to the situation should therefore be value properties of the FMEAitem. This element would be defined in a library. By the way, this is how it's done in the new RAAML-specification, which might be a useful reference.
I’m interested in defining relationships between custom taxonomies but I’ve been unable to find much in the way of documentation on this topic. Perhaps this can be done using the Pods framework (?), but I'm not sure. What I’d like to be achieved is the following:
There’s the ‘found_object’ custom post type.
There’s the ‘materials’ custom taxonomy for terms like plastic, wood, glass, etc. attached to the ‘found_object’ post type.
There’s also the ‘physical_properties’ custom taxonomy for, say, electrical conductivity and other properties that a given material is known to possess.
I would like to assign the above properties to my materials so that the physical_properties taxonomy terms for each of the found_objects get auto-populated once the materials of an object are selected. Or to reiterate: if an object has one or more materials assigned to it manually this will automatically assign all the properties of these materials to the object and different materials should obviously be allowed to share the same properties.
I need this to let the user arrive at these objects by filtering them by physical properties directly (not by materials per se) using the FacetWP plugin.
I vaguely understand that this can hopefully be done using the Pods plugin by setting up a relationship between my taxonomies by creating a relationship field. But other than that I don’t quite understand what to do.
I would greatly appreciate your help or suggestions.
Kind regards, Svetlana.
The problem can be solved by using the Pods framework in tandem with the FacetWP plugin (by taking advantage of one of its indexer hooks) as is demonstrated here (with the link to the relevant code snippet included).
I wish to extend the person object with additional attributes through an aspect, however several of the aspect properties need to be multi-valued i.e. contain more than one value.
e.g a person's skill set.
How do I achieve this?
What you want to do is define your property with multiple="true" to make it multi-valued. This is detailed in the documentation here.
If you're new to creating Alfesco models, you might find these two wiki pages helpful. The book Professional Alfresco is also recommended, and the modelling section hasn't changed since it was written (though a few other areas have)
I have found help for subclassing of a mapped superclass, and I have found help on how to map a TreeMap. However, I can not find anything that covers using a TreeMap in a subclass at all. Here is the situation: I am adding a function to a long-existing application. That application has mapped entities, a certain set of which, form a hierarchy. There is a , for instance that establishes the base class. Then there are many many MANY subclasses that use the elements to map the individual subclasses. The subclasses all use elements to reference the additional table that holds the attributes of the subclass. This has worked for several years and life has seemingly been good.
Now along comes my work effort and I need to use a TreeMap in my new subclass entity (extending the same base class as all of the others) so the first thing that I do is attempt to map it the same way other subclasses do, with a inside a .
Making the story short, I got an error when I started the app and Hibernate began mapping. Researching this error led me to review the DTD for hibernate mapping files and, guess what? According to my interpretation, one can not configure a Map of any kind inside a .
That same research exposed me to the which CAN contain a Map. So, off I go configuring a inside the base class mapping.
When I did this, I got bizarre errors referencing symbols that I can't even find in the code, in mappings.... anywhere! More research and I find a reference in the Hibernate reference manual, Chapter 9, that says that Hibernate does not support mixing of and elements. So that can't be done either.
My question is: is there a solution that I have missed along the way? From the sound of things it seems that you can NOT configure a map in a subclass if you are using because the inside it won't take a map.... and, while a Map can be configured in a , I doubt that I can gather up much support around here for wading through the current mapping files and re-mapping ALL entities as entities.
Has anybody got any ideas? If I am not looking at this right, believe me, I am willing to accept that and learn!
Let's say
Taxonomy_A is associated to Node_Type_A
Taxonomy_B is associated to Node_Type_B.
AND
Both Taxonomy_A and Taxonomy_B have a term called 'yellow'.
Is it possible to make terms 'yellow' synonymous, so that if I'm looking at a list of 'yellow' stuff, I'm seeing content of both types (Node_Type_A, and Node_Type_B)?
Progress:
Unfortunately it is not possible for taxonomy terms to behave in Drupal as described in my question (at least not without forcing it):
It is clear by taking a look at the terms_related table that it would be possible to create paths that forced related terms together using the taxonomy_get_related function regardless of what vocabulary the term belongs to:
However, the way to get to these terms is through the taxonomy_get_related function in the taxonomy module. This function is not used at all in drupal-6 core except to define it. (I did find it once in the ctools module).
I think you are doing it wrong. I mean using taxonomy wrong, not technically, but as a concept. Ask yourself why do you have 2 vocabularies with term yellow? Both are colour. they belong to same dictionary. Maybe tell little more of what you are trying to make.
Maybe you need to change setup so you don't associate one dictionary to one content type, maybe CCK, views and this module can do what you need http://drupal.org/project/content_taxonomy
