Descriptions from the class side

I know all the advantages of having the descriptions defined in the instance side. But I find one drawback. Let's suppose I want to implement a tool that works at meta level, and I want a list of the available descriptions of a class in order to build a query where each description will map to a column. Is there any way I can obtain all the instance side descriptors without having to instantiate my object? MyModel has #descriptionA #descriptionB #descriptionC I want something like: MyModel>>#magritteDescriptionOfInstances and get the above mentioned descriptions. I know some descriptions will need specific instance variables in order to work, I would like also to categorize/filter those descriptions that are "class side friendly" (it is, they don't require instance specific behavior). Otherwise I don't see other option than to partition the descriptors to both instance and class side. E.g.: MyModel>>#descriptionA <magritteDescription> ^self class descriptionA MyModel class>>#descriptionA <magritteDescription> ^MAStringDescription new... Any clues? Esteban A. Maringolo
