Fragment and partially load EMF models in xmi format [message #1255575]

Hi,

EMF models stored in the xmi format are not very scalable. I found that large models during manipulation give out of memory errors.

We have a product build using EMF and the model files are stored in XMI format.
Are there tools available to fragment an EMF model? Also, is it possible to load and unload fragments on demand given that we have to retain the XMI format for the model files?

I would appreciate any pointers in this area.

Thanks,
Balaji

Yes there are many options.

You could fragment your model : https://wiki.eclipse.org/EMF/FAQ#How_can_I_split_containment_references_across_multiple_resources_to_support_cross_resource_containment.3F

You could also use another serialization format which better suits your needs.
Have a look at this presentation :
