But who is "we", i.e. what is the use case? If you have a real use for the attributes it's fine, I was just wondering if you'd added things without a concrete idea of what you'd do with them.

OK, but if you have a lot of ports it would be a lot of data to publish. If you changed the type to string you'd get a bit less type checking, but you'd have the flexibility to publish ranges and still be able to have single numbers.

> Side question: the same names (IDFromEndpoint and LocalIDFromManager) are used in the ComputingActivity class. Do we change them as well? CEJobID and LocalJobID?

OK, I missed that. We shouldn't change things in an existing class, and it may be that it would be better to keep the same names for the cloud class - something to discuss.
