FYI, if you aren't aware, what you are calling namespace_asset is a JSON Pointer

Oh, good to know! I'm not sure if it's strictly a JSON pointer? Essentially, when trying to specify a certain deployment - I'm trying to avoid requiring the entire blockchain URI. Do you think that's a bad idea?
Basically...
ethpm://maker.ethpm.eth:1/[email protected]/deployments/DeploymentName
Is what you would need to fetch the DeploymentName deployment on the mainnet . . . . It seems like there might be some edge cases where this isn't ideal - in terms of forked chains that share a chain ID? Since this is for the widget - I was thinking of just specifying that a registry URI with a pointer/namespaced asset only supports the 5 main chains.

These two lines can be replaced with:
pkg_id, _, namespaced_asset = pkg_path.partition('/')

This call still jumps out to me as a minor problem. It relies on validation that happens outside of this function. If you change this to pkg_name, _, safe_pkg_version = pkg_id.partition('@') then this code would be slightly more robust. Totally a nitpick on my part.

What was wrong?
Updated the ethpm uri parsing functions to support namespaced assets.
ethpm://compound.ethpm.eth:1/[email protected]/deployments/cDaiThis will be useful in the ethpm widget - so that all the data needed to fetch the contract address of a deployment is in a single url.
