Once the ORNL Mercury metadata schema is published at a permanent URI (like, all of the instance documents that conform to this schema just declare so, such as:


This unambiguous typing lets consumers of the file know exactly how to parse it.

Chris-I haven't heard back from folks about the domain registration request. So, I will have to proceed with Plan B that we discussed yesterday, i.e. to add direct location to the server where the XSD actually resides. Please see sample XML and let me know if this works?

Hi Ranjeet,

I've looked over the XML instance documents attached. There's a couple issues to address:

1) We decided to go forward with the namespace string of '', and even though you haven't heard back from the folks yet, I don't see a problem with it. Skye is updating the CN indexing code to look for this namespace, and I'm adding it to the object format list on the CNs. So, a namespace of ornlmercury/schema/v1.0 will be problematic. Let's stick with the persistent URI, and trust that the registration process will be completed in time.

2) In XML instance documents, the schemaLocation attribute should have one or more pairs of URIs, separated by whitespace [1]. The first string in the pair is the namespace, and the second is a hint as to the physical location of the schema for that namespace. So, the documents need to be corrected to have the root element look like:



Notice the single space between the namespace and the physical location. If you want the physical location hint to be a web URI, you could alternatively use:
