Handling of disallowed space in parameter names

[jbfaden]

The HAPI spec was vague for quite a while about what a valid parameter name is, and some systems handle spaces just fine. Autoplot and the PDS-PPI HAPI server use the parameter name "MAXSIGFLAGS Item 2" successfully, but the verifier does not, and immediately quits with:

  ✗ Dataset urn:nasa:pds:lro-crater:data-der-pri&parameters=MAXSIGFLAGS+Item+2&time.min=2009-06-28T19:00:00.000Z&time.max=2009-06-29T19:00:00.000Z is not in catalog
  Got: to abort

Cannot continue any validation tests due to last failure. Exiting with signal 1.

I think now that the parameter name recommendation is that Java/Python variable names should be used this is not such an issue, but this is still a recommendation, and the verifier should issue a warning and continue.

What URL generated the error? The "+" looks suspect. Parameter names should be URL decoded, so the URL should have %20.

I believe that in the query part of a URL, + and %20 both mean space.

Depends on the header

What is URL or command line call generated the error?

[jbfaden]

I need to figure out where I saw that again. I tried to reproduce the error, thinking it was that the server didn't properly handle %20, but I'm not sure where I saw that.
