term.valid? returns false for parsed terms

[ncatlett]

resource_index=ResourceIndex.openbel_published_index("20131211")
term=BEL::Script.parse("p(HGNC:AKT1", resource_index).to_a[-1].subject
term.valid? returns false
param=term.arguments[0].
param.valid? returns true - problem does not seem to be with the namespace value, maybe with accessing the encoding?

The same term entered directly is valid -
p(HGNC['AKT1']).valid? returns true

This is due to missing term signature information on your parsed term. Specifically, the namespace value encoding is not retrieved for the term signature. We should be able to retrieve it from the correct BEL::Namespace::NamespaceDefinition object by calling ns.values[VALUE].
