• 3.1.3 Translator
  "The mdTranslator converts an input metadata record, written to a known JSON standard, such as the ADIwg JSON standard."
  This sentence was confusing to me when I read it the first few times. I think it might be clearer if this sentence were combined with the one that follows it, like this:

"The mdTranslator can be used to convert a well-formatted input record from one compliant standard (such as the ADIwg JSON standard) to another metadata standard (such as the ISO 19115-2 standard, in XML). Currently the mdTranslator supports only the ADIwgJSON to ISO XML conversion, but additional translation capabilities may be added in the future."

• 3.1.1 Viewer, 3.1.2 Validator, 3.1.3 Translator
  It might be good to eventually have pointers/URL's to these resources somewhere in this documentation to help users find them (in case they happen to be reading the documentation as a stand-alone doc somehow), as well as know specifically what is being referenced when the documentation describes something. I know the location of these may not be fixed yet... consider a placeholder?
