Scrape the metadata from the <dods URL>.html form of the data. Get a new instance, call parse( <dods URL>.html ), then call getAttr(String varName) which returns a Map of the properties. Note the scraping is only necessary because Jeremy forgot about the .das and .dds extensions. .dds returns the stream syntax. .das returns the metadata.
Creates a new instance of SPDFMetaDataScraper. Use parseData then getAttr after creating the instance.
