 This is the UCSC DAS server.
 
 The DAS specification is at:
     http://www.biodas.org/documents/spec.html
+    that URL says it has been moved to:
+    http://biodas.open-bio.org/documents/spec-1.53.html
 
 DAS alignment extension:
     http://www.dasregistry.org/spec_1.53E.jsp
 
 
 Issues with UCSC server:
    - assignment of category and method is a hard-coded heuristic and
      essentially broken.
 
 General DAS issues:
    - spec doesn't define how specifying both type and category filter show
      behave.
