  1. At minimum, ?info must resolve to a human readable landing page, and should provide a gateway to machine-readable metadata
  2. It is strongly recommended that meta tags with [something like] DC are implemented (I’m suggesting this since they are simple html, and all orgs should be able to do something with those)
  3. Secondary to this, we encourage   organizations are encouraged to use whatever data format[s] is appropriate in their context as the machine-readable data version of ?info, but encourage but encourage that organizations:
  4. Organizations include DC and/or metadata where possible
  5. Organizations use XML or JSON-LD or JSON serializations to express their
  6. Organizations utilize either content negotiation or queries in the form
    1. utilize an established metadata standard (like DC) where possible
    2. utilize an established serialization for their metadata such as XML, JSON, or an RDF serialization such as JSON-LD or Turtle.
    3. express the document type via the “Content-Type:” HTTP header.
    4. utilize either content negotiation or queries in the form “&format=[json|xml
  1. |etc
    1. ]” property to deal with alternative formats.

    Karen: I added c) as a suggestion. I don’t know if you want to indicate a preferred serialization/standard beyond this, or specify minimal metadata fields (the who, what, etc.), or keep it very loose. We could then provide examples that lay out different flavors that are acceptable – I would be willing to contribute an example. 


  1. Some continuity with past
    1. human-readable metadata returned
    2. machine-readable metadata returned
    3. including persistence statements
    4. who/what/when/where paradigm (ERC)
    5. THUMP-like request protocol -- ?info(X,Y) vs ?info&arg1=X&arg2=Y
  2. Never RDF
    1. unfortunately, JSON-LD is RDF; see tweet
    2. however, widely used borrows elements names from JSON-LD and uses them in meta tags, which aren't at risk of RDF complexity
