Abstract This document specifies a method of using the Atom Syndication Format as an export format. Sneddon Expires November 24, 2009 [Page 1] Internet-Draft Atom Export Format May 2009 1. Introduction [[anchor2: This section is yet to be written.]] 2. Conformance Requirements The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119]. 3. Atom Export Documents An Atom Export Document is an Atom Feed Document [RFC4287]. atom:entry elements are given purpose within the document by an atom: category element whose the scheme attribute is equal to "XXX-to-be- decided" and whose term attribute matches one of the below: 1. "post" signifies the entry represents a blog post. Furthermore, an atom:category with scheme "http://schemas.google.com/g/2005#kind" and term "http://schemas.google.com/blogger/2008/kind#post" SHOULD be treated as equivalent. 2. "comment" signifies the entry represents a reply to a post which MUST be in the same Atom Export Document and which MUST be specified by an thr:in-reply-to element [RFC4685] within the entry. Furthermore, an atom:category with scheme "http://schemas.google.com/g/2005#kind" and term "http://schemas.google.com/blogger/2008/kind#comment" SHOULD be treated as equivalent. Such an atom:category element MUST be the first element child of the atom:entry. If it is not, implementations MUST NOT incur any meaning from it. Any atom:entry which does not have such an atom:category element is assigned absolutely no meaning by this specification. 4. Further Recommendations This section is informative. If an implementation wishes to store data beyond what is easily representable within Atom for importing/exporting state, it is Sneddon Expires November 24, 2009 [Page 2] Internet-Draft Atom Export Format May 2009 recommended that a namespace is created to contain this extra metadata, and it is not coerced in an over-engineered manner into Atom. 5. Security Considerations As Atom Export Documents are just Atom Feed Documents, please see the "Security Considerations" section of [RFC4287]. Furthermore, as they can contain extensions from [RFC4685], please see that document too. 6. IANA Considerations This document has no IANA considerations. 7.
