Abstract

 This memorandum describes a set of MIME types for use with the ISO
 Interlibrary Loan Protocol (ISO 10160/10161). Two MIME types are
 specified below.
 The first is a media type to carry objects which are  BER [BER]
 encoded ISO ILL Protocol Data Units (PDU's). BER are the basic
 Encoding Rules used to encode  PDU's which have been described using
 ASN.1 (Abstract Syntax Notation 1) [ASN.1] .
 The second is for use with the associated document delivery
 instructions.  Document Delivery Instructions (DDI) is an emerging
 protocol which enables automatic electronic delivery of items. It
 allows a request management system (which might have received a
 request for an item via the ISO Interlibrary Loan Protocol (ISO
 10160/10161))  to pass details of the request, item, and delivery, to
 a delivery module, and to receive back reports on the delivery
 process or arrival of an item. It is currently being submitted to the
 ISO TC46/SC4/WG4 committee for approval as an ISO standard.

Registration Information

 Media type name: application
 Media subtype name:  iso-10161-ill-1 - for BER encoded ISO ILL APDU's
 Media type name:  application
 Media subtype name:  ill-ddi - For associated Document Delivery
                      Instructions

Moulton & Needleman Informational [Page 1] RFC 2503 ISO ILL Protocol MIME Types February 1999

 Required Parameter:  transfer-encoding
 For BER-encoded PDU's or DDI's, the only current legal value of this
 parameter is:
  iso-8825-ber
 The transfer-encoding parameter describes the way the PDU has been
 encoded before being submitted to the transport service (in this case
 MIME/RFC822).  The two protocols described in this RFC specify their
 APDU's using ASN.1 (ISO 8824:1990) and the most common way of
 encoding ASN.1 packets is to use the Basic Encoding Rules (BER ISO
 8825)
 The parameter is included to allow future use of these MIME types
 with other encoding schemes. As an example, the ISO 10161 standard
 also describes an encoding method using EDIFACT. In the future, other
 schemes might also be employed. (Since the EDIFACT encoding is not
 currently in use amongst the ISO 10161 and DDI communities, a value
 for the transfer-encoding parameter to describe it is not being
 registered in this RFC.)
 Optional  parameter: iso-10161-apdu-type
 Valid values are:
 ILL-Request
 Forward-Notification
 Shipped
 ILL-Answer
 Conditional-Reply
 Cancel
 Cancel-Reply
 Received
 Recall
 Returned
 Checked-In
 Overdue
 Renew
 Renew-Answer
 Lost
 Damaged
 Message
 Status-Query
 Status-Or-Error-Report
 Expired

Moulton & Needleman Informational [Page 2] RFC 2503 ISO ILL Protocol MIME Types February 1999

 This parameter is optional and can be provided for informational or
 diagnostic purposes. The value of the PDU or DDI type can be
 determined from the actual data sent. The use and format of the PDU's
 and DDI's is defined in the relevant protocol documents which
 describe them.

Examples

 Content-Type: application/iso-10161-ill-1;  transfer-encoding=iso-
 8825-ber; iso-10161-apdu-type=Recall;
 Content-Type: application/ill-ddi;  transfer-encoding=iso-8825-ber;

Encoding

 Since BER encoded material is binary in nature, some form of encoding
 is needed when 7bit or 8bit transport mechanisms are employed.
 The recommended  encoding for BER encoded PDU's  is Base64

PDU's per Message

 When used to send BER encoded PDU's or DDI's. Each MIME body part
 will carry at most one BER encoded PDU or DDI. However, a single MIME
 message containing multiple body parts can be used to transport more
 than one BER PDU and or DDI.

Security Considerations

 There are no known security risks associated with transmitting BER
 encoded PDU's in general. However, a particular BER encoded PDU or
 DDI may have security considerations that make it inappropriate for
 transmittal through public data networks unless appropriate
 protection mechanisms, like encryption, are used. Such a situation
 might occur, for example, when organizations are exchanging documents
 that contain secure or classified information and it is necessary to
 keep information about both the material being exchanged and the
 exchanging partners confidential.

Interoperability Considerations

 BER is an international standard for encoding data meant to be
 transferred between two systems that may store data in different
 local formats internally [BER].
