The Summary Object Interchange Format [Ref. 1] was first defined by the Harvest Project [Ref 2.] in January 1994. SOIF was derived from a combination of the Internet Anonymous FTP Archives IETF Working Group (IAFA) templates [Ref 3.] and the BibTeX bibliography format [Ref 4.]. The combination was originally noted for its advantages of providing a convenient and intuitive way for delimiting objects within a stream, and setting apart the URL for easy object access or invocation, while still preserving compatibility with IAFA templates.

SOIF uses named template types to indicate the attributes which may be contained within a particular summary object. Within the context of a single application, private agreement on the definition of template types has been adequate. As SOIF objects are moved among applications, however, the need for standard, well-specified, and easily identifiable template types increases. This need is particularly intense in the context of query referral, where knowledge of an attribute’s definition and the allowed data types for specific values is crucial. For a discussion of this in the context of the Common Indexing Protocol, see [Ref. 1].

The registration procedure described in this document is specific to SOIF template types. There is ongoing work within the IETF to specify a more generic schema registration facility[Ref. 5]. It is not yet clear whether the results of that work will encompass the ability to register entities like SOIF template types. If it does so, the registration of SOIF template types may be shifted to that method and registry. Should that occur, appropriate pointers will be created in cooperation with the Registrar to ensure that no registrations are lost.

RFC 2656 Registration Procedures for SOIF August 1999

1. Registrar

The initial registrar of SOIF template types will be the Internet Assigned Numbers Authority (IANA).

2. Defining Template Types

Each SOIF object is composed of 3 fundamental components: a template type IDENTIFIER, a URL, and zero or more ATTRIBUTE-VALUE pairs. See [Ref 1.] for the formal grammar of SOIF and a description of how these components interrelate. As part of the registration process, registrants must: propose a template type IDENTIFER; list the ATTRIBUTEs which the template may contain; identify whether each ATTRIBUTE is mandatory or optional; and specifiy the data type and encoding appropriate for the VALUEs associated with each ATTRIBUTE.

2.1 The template type IDENTIFI...
