1. Abstract

The Common Indexing Protocol (CIP) allows servers to form a referral mesh for query handling by defining a mechanism by which cooperating servers exchange hints about the searchable indices they maintain. The structure and transport of CIP are described in (Ref. 1), as are general rules for the definition of index object types. This document describes SOIF, the Summary Object Interchange Format, as an index object type in the context of the CIP framework. SOIF is a machine-readable syntax for transmitting structured summary objects, currently used primarily in the context of the World Wide Web.

Query referral has often been dismissed as an ineffective strategy for handling searches of Web resources, and Web resources certainly present challenges not present in structured directory services like Rwhois. In situations where a keyword-based free text search is desired, query referral is not likely to be effective because the query will probably be routed to every server participating in the referral mesh. Where a search can be limited by reference to a specific resource attribute, however, query referral is an effective tool. SOIF can be used to create such a known-attribute query mesh because it provides a method for associating attributes with net- addressable resources.

1.1 History

SOIF 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.

Mic Bowman, Darren Hardy, Mike Schwartz, and Duane Wessels each contributed to the creation of the SOIF format as part of the Harvest Project; later work took place as part of the FIND working group.

2. Name

The index object described below will have the MIME type of application/index.obj.HARVEST-SOIF-1.

3. Payload Format

Each summary object has 3 fundamental components: a template type, a URL, and zero or more ATTRIBUTE-VALUE pairs. Because the VALUEs in the ATTRIBUTE-VALUE pairs may contain arbitrary data (cf. Section 3.5), SOIF...
