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.

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 in...
